Differences Between GS63B/6D-S8-50128010 and WFS3-40P415 Label Gap Sensors

Choosing between the GS63B/6D-S8-50128010 vs WFS3-40P415 Label Gap Sensors requires more than checking their basic detection capabilities. Both models support label detection in automated production environments, but their mechanical construction, electrical outputs, adjustment methods, and environmental specifications differ in several important areas.

The Leuze GS63B/6D-S8-50128010, offers a 61 mm fork depth, a push-pull switching output, and an IP67 protection rating. The SICK WFS3-40P415, part number 6043919, features a 42 mm fork depth, a PNP switching output, and an IP65 protection rating.

Both manufacturers specify a 3 mm fork width, a minimum label gap of 2 mm, a 10 kHz switching frequency, and a response time of approximately 50 microseconds. Therefore, buyers should pay particular attention to the differences in mechanical dimensions, output compatibility, adjustment arrangements, and environmental protection.

This comparison examines the specifications and practical differences between these exact models. It also explains which option may better suit different packaging, printing, and automated labelling requirements.

GS63B/6D-S8-50128010 vs WFS3-40P415: Complete Specification Comparison

The following table compares the published manufacturer specifications for both products.

Important specification note: Leuze identifies the minimum detectable label width and minimum label gap separately as 2 mm. SICK specifies a minimum detectable object of 2 mm for the gap between labels or label size, depending on label thickness. These descriptions are related but should not be treated as identical test conditions.

Difference in Fork Width and Fork Depth

Fork dimensions represent one of the most important differences between the Leuze GS63B/6D-S8 and SICK WFS3-40P415.

Both models have a 3 mm fork width. However, their fork depths differ considerably.

The Leuze model provides 19 mm more fork depth than the SICK model. This difference can influence sensor placement when the machine uses a specific label path or requires the sensing area to sit farther inside the sensor housing.

How the Leuze fork depth affects installation

The GS63B/6D-S8 has a 61 mm mouth depth. This provides a deeper sensing area compared with the 42 mm fork depth of the WFS3-40P415.

Buyers should consider this dimension when the label web travels through a machine with a longer insertion path or when the existing mounting arrangement requires greater fork depth.

Its overall dimensions of 11 × 30 × 80 mm also make it physically larger than the SICK alternative.

However, a deeper fork does not automatically improve detection accuracy. The machine designer must check the label path, sensor alignment, available clearance, and mounting position before selecting the model.

How the SICK fork dimensions differ

The WFS3-40P415 has a more compact mechanical design. Its 42 mm fork depth and 64.3 mm overall depth may make it easier to accommodate in installations with restricted mounting space.

It also weighs approximately 36 g, compared with 55 g for the Leuze sensor.

This difference may matter when engineers design lightweight brackets or retrofit an existing labelling station.

Which model has the advantage?

• Choose the GS63B/6D-S8 when the installation requires its 61 mm fork depth.
• Consider the WFS3-40P415 when a 42 mm fork depth and more compact overall dimensions suit the available mounting space.

The final decision should follow the machine’s mechanical drawing rather than the sensor’s overall size alone.

Difference in Output Configuration

Output configuration is another major consideration in the GS63B/6D-S8 vs WFS3-40P415 comparison.

The Leuze sensor uses a push-pull transistor output, whereas the SICK sensor uses a PNP switching output.

Although both models support a maximum switching current of 100 mA, their output configurations are different.

Leuze GS63B/6D-S8 push-pull output

The GS63B/6D-S8 provides one digital switching output with a push-pull transistor switching element.

Its published switching voltage specifications are:

• High signal: ≥ (UB – 2 V)
• Low signal: ≤ 2 V
• Maximum switching current: 100 mA

A push-pull output can actively provide high and low signal states. This arrangement offers flexibility when integrating the sensor with suitable digital input circuits.

However, engineers should still check the PLC input specifications, input common configuration, and electrical wiring diagram before connecting the sensor.

SICK WFS3-40P415 PNP output

The WFS3-40P415 uses a PNP switching output.

Its published specifications include:

• Switching output: PNP
• Maximum output current: 100 mA
• Light/dark switching: Selectable
• Teach-in input: PNP

The PNP configuration makes this model a suitable option for control systems designed around compatible sourcing-type digital inputs.

The PLC input must support the sensor’s voltage levels and switching arrangement. Buyers should also check the teach-in input requirements when they plan to control sensor adjustment through the machine controller.

Practical PLC compatibility differences

The output type can influence the wiring and integration work during installation.

For example, a machine that already uses compatible PNP inputs may offer a straightforward integration path for the SICK WFS3-40P415.

The Leuze push-pull output provides a different electrical arrangement. Engineers should verify the PLC input circuit before connecting it, even if the controller supports conventional 24 V DC digital signals.

Do not assume that both sensors offer interchangeable wiring simply because they share the same supply voltage and connector type.

Selection recommendation: Check the PLC input configuration first. Choose the Leuze model when its push-pull output matches the control system. Consider the SICK model when the machine requires a compatible PNP output.

Difference in Response Time and Switching Performance

Response time and switching frequency are two separate specifications. Buyers should examine both when selecting a sensor for high-speed labelling machinery.

The good news is that both models offer closely matched performance specifications.

Response time comparison

The Leuze GS63B/6D-S8 specifies a response time of 0.05 ms, equivalent to 50 microseconds.

The SICK WFS3-40P415 specifies a response time of no more than 50 microseconds.

Therefore, the published response-time specifications do not establish a meaningful speed advantage for either model.

Response time describes the time required for the sensor output to respond to a detection change under the manufacturer’s specified test conditions.

For a high-speed packaging machine, a shorter response time can help the control system detect closely spaced label transitions. However, actual machine performance also depends on label movement, controller scan time, input filtering, and output processing.

Switching frequency comparison

Both models have a switching frequency of 10 kHz.

This means their published maximum switching-frequency ratings match.

A 10 kHz switching frequency indicates the sensor’s specified switching capability. It does not mean that the machine can automatically process 10,000 labels per second.

The actual production rate depends on label dimensions, gap spacing, conveyor speed, PLC processing, and the complete machine configuration.

What does this mean for high-speed labelling?

Consider a machine that processes labels at high conveyor speeds.

If the sensor must detect small gaps repeatedly, engineers need to evaluate both the switching frequency and the response time.

Since the two products share the same published 10 kHz switching frequency and approximately 50 µs response time, these specifications alone do not justify choosing one over the other.

Other differences, particularly output configuration and fork depth, should influence the decision.

Selection recommendation: Neither model has a clear specification-based advantage in switching frequency or response time. Compare the complete detection and control-system requirements before choosing.

Difference in Label Detection Capability

Label detection performance is another important part of this comparison.

Both manufacturers specify a minimum label gap of 2 mm or an equivalent 2 mm detection requirement. However, their product descriptions provide slightly different information about label detection.

Leuze label detection specifications

Leuze specifically identifies the GS63B/6D-S8 for detecting non-transparent labels.

Its product information lists:

• Minimum label width: 2 mm
• Minimum label gap: 2 mm
• Infrared light source: 940 nm
• Pulsed transmitted signal

These specifications provide useful information for buyers working with conventional non-transparent label materials.

However, the manufacturer does not establish universal detection performance across every material thickness, surface finish, or label construction.

SICK label detection specifications

The SICK WFS3-40P415 specifies a minimum detectable object of 2 mm.

The manufacturer describes this specification in relation to the gap between labels or label size and adds that performance depends on label thickness.

This qualification matters when selecting the sensor for thin labels or tightly spaced label sequences.

Buyers should test the actual label stock rather than relying only on the nominal 2 mm specification.

How label material affects model selection

Label material can influence the detection performance of either sensor.

For example, transparent labels, thin films, reflective surfaces, and unusual substrate combinations may require additional testing.

The Leuze product page explicitly states detection of non-transparent labels. The cited SICK specification does not provide an equivalent universal material-compatibility statement.

Therefore, buyers should not assume that both products offer identical performance with transparent labels.

What about very small label gaps?

Both models specify a 2 mm minimum label gap.

If a production line uses gaps smaller than this value, neither product should be selected solely on the basis of its published minimum-gap specification.

The engineering team should discuss the application with the manufacturer or supplier and conduct an actual production-line test.

Selection recommendation: Both products offer a 2 mm published minimum detection specification. Consider the Leuze model when its explicitly stated non-transparent label application matches the job. Evaluate the SICK model against its label-thickness qualification and actual material requirements.

Difference in Adjustment and Teach-in Features

The adjustment arrangements differ more noticeably than the basic detection specifications.

The Leuze GS63B/6D-S8 uses a multiturn potentiometer. The SICK WFS3-40P415 provides plus/minus adjustment buttons and cable-based teach-in functionality.

This difference can influence commissioning time, maintenance procedures, and how operators configure the machine.

Leuze GS63B/6D-S8 adjustment

Leuze provides a multiturn potentiometer for adjusting the GS63B/6D-S8.

The adjustment mechanism gives technicians a manual method to configure the sensor during installation and maintenance.

Its published technical specifications also include a maximum conveyor speed of 20 m/min during teach-in.

This detail matters when engineers configure the sensor while the label material moves through the production machine.

The product also has two LEDs for operating and status indication.

SICK WFS3-40P415 adjustment

SICK offers more detailed teach-in functionality for the WFS3-40P415.

The manufacturer specifies:

• Plus/minus adjustment buttons.
• 2-point teach-in.
• Dynamic teach-in.
• Sensitivity adjustment.
• Selectable light/dark switching.
• Cable-based teach-in functionality.

The sensor allows technicians to adjust the switching threshold using the buttons.

SICK also provides an electrical teach-in input. Its published requirements specify a teach signal above 5 V and below the supply voltage, while the run state requires less than 4 V.

This provides an additional configuration option for machine designers who want to incorporate sensor adjustment into their control arrangements.

Which adjustment method is more suitable?

The two adjustment systems serve different commissioning preferences.

The Leuze potentiometer offers a manual adjustment arrangement. Technicians who already work with Leuze GS-series sensors may find this approach familiar.

The SICK model offers more documented adjustment functions, including dynamic teach-in and a dedicated electrical teach-in input.

For production environments that frequently change label formats, the SICK adjustment options may provide additional flexibility.

However, this does not automatically make the SICK model the better choice for every installation. The actual commissioning procedure, operator requirements, and machine-control design remain important.

Selection recommendation: Consider the GS63B/6D-S8 for potentiometer-based manual adjustment. Consider the WFS3-40P415 when 2-point teach-in, dynamic teach-in, and electrical teach-in functionality are important.

Difference in Electrical Specifications

Electrical compatibility affects installation, machine operation, and replacement planning.

Both models operate within the same nominal supply-voltage range, but their ripple specifications and current-consumption information differ.

Supply voltage

Both sensors operate between 10 V DC and 30 V DC.

This common voltage range makes them suitable candidates for many industrial DC control systems.

However, supply-voltage compatibility alone does not establish complete electrical interchangeability.

Engineers must also examine output configuration, current requirements, connector wiring, and PLC input specifications.

Residual ripple

The Leuze model specifies residual ripple from 0% to 15% of the supply voltage.

SICK specifies ripple below 10%.

The SICK specification therefore sets a tighter stated ripple limit.

This is relevant when the machine’s power supply experiences electrical fluctuations.

A stable DC supply that remains within the sensor’s specified operating conditions helps avoid unnecessary commissioning problems.

Current consumption

The manufacturers present current information differently.

Leuze specifies an open-circuit current range of 0–30 mA.

SICK specifies 20 mA without load.

These figures should not be interpreted as a direct comparison of identical measurement conditions.

The 100 mA maximum switching current is the same for both products.

Electrical connection

Both models use an M8, four-pin male connector.

This similarity may help during retrofit planning, but buyers must verify the actual pin assignments.

The SICK connection diagram identifies:

• Pin 1: Supply positive.
• Pin 2: Teach-in.
• Pin 3: Supply negative.
• Pin 4: Switching output.

The Leuze product specifies a horizontal connector outlet parallel to belt movement.

These details can affect cable routing and mounting arrangements.

Selection recommendation: Both models support 10–30 V DC and a maximum output current of 100 mA. Choose according to the PLC output requirements, ripple conditions, wiring diagram, and teach-in arrangement rather than supply voltage alone.

Difference in Protection and Operating Conditions

Industrial sensors often operate near moving label webs, packaging equipment, and production machinery. Their environmental ratings therefore deserve attention during selection.

The GS63B/6D-S8 has an IP67 protection rating, while the WFS3-40P415 has an IP65 rating.

IP67 versus IP65

The Leuze sensor provides an IP67 enclosure rating.

The SICK sensor provides an IP65 enclosure rating.

Both ratings indicate protection against dust ingress. However, their water-protection classifications differ.

IP65 indicates protection against water jets under the relevant test conditions.

IP67 includes protection against temporary immersion under specified testing conditions.

This distinction can matter in production facilities where equipment experiences regular cleaning or accidental exposure to water.

However, an IP67 rating does not automatically make a sensor suitable for every washdown process. Chemical exposure, cleaning temperature, installation orientation, cable sealing, and the complete mounting arrangement also matter.

Operating temperature

Both manufacturers specify the same operating-temperature range:

• Minimum: -20°C
• Maximum: +60°C

Consequently, neither model has a stated operating-temperature advantage over the other.

Storage temperature

The storage-temperature specifications differ.

The Leuze sensor supports storage from -30°C to +70°C.

The SICK model specifies a storage range from -30°C to +80°C.

The SICK product therefore has a 10°C higher maximum specified storage temperature.

This distinction matters mainly during transportation, warehousing, and periods when equipment remains unused.

Selection recommendation: Consider the GS63B/6D-S8 when IP67 protection is an important requirement. The WFS3-40P415 may suit installations where IP65 protection meets the environmental conditions and its higher specified storage-temperature limit is useful.

Difference in Installation and Machine Compatibility

The mechanical and electrical differences between these models can influence installation more than their common detection specifications.

A replacement sensor must fit the existing mounting arrangement and communicate correctly with the machine controller.

Installation requirements for the Leuze model

The GS63B/6D-S8 measures 11 × 30 × 80 mm and weighs 55 g.

It uses through-hole mounting, with an optional mounting device available.

Its 61 mm fork depth offers a different physical arrangement from the shorter SICK fork.

The horizontal M8 connector outlet also deserves attention. Engineers should check the available cable clearance and ensure that the connector does not interfere with moving components.

The 300 ms readiness delay should also form part of the machine-startup sequence.

Installation requirements for the SICK model

The WFS3-40P415 measures 10 × 25 × 64.3 mm and weighs approximately 36 g.

Its compact body may simplify installation in restricted spaces.

The shorter fork depth can also suit machine layouts that do not require the additional 19 mm provided by the Leuze sensor.

Its four-pin M8 connection supports the supply, PNP output, and teach-in arrangement.

The SICK model has a specified initialisation time of 20 ms. This is considerably shorter than the 300 ms readiness delay published for the Leuze model.

However, these specifications use manufacturer-specific terminology and should not be treated as identical test measurements without checking the relevant operating documentation.

Can one model directly replace the other?

Not necessarily.

Even though both models have a 3 mm fork width and 2 mm minimum label-gap specifications, their physical dimensions and electrical output arrangements differ.

Before replacing one with the other, engineers should verify:

• Available mounting dimensions.
• Fork depth and label-web alignment.
• M8 connector pin configuration.
• PLC input compatibility.
• Cable routing and connector clearance.
• Teach-in procedure.
• Startup and readiness timing.
• Environmental protection requirements.

A sensor replacement should always include mechanical and electrical verification. Matching the connector size alone is insufficient.

Difference in Industrial Application Suitability

Both products target automated label-detection requirements, but their individual specifications may make one more appropriate than the other in particular machine configurations.

The following comparison considers actual differences rather than assuming that either product is universally better.

High-speed packaging lines

High-speed packaging lines require consistent detection of closely spaced labels.

Both sensors provide a 10 kHz switching frequency and approximately 50 µs response time.

Therefore, their published switching performance is closely matched.

The more important differences concern the output configuration and installation.

The WFS3-40P415 may suit a machine with compatible PNP inputs and limited mounting space.

The GS63B/6D-S8 may suit a machine that requires a push-pull output and a 61 mm fork depth.

Automatic labelling machines

Automatic labelling machines frequently require sensor replacement, adjustment, and format changes.

The SICK WFS3-40P415 offers 2-point and dynamic teach-in, along with plus/minus adjustment buttons.

These features may help technicians when the machine requires different label settings.

The Leuze GS63B/6D-S8 provides potentiometer-based adjustment and a 20 m/min maximum conveyor speed during teach-in.

Its deeper fork may also suit particular label-path arrangements.

The final choice should depend on the machine’s existing control and mounting configuration.

Bottle labelling machines

Bottle labelling equipment may use different label materials, backing thicknesses, and gap dimensions.

Both products specify a 2 mm minimum label gap.

The Leuze model explicitly lists non-transparent label detection.

SICK specifies that its 2 mm minimum detectable object depends on label thickness.

For bottle labelling lines that use transparent films or unusual label constructions, buyers should request application-specific verification rather than assume either model will provide the required performance.

Pharmaceutical packaging equipment

Pharmaceutical packaging often requires controlled label positioning and repeatable machine operation.

Both models offer the same published switching frequency and response-time specifications.

However, their different output configurations may influence integration with the packaging machine’s PLC.

The Leuze IP67 rating may be relevant where the equipment requires its higher stated water-protection classification.

The SICK dynamic teach-in and electrical teach-in input may be useful where technicians need additional adjustment options.

Buyers should also consider the actual cleaning procedure, label stock, and machine validation requirements.

Food packaging machinery

Food packaging environments can involve cleaning activities and moisture exposure.

The IP67 rating of the GS63B/6D-S8 offers a higher water-protection classification than the IP65 rating of the WFS3-40P415.

This makes the Leuze specification worth considering when the installation requires IP67 protection.

However, neither rating independently establishes suitability for chemical washdown or high-temperature cleaning.

The equipment designer should check the complete cleaning and environmental requirements before installation.

Printing and converting equipment

Printing and converting machinery may require detection of small gaps and reliable integration with fast-moving web-handling equipment.

Both models specify a 2 mm minimum gap and 10 kHz switching frequency.

Their response-time specifications are also closely matched.

The Leuze sensor offers a 61 mm fork depth, which may suit certain web-path arrangements.

The SICK model has a smaller body and additional documented teach-in options.

Therefore, mechanical clearance, PLC compatibility, and label material should guide the selection.

Which Model Should You Choose: GS63B/6D-S8 or WFS3-40P415?

There is no universal winner in this comparison. Both products offer similar headline detection and switching specifications, but they address different mechanical and electrical requirements.

The right choice depends on how the sensor fits into the existing machine.

When should you choose Leuze GS63B/6D-S8-50128010?

• A 940 nm infrared light source.
• A multiturn potentiometer adjustment.
• Through-hole mounting.
• A 3 mm fork width.
• A minimum label gap of 2 mm.

Its deeper fork and higher enclosure protection rating represent two important differences.

The model may be particularly relevant when replacing an existing Leuze sensor or integrating a new unit into a machine designed around its dimensions and push-pull output.

Its 300 ms readiness delay should also match the machine’s startup requirements.

• A PNP switching output.
• 2-point teach-in.
• Dynamic teach-in.
• Plus/minus adjustment buttons.
• Electrical teach-in input.
• IP65 protection.
• A 20 ms initialisation time.

Its smaller dimensions and lower weight can help when installing sensors in restricted machine spaces.

The additional teach-in options may also suit production lines that frequently change label settings.

Advantages of WFS3-40P415

• Compact overall dimensions.
• Lower weight of approximately 36 g.
• PNP switching output.
• 2-point and dynamic teach-in.
• Dedicated electrical teach-in input.
• Less than 10% specified ripple.
• 20 ms initialisation time.
• Higher maximum specified storage temperature of +80°C.

Limitations of WFS3-40P415

• Shorter 42 mm fork depth.
• IP65 rather than IP67 protection.
• PNP output requires compatible PLC inputs.
• Its 2 mm detection specification includes a label-thickness qualification.
• The cited datasheet does not specify an infrared wavelength.

Final selection comparison between WFS3-40P415 and GS63B/6D-S8-50128010

The GS63B/6D-S8 is a strong candidate when the machine requires its deeper fork, push-pull output, and IP67 protection. The WFS3-40P415 deserves consideration when compact dimensions, PNP integration, and additional teach-in functionality matter more.

The best decision comes from matching the exact sensor specification to the machine’s electrical, mechanical, and environmental requirements.
