1042843

Overview

The SICK model 1042843 is a WTB4S-3F2265V photoelectric proximity sensor featuring background suppression. It utilizes visible red light from a PinPoint LED source with a wavelength of 650 nm. The device offers a sensing range of 10 mm to 350 mm for objects with 90% remission, and a maximum range up to 500 mm. It is designed for hygienic and washdown zones with a specialized housing.

Feature Summary

• Background suppression functionality ensures reliable detection against varying backgrounds.
• Washdown-rated housing design suitable for hygienic environments and high-pressure cleaning.
• PinPoint LED technology provides stable illumination for precise object detection.

Applications

• Detection in hygienic processing zones
• Monitoring in washdown areas
• Automated conveyor systems requiring background suppression

Procurement Notes

Verify the specific suffix codes on the product label to confirm cable length, connector type, and switching output configuration. Ensure the ordering number matches the required sensing range variant. Cross-reference the technical datasheet for environmental ratings and electrical connections before finalizing procurement to avoid compatibility issues with existing control systems.

Selection Notes

Select this sensor when background suppression is critical for distinguishing target objects from complex backgrounds. The washdown housing makes it appropriate for food and beverage or pharmaceutical applications where hygiene standards are strict. Consider the 10 mm to 350 mm operational range for medium-distance proximity tasks requiring robust environmental protection.

Part Context

This component belongs to the WTB4S series of photoelectric sensors by SICK. The series is characterized by compact designs and advanced optical technologies like PinPoint LEDs. These sensors are engineered for industrial automation, providing reliable presence detection in challenging conditions through integrated signal processing and durable construction materials.

Replacement Considerations

Check for updated part numbers within the WTB4S family that may offer improved IP ratings or different connector configurations. Verify compatibility with existing mounting brackets and cabling assemblies. Ensure any substitute maintains the same background suppression performance and washdown certification requirements.

FAQ

What is the function of the background suppression feature?

It allows the sensor to detect objects regardless of their color or reflectivity by focusing on distance rather than signal strength, ensuring consistent performance against varying backgrounds.

Is this sensor suitable for high-pressure washing?

Yes, the WTB4S-3F2265V features a washdown housing design specifically intended for use in hygienic zones and areas subject to high-pressure cleaning procedures.
