SICK Background Suppression Photoelectric Sensor, Block Sensor, 25 mm to 300 mm Detection Range, PNP Output WTB4SL-3P4162H

SICK WTB4SL-3P4162H Background Suppression Photoelectric Sensor provides highly precise object detection using a laser light spot with a detection range from 25 mm to 300 mm and PNP output type. This sensor features a robust stainless steel housing designed for hygienic and wash down use, certified with an IP69K rating for protection against water and dust ingress. Operating temperature ranges from -10°C to 50°C, enabling reliable operation in various industrial environments.

The sensor uses advanced SICK proprietary ASIC and laser technology for outstanding background suppression and ambient light immunity, minimizing incorrect switching to reduce machine downtime even under strong ambient light conditions, such as modern energy-saving lighting. It includes a teach-in pushbutton for easy switching between detection modes for transparent or tiny non-transparent objects.

Its durable stainless steel housing meets ECOLAB certification standards and is tested to IP 66, IP 67, IP 68, and IP 69K ratings, making it ideal for industries requiring strict hygiene standards such as food, pharmaceutical, and packaging production lines. The device also offers optional IO-Link support for effortless initial diagnostics and system performance monitoring.

This sensor reliably detects materials including methyl methacrylate and various plastics and is designed for use cases such as precise object positioning on conveyors, edge detection for ampulla tubes before final closing, and precise slice detection in sausage packaging. The fast response time of 500 microseconds ensures quick and accurate switching in demanding manufacturing and automation processes.

With CE and UL certifications, this model meets international safety and quality standards. The WTB4SL-3P4162H is manufactured in Germany, reflecting SICK’s commitment to product excellence and durability.
