SICK Background Suppression Photoelectric Sensor, Block Sensor, 20 mm to 350 mm Detection Range, PNP Output WTB12-3F2431

SICK WTB12-3F2431 Background Suppression Photoelectric Sensor is a block-style sensor engineered for accurate and reliable detection used primarily in automation and control applications. It features a detection range from 20 mm to 350 mm and utilizes PNP output. This sensor is housed in a robust metal casing which provides resistance to harsh industrial environments and meets ingress protection ratings of IP66, IP67, and IP69K, making it suitable for wet, dusty, and washdown conditions.

Equipped with superior application-specific integrated circuit (ASIC) technology, it offers resistance against optical interference. The PinPoint LED produces a bright, small, and precise light spot that simplifies sensor alignment and guarantees detection accuracy even for transparent or difficult-to-detect objects.

The sensor supports panel mounting via its sturdy metal housing and uses a 4-pin M12 terminal for electrical connections. Operating parameters include a maximum DC voltage of 30 V and maximum current of 100 mA. It functions efficiently across a wide temperature range from -40°C up to 60°C, with a fast response time of 300 microseconds, enabling high-speed automation tasks.

Advanced integration is facilitated by IO-Link capabilities for full process control, from commissioning to maintenance. Its rugged construction combined with best-in-class optical components ensures a long operational life with minimal downtime.
