SICK Background Suppression Photoelectric Sensor, Block Sensor, Detection Range 20 mm to 350 mm, NPN Output WTB12-3N1131

SICK WTB12-3N1131 Background Suppression Photoelectric Sensor, part of the W12-3 series, features a robust metal housing and operates reliably within a 20 mm to 350 mm detection range with NPN output type. The sensor supports industrial automation, packaging, pharmaceutical, food and beverage, and manufacturing applications where precise object detection is critical.

This sensor delivers best-in-class optical performance using advanced OES technology and autocollimation capabilities with retro-reflective sensors. It employs a second emitter LED to suppress background and foreground interference, enhancing detection accuracy. A highly visible, small pinpoint LED spot simplifies and speeds up sensor alignment, reducing installation downtime.

The rugged die-cast zinc housing offers durability with optional Teflon® coating for added protection, meeting IP66, IP67, and IP69K ingress protection ratings. It operates in temperatures ranging from -40°C to 60°C and is rated for a maximum current of 100 mA and 30 V DC voltage, ensuring suitability for demanding industrial environments. Installation is flexible via hole and threaded mounts.

Equipped with ASIC technology, this sensor is immune to ambient optical interferences and guarantees precise switching characteristics. IO-Link communication provides easy access to sensor diagnostics, configurations, and visualization, enhancing maintenance and control integration. Quick setup is facilitated using function blocks, enabling seamless PLC integration.

Applications include board detection, ultrasonic welding station presence checking, tray position validation, collision prevention at robot grippers, cutting edge detection, paper edge detection, dynamic gap measurement with smart sensor solutions, transparent object detection, direct-marked 2D code identification, stack identification, and inline quality control.
