SICK Retroreflective Photoelectric Sensor Block Style 100 mm to 15 m Detection Range PNP Output IP67 WL250-2P2431

SICK WL250-2P2431 is a retroreflective photoelectric sensor in a compact block sensor format, designed for industrial automation and machine vision applications. It features a visible red LED light source that detects objects within a detection range of 100 millimeters to 15 meters using retroreflective sensing technology. The sensor outputs a PNP switching signal compatible with common industrial control systems.

Powered within 10 to 30 V DC and delivering an output current up to 100 mA, this sensor supports direct driving of small loads. Its rugged ABS housing with an IP67 rating ensures full protection against dust intrusion and water jets, making it suitable for demanding and harsh industrial environments including wet or dusty conditions.

The sensor is panel mountable and equipped with a 4-pin M12 connector that can be rotated 90 degrees for flexible cable routing in tight installation spaces. The highly responsive circuitry delivers a fast response time of 500 microseconds, enabling detection at high cycle rates such as conveyor object counting or robotic pick-and-place applications.

Sensitivity adjustment is accomplished via a two-turn potentiometer with a position indicator allowing fine-tuning for different reflector types. Dual LEDs indicate both stable detection and received light strength, providing visual feedback for alignment and setup. The sensor’s electronic design incorporates reverse-polarity protection, interference suppression, and safeguards against over-current and short-circuit conditions.

This sensor is ideal for applications including presence detection of reflective labels, access control sensing in packaging machines, and assembly-line monitoring. It is supplied with a mounting bracket for easy installation.
