SICK Retroreflective Photoelectric Sensor Rectangular 2 m Detection Range PNP Output IP66, IP67, IP69K WL12-3P2461

SICK WL12-3P2461 Retroreflective Photoelectric Sensor is a rugged industrial sensor designed for precise detection of small objects in automated systems. Featuring a compact rectangular shape with a metal housing, this sensor withstands harsh environments with IP66, IP67, and IP69K ingress protection. It operates on a maximum DC voltage of 30 V and draws up to 100 mA of current, providing reliable performance across a temperature range from -40°C to 60°C.

The sensor uses an LED light source in a retroreflective detection mode to identify objects up to 2 meters away. Its PNP output type simplifies wiring integration via the industry-standard M12 4-pin connector. Threaded mounting ensures a secure mechanical fit within industrial conveyor systems, robotic end-effectors, packaging machines, and assembly lines.

With a fast response time of 330 microseconds, the sensor supports rapid proximity detection necessary for modern manufacturing and quality inspection processes. Compliant with UL safety approvals (NRKH.E181493 and NRKH7.E181493), it meets stringent industry standards. The robust ingress protection rating further allows it to resist dust ingress, water jets, immersion, and high-pressure washdowns, ensuring durability in demanding plant environments.

This sensor is suitable for various industrial, manufacturing, and automation applications including conveyor small-part presence detection, pick-and-place verification on assembly lines, object counting in packaging, proximity triggering for robot end-effectors, and fast switching inspection stations.

The metal housing ensures durability for harsh industrial environments. Threaded mounting enables secure and straightforward installation. M12 4-pin connector provides standard electrical interface for easy integration. Operates over a wide temperature range from -40°C to 60°C for versatile applications.

Fast response time of 330 microseconds for rapid detection tasks. Maximum DC voltage rating of 30 V with 100 mA maximum current draw. Detects small objects using LED illumination in a retroreflective configuration. Certified to UL safety standards under files NRKH.E181493 and NRKH7.E181493.
