SICK Retroreflective Photoelectric Sensor Block Style 5 m Detection Range NPN Output IP66 IP67 IP68 IP69K WLG4S-3N1132V

SICK WLG4S-3N1132V is a retroreflective Photoelectric Sensor in a block style housing with stainless steel construction, offering precise detection of transparent objects up to 5 meters. This sensor features an NPN output and is rated for IP66, IP67, IP68, and IP69K ingress protection, making it suitable for harsh industrial environments.

The sensor’s PinPoint LED provides a highly visible and well-defined light spot which simplifies alignment and increases reliability even with small reflectors. It uses single-lens autocollimation technology to see through extremely transparent thin films, small gaps, and objects with lens defects. Its response time is 500 microseconds, enabling fast detection suitable for automation applications.

Designed for industrial automation, manufacturing, laboratory use, and process monitoring, the WLG4S-3N1132V is easily configured through a teach-in pushbutton or IO-Link interface. It compensates automatically for environmental changes such as temperature variations and contamination, ensuring stable performance and less downtime.

With a maximum DC voltage rating of 30V and max current of 100 mA, this sensor is built for reliability and precision. The robust stainless steel housing and multiple IP ratings provide excellent protection against dust, water, and even high-pressure cleaning.

Mounting is by threaded, through-hole type, supporting secure installation in diverse environments. The sensor is certified by UL and meets stringent hazardous area standards EN IEC 63000, making it a dependable choice for demanding industrial applications.
