SICK WTB4S-3P2261 Photoelectric Sensor – Background Suppression, PNP Output (1042041)

The SICK WTB4S-3P2261 is a compact, high-precision photoelectric proximity sensor featuring background suppression for reliable detection of objects regardless of color or surface finish. With a sensing range of 10 mm to 180 mm and a PinPoint red LED light source, this sensor is ideal for precise detection in confined spaces. Housed in a slim 12.2 mm ABS body, it offers robust performance, fast response times, and complementary PNP switching output for both light and dark operation.

Certified by ECOLAB, cULUS, and compliant with SICK SIRIC and PinPoint 2.0 technologies, this sensor is built for harsh industrial conditions and fast-paced production environments.
