1 year warranty
The SICK WTB27-3P2441 is a compact photoelectric proximity sensor from the W27 product family, designed for diffuse reflection sensing with background suppression. It employs a visible red LED light source at 660 nm wavelength for reliable object detection across a sensing range of 30 mm to 1,100 mm. The sensor features PNP complementary switching output with light/dark switching capability, and offers potentiometer-based sensitivity adjustment for precise detection of multi-colored objects. Built in a rectangular ABS plastic housing with IP69K enclosure rating, it provides robust performance in harsh industrial environments with operating temperatures from -40°C to +60°C. The M12 4-pin male connector ensures easy installation and integration into automation systems. With a fast response time of 1.5 ms and switching frequency up to 350 Hz, the sensor is well-suited for high-speed detection applications in manufacturing, material handling, packaging, and general industrial automation.
