Description
The SICK WTT12L-B2542 Photoelectric Proximity Sensor is a high-performance laser-based proximity sensor designed for industrial automation applications. This sensor utilizes time-of-flight (ToF) technology with a Class 1 visible red laser source, providing reliable object detection with a sensing range of 100 mm to 1,800 mm. Featuring background suppression function and compact design, it offers precise detection of objects regardless of surface color or reflectivity. With M12 5-pin connector, IP67 protection rating, and operating temperature range from -35°C to +50°C, this sensor is suitable for harsh industrial environments. It supports both PNP and NPN output configurations and provides fast response times for high-speed applications.
