The Sick WTB4 Series Photoelectric Proximity Sensor is a state-of-the-art sensing solution designed for a wide range of industrial applications. This compact and durable sensor offers both PNP and NPN output types, ensuring versatility and compatibility with various control systems. Its rectangular shape and small dimensions (16 mm x 39.5 mm x 12 mm) make it an ideal choice for installations where space is at a premium.
Equipped with a PinPoint LED, the sensor provides precise detection with a visible red light, making alignment and positioning straightforward. The light spot size is optimised for consistent detection, with a diameter of approximately 7 mm at a 50 mm distance. The sensor operates within a supply voltage range of 10 V DC to 30 V DC and boasts a quick response time of less than 0.5 ms, which is critical for high-speed processes.
The WTB4-3P2161 is designed to withstand challenging industrial environments, featuring an IP67 and IP66 rating for dust and water resistance. It can operate in a wide temperature range from -40 °C to +60 °C, ensuring reliability in both cold and hot conditions. The sensor's housing is made of robust ABS plastic, and the front lens is crafted from PMMA, contributing to its overall durability.
This sensor is an excellent choice for automation tasks that require precise object detection, including small parts detection and precise positioning. Its advanced features and robust construction make it a valuable component in any automated system, contributing to enhanced efficiency and productivity.
