Available. The SICK WTB4S-3P2231 is a compact photoelectric sensor designed for precise object detection in industrial automation applications. Operating within a sensing range of 10 mm to 120 mm, it utilizes a red LED light source with a wavelength of 650 nm to detect objects effectively. The sensor features a PNP output configuration, selectable between Light-ON and Dark-ON modes, and offers a response time of less than 0.5 milliseconds, ensuring rapid detection. It operates within a supply voltage range of 10 V DC to 30 V DC and consumes a current of 20 mA. The sensor is housed in a slim, rectangular ABS plastic casing measuring 12.2 mm in width, 41.8 mm in height, and 17.3 mm in depth, with a weight of approximately 30 grams. It is equipped with an M8 4-pin connector for easy integration into existing systems. Designed to withstand harsh industrial environments, the WTB4S-3P2231 has an ingress protection rating of IP66/IP67, indicating resistance to dust and water ingress. The sensor operates efficiently across a wide temperature range, from -40°C to +60°C, making it suitable for various industrial settings. Its adjustable 5-turn potentiometer allows for precise calibration, enhancing its versatility in diverse applications.
