SICK WTB11-2P2431 Photoelectric Sensor
Product Overview
The SICK WTB11-2P2431 is a compact industrial photoelectric sensor designed for reliable, non-contact object detection. It uses visible red LED light and background suppression technology to detect objects at distances of 20 mm to 350 mm. This helps distinguish the target object from the background and supports dependable operation in automated production environments.
The sensor features a PNP switching output, adjustable sensing distance and light-on/dark-on switching modes. Its compact housing, M12 connector and robust protection ratings make it suitable for packaging machinery, conveyor systems, material handling and industrial automation applications.
