The WTB4-3N1361 is a photoelectric proximity sensor designed for reliable object detection. It features diffuse operation with background suppression, allowing it to detect objects within a range of approximately 4 to 150 millimeters. The sensor has an NPN output configuration (NPN LO) and uses a 3-wire connection with a 2-meter cable for easy integration into various systems. Its compact, rectangular housing measures 16 mm in width, 39.5 mm in height, and 12 mm in depth, making it suitable for space-constrained applications. The optical axis includes both sender and receiver components, with status indication provided by a yellow LED indicator.
