Photoelectric sensor | Through-beam type | U-shaped | 5mm | 40x35x15mm | 10-30VDC | NO | NPN | 2m cable | PBT | Infrared LED beam | IP64
Code: PU15-TDNOThe U-shaped photoelectric sensor is a reliable solution for various automation tasks requiring precise distance object detection without direct contact. The sensor operates on the beam interruption principle: when an object passes between the infrared transmitter and receiver inside the sensor, the signal changes and generates an electrical output.
Such a sensor is widely used in automation devices, conveyor systems, packaging lines, printing equipment, and in electronics manufacturing or assembly lines where accurate detection of small objects is essential.
