    The 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.
