A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared , and a photoelectric receiver. They are largely used in industrial manufacturing. There are three different useful types: opposed (through-beam), retro-reflective, and proximity-sensing (diffused). Features: Photoelectricity is small and the resolution is extremely high. The high response speed of 5.0.1~1ms can adapt to the control needs of various packaging machines, bag-making machines, and printing machines. Excellent internal circuit design, excellent resistance to various electromagnetic and stray light interference, stable operation, and no malfunction. With a sensitivity adjustment knob, you can adjust without using tools.
