The IME18-08BPOZW2S is a photoelectric sensor manufactured by Sick. This type of sensor contains an infra-red light emitting diode, a light-sensitive semiconductor, and an amplifier. It is designed to detect objects by measuring the amount of light reflected off them. It works by sending an invisible beam of light to a target object and measuring how much of the reflected light is received. The sensor can then be used to determine the presence or absence of an object, as well as its distance, size, and speed. The IME18-08BPOZW2S is suitable for applications requiring a reliable detection system with a long detection range, including position detection, gap detection, and surface detection.
