The E3ZM-LS84H 2M is an optoelectronic sensor manufactured by Omron. It provides dark-ON/Light-ON operation, PNP outputs, and a detecting range of 10mm to 200mm. It is an ultra-compact, sensitive and reliable sensor that detects both reflective and transmissive objects with a built-in lens. The device is made up of a light emitting diode (LED), amplifier, and a photoelectric receiver all housed in a small, unobtrusive package. It features a high-resolution response with a repeat accuracy of 1.2% and very high response time of 0.6 ms. The E3ZM-LS84H 2M is an ideal choice for applications such as detecting registers, gaps, holes, or bar codes.
