The Omron E3ZMLS84H2M is a photoelectric proximity sensor from the E3ZM series, with a PNP output and a visible red LED that detects objects from 10 mm to 200 mm. Its pre-wired cable and IP67 rating suit washdown environments, and the 1 ms response time handles high-speed part detection.
Same mechanics, different detection
The E3ZMT815M is often mentioned as a sibling — it shares the identical 21 x 10.8 x 32.2 mm housing, the same pre-wired PNP output, and the same voltage/load specs. The critical difference: E3ZMT815M uses infrared light for through-beam detection up to 15 m, while this LS84H2M is a reflective proximity sensor with a 200 mm red LED beam. If your panel was wired for an E3ZMT815M, the LS84H2M will physically fit and the wiring matches, but the sensing range and detection principle are completely different — verify your application needs short-range proximity before swapping.
