Retro-reflective washdown sensor for automated lines
The Omron E3ZMB86T is a retro-reflective photoelectric sensor from the E3Z series, with PNP output and a sensing range of 100–500 mm using a red LED. It's built for presence detection in automated lines where hygiene matters — the housing carries both IP67 and IP69K ratings, meaning it survives high-pressure hot-water washdown and chemical cleaning common in food and beverage processing. Response time is 1 ms. Termination is via M8 connector.
Both sensors are PNP, roughly the same footprint (10.8 vs 11 mm wide, 31 mm height), and share the E3Z series mechanical heritage. The critical difference is sensing method: the E3ZMB86T is retro-reflective (needs a reflector), while the E3Z-D82 is diffuse (detects direct reflection from the target). That changes what you mount opposite the sensor. Termination also differs — the E3ZMB86T uses a discrete M8 connector, while the E3Z-D82 comes with a 2 m pigtail cable. If your panel is wired for a cable, you'll need a mating cordset or a re-termination. The IP69K rating on the E3ZMB86T means it's the logical pick if washdown exposure is part of the application; the E3Z-D82 is only IP67.
