Fit and function
The E3Z-R86 is a polarized retroreflective photoelectric sensor in Omron's compact E3Z family, sensing from 100 mm to 3 m using a red LED. The polarization filter lets it detect shiny or mirror-like targets that would fool a standard retroreflective eye — consistent detection on glossy packages or machined metal surfaces. The connector termination keeps panel wiring clean and speeds sensor swaps: unplug the mating cable rather than untwist terminals.
How it sits against prewired alternatives
Compared to the E3S-CR61 (retroreflective, NPN/PNP, 3 m, prewired with 2 m cable), the E3Z-R86 trades the pigtail for a connector — a feature that matters when you wire a cabinet with pre-terminated M8 or M12 drops. The E3S-CR61 gives you selectable light-on/dark-on on both outputs, while the E3Z-R86's output configuration is set at the factory; confirm your signal polarity needs before committing the BOM line. The E3ZM-R61 2M adds stainless steel housing and IP69K for washdown zones, but it ships prewired and is NPN-only. If your panel uses quick-disconnects and you don't need secondary output selection, the E3Z-R86 is the cleaner install.
