Omron E3ZM-R86 Photoelectric Sensor
Omron E3ZM-R86 is a connector-type retro-reflective photoelectric sensor with an M.S.R. function and supplied sensing values of 4 m [100 mm] and 3 m [100 mm]. Its 870 nm infrared LED establishes the optical path, while the PNP output communicates the switching state to compatible PLC and machine-control inputs. Light-ON or Dark-ON operation is selected by switch, and a one-turn adjuster supports setup. The sensor operates from 10 to 30 VDC, consumes up to 25 mA, and uses an M8 4-pin connector instead of fixed wiring. Operate or reset time is specified at 1 ms maximum. The E3ZM-R86 provides removable connection within the PNP MSR retro-reflective sensor range across Omron Sensor Range.

The Omron E3ZM-R86 Photoelectric Sensor uses an M.S.R. retro-reflective arrangement with supplied sensing values of 4 m [100 mm] and 3 m [100 mm]. Its 870 nm infrared LED provides the optical source, while the PNP output communicates the switching state to compatible machine-control inputs. The sensor runs from 10 to 30 VDC and consumes up to 25 mA. Load supply voltage is specified at 30 VDC maximum with load current up to 100 mA and residual voltage of 2 V maximum. A Light-ON or Dark-ON switch controls output logic, and a one-turn adjuster supports setup. Operate or reset time is 1 ms maximum. An M8 4-pin connector provides detachable wiring, while yellow operation and green stability indicators show operating status.
For an Omron PNP retro-reflective sensor where connector-based replacement is preferred over fixed cable wiring, the relevant model is the E3ZM-R86. Operating temperature is stated from -25 to 55°C, with storage extending from -40 to 70°C. Electrical protection covers reversed supply polarity, output short circuit, mutual interference, and reversed output polarity. SUS316, methacrylic resin, PES, PEEK, and fluoro rubber are listed among the supplied materials. The M8 interface provides a different installation method from the pre-wired R81 versions while retaining the supplied infrared M.S.R. arrangement. For a related PNP pre-wired version with 2 m cable connection, see E3ZM-R81 2M.
