Omron E3SR86 — Photoelectric Sensors

Omron E3SR86 Photoelectric Sensor, Retroreflective PNP, 1m,

MPNE3SR86

Omron E3SR86 is a retroreflective photoelectric sensor from the E3S series, with a visible red LED beam and PNP output. It detects objects up to 1 m away using a reflector, with a 1 ms response time on M12 connector termination. Supply range is 10–30 VDC, load current 100 mA, and the housing is IP67 rated for damp or dusty areas.

Product details

Omron E3SR86 is a retroreflective photoelectric sensor from the E3S series, with a visible red LED beam and PNP output. It detects objects up to 1 m away using a reflector, with a 1 ms response time on M12 connector termination. Supply range is 10–30 VDC, load current 100 mA, and the housing is IP67 rated for damp or dusty areas.

Drop-in note vs E3SR87

Mechanical footprint is identical to the infrared E3SR87 (29.2×50 mm, M12 connector, same bracket pattern). The key delta is sensing range: E3SR86 reaches 1 m with a red beam, while E3SR87 is limited to 300 mm with infrared light. If your application needs the longer throw or a visible alignment beam, E3SR86 swaps directly onto the same mount without rewiring.

Mounting and wiring checklist

M12 connector, PNP sourcing output, 100 mA load, Light/Dark ON selectable. IP67 housing, width 29.2 mm.

Frequently asked questions

What is the closest functional second-source?

The E3SR87 is the closest peer: same mechanical dimensions, M12 connector, and PNP output, but uses an infrared beam with a 300 mm maximum range instead of the 1 m red beam. It is a mechanical drop-in but with shorter sensing distance.

What is the width of the E3SR86?

The E3SR86 has a width of 29.2 mm.

Will the E3SR86 drop into a panel specified for the E3SR87?

Yes, the mounting dimensions and M12 connector pattern are identical, so it replaces the E3SR87 without rewiring. Be mindful of the longer sensing range and red beam if the application was tuned for infrared.
