The Omron E3S-AR86 is a retroreflective photoelectric sensor in the E3S-A block style, good for 2 meters of sensing range. It's a PNP output unit with Dark-ON/Light-ON selectable via wiring. The light source is red (700 nm). Response time is 500 µs—fast enough for most part-present, conveyor, or position checks. Power supply is 10 to 30 VDC, connector termination. Ingress protection is NEMA 4X and IEC IP67, so it stands up to washdown, dust, and grime. The adjustment uses a two-turn endless adjuster with an indicator—easy enough to dial in on a ladder or rail.

Frequently asked questions
Will E3S-AR86 drop into a panel that was specified around E3S-AR66 without rewiring?
No. Both sensors have the same mechanical dimensions, connector, and electrical supply. But the E3S-AR66 is NPN output, while E3S-AR86 is PNP. You must rewire the output side to match the logic.
