It uses a Red LED, talks PNP, and picks up a reflector at 2 m. 500 µs response keeps it fast enough for most part detection on a conveyor. M12 connector, IP67 — sealed up for washdown zones. Lifecycle is current, so I'll take the whole lot and quote you off the RFQ. ## Footprint match vs E3SAD36 — but not a straight swap But don't treat them as interchangable on the BOM: the E3SAR36 needs a reflector target (retro mode at 2 m), while the E3SAD36 fires straight at the object (diffuse, 200 mm). If your line was laid out for a retro sensor, the E3SAD36 won't pick up the reflector response — you'd be respacing the whole station. Fast nickel beats slow dime: get the right sensing method first. Lifecycle status is current — Omron is still running this variant. No last-time-buy clock ticking. Sourcing is straightforward: send the RFQ, we'll confirm availability and lead time. If you're sorting a plant-closure pallet and see a pile of E3SAR36s, the value's in the sort — they move fast to integrators who need a sealed PNP retro for a machine build.","metaTitle":"Omron E3SAR36 Retro-Reflective Sensor PNP 2m M12","metaDescription":"E3SAR36 retro-reflective photoelectric sensor from Omron E3S-A series: PNP, 2 m range, 500 µs response, IP67, M12 connector.
