Output is PNP, switching Light-ON or Dark-ON, carrying 100 mA load directly into a PLC input. Powered from 10–30 VDC and terminated with an M12 4-pin connector. The housing seals to IP67 and IP69K, so it handles high-pressure washdown in food, beverage, or heavy-wash environments. Physical footprint is 15.8 mm wide by 48.5 mm tall by 40.5 mm deep — slim enough for tight DIN-rail or bracket layouts. ## How it compares to E3FARP21F2OMS The closest peer in function is the E3FARP21F2OMS (E3FA series). Both are PNP retro-reflective with M12 connector, IP67/IP69K, 500 µs response, and 100 mA load. The key deltas are sensing distance and blanking zone: this E3S-DB sensor reaches 4.5 m versus 4 m on the E3FA, and starts sensing at 0 mm instead of 100 mm. That zero blind zone lets you mount the sensor right against the target edge — useful on a short conveyor or when the reflector is tight to the frame. The E3S-DB body is narrower at 15.8 mm versus 16.6 mm for the E3FA. If the existing panel cutout or bracket was sized for 16.6 mm, this sensor will fit with a bit of slop; if the bracket has a fixed 16.6 mm pocket, a shim or adapter clip may be needed. The 4.5 m range does give you headroom to pull the sensor back if the min distance issue arises. No rewiring required — both use the same M12 4-pin pinout and PNP logic — but the E3S-DB series has its own mounting accessories. Confirm bracket or bracket hole pattern if swapping between series.","metaTitle":"Omron E3SDBP21TOMS Retro-Reflective Sensor, PNP, 4.5 m","metaDescription":"Retro-reflective PNP photoelectric sensor, 4.5 m range, 500 µs response, M12 connector, IP67/IP69K – active production, sourced to order against RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Photoelectric Sensors"],"specifications":{"Width":"15.8 mm","title":"E3SDBP21TOMS","Height":"48.5 mm","Length":"40.5 mm","Series":"E3S-DB","Light Type":"LED, Red","Sensor Type":"Retro-Reflective Sensor","description":"Photoelectric Sensor PNP 4.5m 500us 30V 100mA LED, Red Connector, M12, 4-Pin IP67 / IP69K E3S-DB","Load Current":"100 mA","Response Time":"500 us","Switching Type":"Light-ON / Dark-ON","lifecycle_stage":"current","Termination Type":"Connector, M12, 4-Pin","Protection Rating":"IP67;IP69K","Sensing Distance Max.":"4.5 m","Sensing Distance Min.":"0 mm","Operating Voltage Max.":"30 V","Operating Voltage Min.":"10 V","Operating Temperature Max.":"60 °C","Operating Temperature Min.":"-25 °C","Optical Sensor Output Type":"PNP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$177.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/8e4693eb4cffca13491531eda96427cf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"When sourcing E3SDBP21TOMS, what's the closest functional second-source — E3FARP21F2OMS?","answer":"The E3FARP21F2OMS (E3FA series) is a close PNP retro-reflective peer, but differs in four ways: it has a 4 m instead of 4.5 m sensing distance, a 100 mm minimum sensing distance versus 0 mm, a 16.6 mm width instead of 15.8 mm, and a slightly different body length.

Mechanically, the E3S-DB body is 15.8 mm wide versus 16.6 mm for the E3FA. If the bracket or cutout was machined precisely for the wider sensor, a small shim may be needed.
