It outputs NPN with a 50 mA load rating and a 4 µs response time, which is the figure that decides whether it can keep up with high-speed indexing — through-beam housings of this class are typically used for part-present detection, edge counting, and encoder-style timing on small-part feeders and tape-and-reel conveyors. ## Fork housing, PCB-pin termination The body measures 5 mm wide by 10 mm high by 13.7 mm long with PCB-pin termination, so it sits on a through-hole board footprint rather than a panel-cutout — the fork straddles the target as the part passes through the slot, and the slot width itself is the optical gap. Operating temperature runs from -25 °C to 85 °C, covering typical unconditioned enclosure environments on packaging machinery and small automation cells without additional thermal planning.","metaTitle":"Omron EE-SX1081 Fork Light Barrier, 5 mm, NPN, PCB","metaDescription":"Omron EE-SX1081 transmissive photomicrosensor, 5 mm fork, NPN output, 4 µs response, 50 mA load, PCB pins.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Photoelectric Sensors"],"specifications":{"Width":"5 mm","title":"EE-SX1081","Height":"10 mm","Length":"13.7 mm","Series":"EE-SX","Sensor Type":"Fork Light Barrier","description":"Transmissive Photomicrosensor NPN 5mm 4us 50mA PCB Pins EE-SX","Load Current":"50 mA","Response Time":"4 us","lifecycle_stage":"current","Termination Type":"PCB Pins","Sensing Distance Max.":"5 mm","Operating Temperature Max.":"85 °C","Operating Temperature Min.":"-25 °C","Optical Sensor Output Type":"NPN"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.32 – $18.80","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/8c7329dd4af90da595e7bd04392e5337.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will EE-SX1081 drop into a panel that was specified around E3SCR66OMS without rewiring?","answer":"No — the E3SCR66OMS is a retro-reflective sensor with an M12, 4-pin connector and a metre-class sensing range, while the EE-SX1081 is a fork light barrier with PCB pins and a 5 mm fixed slot.
