It reaches 20 m through the gap, which covers most conveyor or portal alignments without needing a retroreflector. The NPN output sinks 100 mA and the supply is 10–30 VDC, so it talks straight to a sinking PLC input card or a relay coil without a conversion board. Rated IP67 and IP69K, the brass housing shrugs off high-pressure washdown — common in food, beverage, and car-wash tunnels. Response time is 0.5 msec, so it catches fast-moving objects at line speed. The 2 m bare-wire cable is pre-attached; if you prefer a quick-disconnect, look at the E3FB-TN21 (M12 connector) variant. ## NPB vs PNP — Same Barrel, Different Handshake The only difference between the E3FB-TN112M and the E3FB-TP112M is the output circuit: NPN vs PNP. Same 20 m range, same brass M18 body, same 0.5 ms response, same 100 mA load limit, same cable length, same IP rating. If your controller expects sourcing outputs (PNP), the TP112M drops into the same hole and the same wiring scheme — just swap the load side polarity. No mechanical rework, no new bracket. The decision is purely electrical compatibility with your input card or relay logic.","metaTitle":"Omron E3FB-TN112M Through-Beam Sensor Set, M18, NPN, 20m","metaDescription":"Active-production Omron E3FB-TN112M through-beam photoelectric sensor set.
