That 15 m is the maximum clear-air range; real-world reach drops with dust, steam, or misalignment, so leave yourself a 20-30% margin if the environment is dirty. The NPN open-collector output sinks current to ground when the beam is broken (or made, depending on the Light ON / Dark ON switch). It's a standard three-wire DC sensor—brown to +VDC, blue to 0 V, black to the load. Selectable Light ON / Dark ON means you flip a switch on the sensor body to choose whether the output turns on when the beam is clear or when it's blocked; that saves you from having to invert the logic in the PLC.","metaTitle":"Autonics BJ15M-TDT Photoelectric Sensor, Through Beam, 15m","metaDescription":"Autonics BJ15M-TDT photoelectric sensor, through-beam infrared, 15m detection, NPN output, 12-24 VDC.
