What the 7 m range means on the line
The WLF18-3V930: A 7 m sensing range covers most conveyor lanes, pallet-accumulation sections, and automated guided vehicle approaches. For a retro-reflective sensor, that range is achieved with a reflector mounted opposite the emitter — no separate receiver wiring, just one sensor head and a passive reflector. It's the go-to pick for medium-distance presence detection where you don't want to run cable to both ends.
