Lanbao PR18S-TM10 AC 2-Wire M18 Through-Beam Sensor Lanbao PR18S-TM10-AC 2 Wires Series is a compact M18 cylindrical through-beam photoelectric sensor set for AC industrial automation systems. It uses separate emitter and receiver units to detect opaque objects that interrupt the optical path, giving stable beam detection without requiring a reflector. This PR18S AC version is specified for 10m non-adjustable sensing distance, 20-250V AC supply, normally-open or normally-closed receiver logic depending on part number, and AC 2-wire wiring. Available variants include fixed 2m PVC cable models and E2 M12 connector models, with infrared 880nm LED light source, IP67 protection, and a PBT housing reference in the official specification table.
