Lanbao PR18-DM3 AC 2-Wire M18 Retro-Reflective Sensor Lanbao PR18-DM3-AC 2-Wire Series is an M18 cylindrical retro-reflective photoelectric sensor for AC two-wire industrial automation circuits. It provides 3m adjustable sensing distance with a reflector reference, and supports normally-open or normally-closed output depending on the selected part number. This listing covers PR18-DM3ATO and PR18-DM3ATC AC two-wire variants, including fixed 2m PVC cable versions and E2 M12 connector versions. The series uses an infrared 880nm light source, nickel-copper alloy housing, IP67 protection, and 20-250V AC two-wire operation for reflector-based object detection. For related Lanbao photoelectric sensors, compare the Lanbao PR30-DM5 AC 2-Wire Series, Lanbao PR30-DM5 DC Series, and Lanbao PR18S-BC AC 2-Wire Series.
