Lanbao PR18S-DM3 DC M18 Retro-Reflective Sensor Lanbao PR18S-DM3 Series is an M18 cylindrical retro-reflective photoelectric sensor for DC industrial automation systems. It provides 3m adjustable sensing distance with a reflector reference, with NPN or PNP output and NO, NC, or NO+NC logic depending on the selected part number. This listing covers PR18S-DM3 DC variants, including fixed 2m PVC cable versions and E2 M12 connector versions. The series uses an infrared 880nm light source, PBT housing, IP67 protection, and 10-30V DC supply for compact reflector-based object detection.
