Lanbao PR18-BC AC 2-Wire M18 Diffuse Photoelectric Sensor Lanbao PR18-BC-AC 2-Wire Series is an M18 cylindrical diffuse-reflection photoelectric sensor for AC control systems that need simple two-wire object detection. It supports 10cm non-adjustable and 40cm adjustable sensing-distance options, with NO or NC output logic depending on the selected part number. This listing covers PR18-BC10ATO, PR18-BC10ATC, PR18-BC40ATO, and PR18-BC40ATC variants, plus matching E2 M12 connector versions. The series uses an infrared LED light source, nickel-copper alloy housing, IP67 protection, and either 2m PVC cable or M12 connector wiring.
