Lanbao PR18-YC M18 Background Suppression Sensor Lanbao PR18-YC Series is an M18 cylindrical photoelectric sensor with background suppression for DC automation systems. Compared with standard diffuse-reflection sensing, background suppression helps the sensor focus on the set detection distance and reduce unwanted response from objects behind the target. This listing covers PR18-YC10DPR, PR18-YC10DNR, and their E2 M12 connector versions. The series provides 10cm adjustable sensing, red LED light source, PNP or NPN output, NO+NC logic, 10-30V DC supply, nickel-copper alloy housing, and IP67 protection.
