Lanbao PTB-YC200 Background Suppression Sensor Lanbao PTB-YC200 Series is a rectangular photoelectric sensor with background suppression for DC automation systems that need longer adjustable detection than compact M18 BGS sensors. It is designed for 200cm adjustable sensing, helping reduce unwanted response from objects behind the set detection point. This listing covers PTB-YC200DFBT3 and PTB-YC200DFBT3-E5 variants. The series uses a red LED light source, NPN + PNP output, NO/NC selection by button, 10-30V DC supply, ABS housing, IP65 protection, and either a 2m PVC cable or M12 5-pin connector depending on the selected model.
