Lanbao PSE-YC25 DC Background Suppression Sensor Lanbao PSE-YC25 Series is a compact little-square background-suppression photoelectric sensor for DC automation systems. It is designed for 0.2-25cm adjustable sensing, helping detect the target object while reducing unwanted switching from background surfaces behind the set detection point. This listing covers PSE-YC25DNBR, PSE-YC25DPBR, and their E3 M8 connector versions. The series uses a red 630nm light source, 5-turn distance adjustment, NPN or PNP output, NO/NC output logic, 10-30V DC supply, IP67 protection, and either a 2m PVC cable or M8 4-pin connector depending on the selected variant.
