Lanbao PSR-TM20 DC Through-Beam Photoelectric Sensor Lanbao PSR-TM20 Series is a compact DC through-beam photoelectric sensor set for automation systems that need long-distance bea m-interruption detection in a small ABS housing. It uses separate emitter and receiver units aligned across the sensing path, giving reliable object detection independent of target surface color or reflectivity. This listing covers PSR-TM20DNB, PSR-TM20DPB, and their E2 M12 connector versions. The series supports 0.3-20m through-beam sensing, infrared 850nm light source, NPN or PNP receiver output, NO/NC logic, 10-30V DC supply, IP67 protection, and either a 2m PVC cable or M12 4-pin connector.
