Lanbao PTE-PM5S Polarized Relay Photoelectric Sensor Lanbao PTE-PM5S Series is a big-square polarized retroreflective photoelectric sensor for automation systems that need longer detection range, visible alignment, and relay output in a compact plastic housing. It is designed around 5m adjustable reflector-based sensing, making it easier to detect targets across a defined path while keeping the emitter and receiver in one sensor body. This listing covers PTE-PM5SK and PTE-PM5SK-E5 variants. The series uses a visible red LED beam for alignment, relay output for flexible control-panel integration, and 24-240V AC/DC supply for installations where a transistor-output DC sensor is not the preferred choice.
