Why Choose the Carlo Gavazzi PMP12RG Polarised Retro-Reflective Photoelectric Sensor?
The Carlo Gavazzi PMP12RG is a robust polarised retro-reflective photoelectric sensor designed for reliable long-range object detection in industrial automation, material handling and machine control applications. Part of the Carlo Gavazzi PMP series, it provides a rated operating distance of up to 12 m when correctly aligned with a suitable reflector.
The PMP12RG uses 660 nm polarised modulated red light, helping the sensor distinguish the intended reflector from unwanted reflections produced by shiny objects. Its SPDT change-over relay output provides both normally open and normally closed contacts, while selectable light/dark switching gives installers additional flexibility when configuring the sensor for different control requirements.
A wide operating supply of 10.8–264 V DC or 21.6–264 V AC enables the PMP12RG to integrate with a broad range of industrial control systems without requiring a separate low-voltage sensor supply. Screw terminals, a PG13.5 cable entry, durable rectangular plastic housing and IP67 protection make it a versatile choice for demanding industrial installations.

Reliable Long-Range Polarised Retro-Reflective Detection
Polarised retro-reflective sensing uses a sensor and separate reflector positioned opposite one another. The sensor transmits modulated red light towards the reflector and monitors the returned beam, detecting an object when that optical path is interrupted. Polarisation helps distinguish correctly reflected light from unwanted reflections generated by shiny surfaces, improving detection reliability in challenging applications.
The Carlo Gavazzi PMP12RG combines this sensing principle with a substantial 12 m operating distance and a versatile SPDT relay output. Its exceptionally wide AC/DC supply range, screw-terminal wiring and IP67 housing make it particularly useful for industrial installations where a robust standalone photoelectric sensor needs to interface directly with relays, contactors, PLC inputs or other control equipment.
