Why Choose the Carlo Gavazzi PMR10RIT Photoelectric Sensor?
The Carlo Gavazzi PMR10RIT is a robust retro-reflective photoelectric sensor with integrated time delay, designed for reliable long-distance object detection in industrial automation systems. Part of the Carlo Gavazzi PMR series, it combines infrared optical sensing, a versatile relay output and adjustable timing functionality for material handling, packaging machinery, automatic doors and general machine automation.
The PMR10RIT provides a rated switching distance of 10 m and uses 880 nm modulated infrared light. Its SPDT change-over relay output provides normally open and normally closed contacts, while selectable light-on and dark-on operation allows the switching behaviour to be configured for the application.
An integrated time-delay function adds flexibility where delayed sensor response is required. The PMR10RIT operates from a wide 10.8–264 V DC or 21.6–264 V AC supply and combines screw-terminal wiring, a 1/2-inch NPT cable entry and IP67 protection in a durable rectangular plastic housing.

Retro-Reflective Detection with Integrated Time Delay
Retro-reflective photoelectric sensing uses a sensor and separate reflector positioned opposite one another. The sensor transmits modulated infrared light towards the reflector and monitors the returned beam; when an object interrupts the optical path, the relay changes state. This arrangement provides reliable long-distance detection while requiring electrical wiring only at the sensor side.
The integrated timing capability distinguishes the PMR10RIT from the standard PMR10RI configuration. Combining a time function with an SPDT relay output allows the sensor to support applications where the control response must be delayed rather than occurring immediately when the optical state changes.

- Packaging and processing machinery.
- Automated material handling systems.
