Why Choose the Carlo Gavazzi PH18CNR65PAT1SA Retro-Reflective Photoelectric Sensor?
The Carlo Gavazzi PH18CNR65PAT1SA is a compact retro-reflective photoelectric sensor designed for reliable non-contact object detection in industrial automation and machine control applications. Part of the Carlo Gavazzi PH18 series, it combines a space-saving square M18-style plastic housing with a sensing distance of up to 6.5 m.
The PH18CNR65PAT1SA uses 850 nm modulated infrared light and works with a reflector positioned opposite the sensor. Its sensitivity is adjustable, allowing the sensing system to be optimised for different installation distances and operating conditions while retaining the convenient single-sided wiring associated with retro-reflective sensing.
Operating from a 10–30 V DC supply, this model provides a PNP complementary NO+NC transistor output with light and dark switching. The M12 pigtail connection, fast 500 Hz operating frequency and IP67/IP69K protection make the PH18CNR65PAT1SA particularly suitable for packaging, conveying, material handling, food processing and other demanding industrial applications.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensing incorporates the light emitter and receiver within the same sensor housing while a reflector is installed on the opposite side of the detection area. The emitted beam travels to the reflector and returns to the sensor, with objects detected when they interrupt this optical path. This arrangement provides long sensing distances while requiring powered equipment on only one side of the application.
The Carlo Gavazzi PH18CNR65PAT1SA combines a 6.5 m sensing range with adjustable sensitivity, complementary PNP outputs and fast switching performance. Its compact construction, M12 pigtail connection and IP69K protection make it a practical solution for machinery where reliable sensing, convenient maintenance and resistance to demanding environmental conditions are important.
