Why Choose the Carlo Gavazzi PH18CNR65PASA Retro-Reflective Photoelectric Sensor?
The Carlo Gavazzi PH18CNR65PASA 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 an M18 square-format plastic housing with a rated operating distance of up to 6.5 m.
The PH18CNR65PASA uses 850 nm modulated infrared light and operates with a separate reflector, such as the Carlo Gavazzi ER4 reference reflector. Its sensitivity is adjustable by potentiometer over approximately 50–650 cm, allowing the sensing system to be optimised for the installation and target conditions.
Operating from a 10–30 V DC supply, this model provides a PNP complementary NO+NC transistor output rated up to 100 mA. A fixed 2 m cable, fast 500 Hz operating frequency and IP67/IP69K protection make the PH18CNR65PASA a versatile choice for packaging, conveying, material handling and demanding washdown environments.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensing places the emitter and receiver in the same sensor housing while a reflector is installed on the opposite side of the detection area. The sensor transmits light towards the reflector and monitors the returning beam, detecting an object when that optical path is interrupted. This arrangement provides longer sensing distances than typical diffuse-reflective sensors while requiring electrical wiring on only one side of the application.
The Carlo Gavazzi PH18CNR65PASA combines a 6.5 m rated range with adjustable sensitivity, complementary PNP outputs and rapid 500 Hz switching. Its compact square housing and IP67/IP69K protection make it suitable for reliable object detection across conveyors, packaging equipment, production machinery and applications exposed to regular cleaning.
