Why Choose the Carlo Gavazzi PH18CNP50NASA Polarised Retro-Reflective Photoelectric Sensor?
The Carlo Gavazzi PH18CNP50NASA is a compact and robust polarised retro-reflective photoelectric sensor designed for reliable object detection in industrial automation and machine control applications. As part of the Carlo Gavazzi PH18 photoelectric sensor series, it combines a space-saving square/M18-style housing with a sensing range of up to 5 m when used with a suitable reflector.
The PH18CNP50NASA uses 625 nm polarised modulated red light to provide dependable detection while helping reduce false switching caused by reflective objects. Its NPN complementary NO+NC outputs provide both normally open and normally closed switching signals, while light/dark switching and adjustable sensitivity make the sensor flexible for a wide variety of machinery and production applications.
Operating from a 10–30 V DC supply, the PH18CNP50NASA is supplied with a 2 m fixed cable for straightforward machine wiring. Its compact approximately 15 × 31.5 × 35 mm plastic housing provides IP67 and IP69K protection, while ECOLAB suitability makes the sensor particularly useful in industrial environments where equipment may be exposed to intensive cleaning procedures.

Reliable Polarised Detection for Industrial Automation
Polarised retro-reflective photoelectric sensors transmit light towards a separate reflector and monitor the returned beam. An object is detected when it interrupts this optical path. The polarisation system helps distinguish light returned by the intended reflector from direct reflections produced by shiny objects, reducing the possibility of false detection in applications involving reflective surfaces.
The Carlo Gavazzi PH18 series combines this dependable sensing principle with compact construction suitable for machinery where installation space is restricted. The PH18CNP50NASA adds complementary NPN outputs, adjustable sensitivity, a 2 m cable and robust IP67/IP69K protection, providing a versatile sensing solution for modern industrial automation and demanding processing environments.

- Industrial conveyors and material handling systems.
- Packaging and production machinery.
- Food and beverage processing equipment.
- Object presence and position detection.
- Product counting and monitoring systems.
- Detection applications involving shiny or reflective objects.
- Washdown machinery and processing environments.
