Why Choose the Carlo Gavazzi PH18CNR65NASA Retro-Reflective Photoelectric Sensor?

The Carlo Gavazzi PH18CNR65NASA is a compact retro-reflective photoelectric sensor designed for reliable object detection in industrial automation and machine-control applications. As part of the Carlo Gavazzi PH18 series, it combines rectangular housing construction with M18 optics, providing high sensing performance in a compact format.

The PH18CNR65NASA operates by transmitting 850 nm modulated infrared light towards a suitable reflector and monitoring the returned beam. It provides a sensing range of up to 6.5 m, making it suitable for conveyors, packaging machinery, material handling and other applications requiring non-contact detection across a defined sensing path.

Operating from a 10–30 V DC supply, the PH18CNR65NASA provides complementary NPN NO+NC outputs with light and dark switching functionality. The sensor is supplied with an integral 2 m cable and features IP67 / IP69K protection together with ECOLAB suitability, supporting reliable use in demanding industrial and washdown environments.

Reliable Retro-Reflective Detection for Industrial Automation

Retro-reflective photoelectric sensing places the light transmitter and receiver in the same sensor housing and uses a reflector on the opposite side of the detection area. When an object interrupts the returning optical beam, the sensor changes its electronic output state, providing dependable non-contact detection while requiring electrical wiring on only one side of the sensing path.

The Carlo Gavazzi PH18CNR65NASA combines this practical sensing principle with complementary NPN outputs, adjustable light/dark operation and a compact industrial housing. Its high ingress protection and ECOLAB suitability make it particularly useful for automated production environments where equipment may be exposed to moisture and intensive cleaning.

Typical Applications

• Conveyor object and package detection.
• Packaging and processing machinery.
• Food and beverage production equipment.
• Material-handling and logistics systems.
• Component presence and position monitoring.
• Washdown machinery and production areas.
• PLC-controlled industrial automation systems.
