Why Choose the Carlo Gavazzi PH18CNP50NAT1SA Photoelectric Sensor?
The Carlo Gavazzi PH18CNP50NAT1SA is a compact and robust polarised retro-reflective photoelectric sensor designed for reliable non-contact object detection in industrial machinery, packaging equipment and automated handling systems. As part of the Carlo Gavazzi PH18 photoelectric sensor series, it combines a space-saving square/M18 mounting format with dependable optical performance for demanding automation applications.
The PH18CNP50NAT1SA provides a sensing range of up to 5 m and uses 625 nm polarised modulated red light to detect objects between the sensor and a suitable reflector. Its NPN complementary NO+NC outputs and selectable light/dark switching provide flexible integration with PLCs, controllers and other industrial automation equipment.
With a 10–30 V DC supply, adjustable sensitivity and an M12 pigtail connection, the PH18CNP50NAT1SA is engineered for straightforward machine installation. Its reinforced plastic housing provides IP67 and IP69K protection, while ECOLAB suitability makes the sensor particularly useful in applications requiring robust washdown-resistant sensing equipment.

Reliable Polarised Detection for Industrial Automation
Polarised retro-reflective photoelectric sensors transmit a light beam towards a reflector and monitor the returning light. When an object interrupts the optical path, the sensor changes its output state. Polarisation helps prevent highly reflective target surfaces from being mistaken for the reflector, supporting dependable detection in machinery handling shiny or reflective products.
The Carlo Gavazzi PH18 series combines this sensing principle with a compact square/M18 housing and flexible industrial connections. The PH18CNP50NAT1SA adds complementary NPN outputs, adjustable sensitivity, an M12 pigtail and high environmental protection, making it suitable for reliable detection across a broad range of automated production equipment.
Typical Applications
- Packaging and bottling machinery.
- Conveyor object and package detection.
- Food and beverage processing equipment.
- Automated material handling systems.
- Part presence, counting and position detection.
- Washdown machinery and production environments.
- OEM automation systems and machine building.
