Why Choose the Carlo Gavazzi PA18CRR50PASA Photoelectric Sensor?
The Carlo Gavazzi PA18CRR50PASA is a compact and dependable radial retro-reflective photoelectric sensor designed for non-contact object detection in industrial machinery and automation systems. As part of the Carlo Gavazzi PA18 series, it combines an industrial-standard M18 cylindrical plastic housing with radial optics for applications where the sensing direction needs to be perpendicular to the sensor body.
The PA18CRR50PASA uses 850 nm modulated infrared light with a separate reflector to detect objects crossing the optical path. Complementary PNP NO+NC outputs provide both normally open and normally closed switching functions, while selectable light/dark switching and adjustable sensitivity offer flexibility when commissioning the sensor for different targets and operating conditions.
With a sensing range of up to 5 m, a 10–30 V DC supply, an integral 2 m cable and IP67 / IP69K protection, the PA18CRR50PASA provides a versatile sensing solution for conveyors, packaging equipment, production machinery and demanding industrial environments.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensors transmit a light beam towards a reflector mounted opposite the sensor. The reflector returns the beam to the receiver, and an object is detected when it interrupts this optical path. This principle provides reliable non-contact detection across conveyors, machine openings and automated production lines while requiring electrical wiring at only the sensor side.
The PA18CRR50PASA adds a radial optical arrangement that directs the sensing beam at a right angle to the cylindrical sensor body. Combined with complementary PNP outputs, adjustable sensitivity and high ingress protection, this makes the sensor a flexible choice for machine builders and automation engineers working with space-constrained or demanding installations.
Typical Applications
- Industrial conveyors and material handling systems.
- Packaging and production machinery.
- Object presence and position detection.
- Product counting on automated lines.
- Machine sequencing and process automation.
- Food, beverage and other demanding industrial environments.
