Why Choose the Carlo Gavazzi PA18CAP50PASA Photoelectric Sensor?
The Carlo Gavazzi PA18CAP50PASA is a compact and robust polarised retro-reflective photoelectric sensor designed for reliable object detection in industrial automation, material handling and machine control systems. As part of the Carlo Gavazzi PA18 series, it combines long-range optical sensing with a space-saving M18 cylindrical housing.
The sensor uses polarised red modulated light with a suitable reflector to detect objects passing through its optical path. Polarisation helps distinguish the reflector from reflections caused by shiny objects, while complementary PNP outputs provide both normally open and normally closed switching functions for flexible control system integration.
With a sensing range of up to 5000 mm, a 10–30 V DC supply, PNP NO + NC outputs and an integral 2 m cable, the PA18CAP50PASA is well suited to conveyors, packaging machinery, food and beverage equipment and general factory automation.

Reliable Photoelectric Detection for Industrial Automation
Polarised retro-reflective photoelectric sensors transmit light towards a reflector and monitor the returned beam. When an object interrupts the optical path, the sensor changes its output state, enabling control systems and PLCs to detect products, components and materials without physical contact.
The PA18CAP50PASA combines long sensing distance with complementary PNP outputs and a rugged compact housing. Its IP67 and IP69K protection ratings make it particularly useful in industrial areas exposed to dust, moisture, cleaning processes and high-pressure washdown.
Typical Applications
- Conveyor object and package detection.
- Packaging and bottling machinery.
- Food and beverage processing equipment.
- Material handling and logistics systems.
- Textile production machinery.
- Product counting and presence detection.
- Industrial automation and machine building.
