Why Choose the Carlo Gavazzi PA18CAP50NAM1SA Photoelectric Sensor?

The Carlo Gavazzi PA18CAP50NAM1SA is an axial polarised retro-reflective photoelectric sensor designed for dependable object detection in industrial automation. Part of the Carlo Gavazzi PA18 Series, it combines a compact M18 cylindrical format with a sensing range of up to 5000 mm, making it suitable for conveyors, packaging machinery and automated material-handling equipment.

The PA18CAP50NAM1SA operates from a 10–30 V DC supply and provides NPN complementary NO + NC outputs, supporting both light and dark switching. Its 625 nm polarised red light helps reject reflections from shiny objects that can cause false detection with conventional retro-reflective sensors, while adjustable sensitivity enables optimisation for the installation.

The sensor is housed in a compact M18 cylindrical threaded plastic body and features a 4-pin M12 plug for convenient connection and replacement. With IP67 and IP69K protection, ECOLAB suitability and an operating temperature range of -25 to +60 °C, the PA18CAP50NAM1SA is engineered for reliable use in demanding industrial environments.

Key Advantages

  • Polarised retro-reflective sensing provides reliable object detection using a separate reflector.
  • Long sensing range of up to 5000 mm.
  • NPN complementary NO + NC outputs provide flexible control-system integration.
  • Supports both light-ON and dark-ON switching.
  • 625 nm polarised red light improves discrimination of reflective targets.
  • Adjustable sensitivity enables accurate application setup.
  • 4-pin M12 plug supports quick installation and sensor replacement.
  • IP67 / IP69K protection and ECOLAB suitability support demanding industrial applications.

Reliable Polarised Retro-Reflective Detection

A polarised retro-reflective photoelectric sensor contains both the emitter and receiver in one housing and operates with a reflector installed opposite the sensor. The polarising optical system helps the receiver distinguish light returned by the reflector from unwanted reflections produced by shiny or highly reflective objects, improving detection reliability in challenging automation applications.

The Carlo Gavazzi PA18CAP50NAM1SA combines this sensing principle with a long 5 m range, complementary NPN outputs, adjustable sensitivity and a compact M18 body. Its M12 connection and high IP67/IP69K environmental protection make it a practical solution for machine builders requiring accurate optical sensing and straightforward sensor replacement.

Typical Applications

  • Conveyor object and product detection.
  • Packaging and processing machinery.
  • Automated assembly equipment.
  • Material handling and sorting systems.
  • Detection of shiny or reflective products.
  • Product counting and position monitoring.
  • Warehouse and logistics automation.
  • Industrial machinery requiring robust optical sensing.
