Why Choose the Carlo Gavazzi PA12B2T20NC Photoelectric Sensor?

The Carlo Gavazzi PA12B2T20NC is a compact through-beam photoelectric receiver designed for reliable object and access detection in industrial automation and safety-related applications. Part of the Carlo Gavazzi PA12 Series, this Code 2 receiver uses infrared light and works with the corresponding through-beam transmitter to provide dependable detection over distances of up to 20 m.

The PA12B2T20NC operates from a 10–30 V DC supply and provides an NPN normally closed (NC) output with dark-switching operation. Its cylindrical threaded M12 housing allows straightforward mounting in machinery, gates and automation equipment, while the integral 5 m cable simplifies connection without requiring a separate sensor connector.

With a robust metal housing and IP67 ingress protection, the PA12B2T20NC is engineered for demanding industrial environments. The receiver is specified as ESPE Type 2 and is designed for applications associated with standards including EN 12445, EN 12453, EN 12978 and UL 325, making it particularly suitable for industrial doors, gates and access-control systems.

Key Advantages

  • Reliable through-beam photoelectric receiver for industrial detection applications.
  • Long 20 m sensing range when used with the corresponding transmitter.
  • NPN normally closed output for integration with compatible control circuits.
  • 10–30 V DC supply suits common industrial control voltages.
  • Compact M12 cylindrical threaded housing simplifies sensor mounting.
  • Integral 5 m cable provides convenient machine wiring.
  • IP67 protection supports reliable use in dusty and wet environments.
  • ESPE Type 2 configuration for compatible safety-related detection applications.

Key Features

  • Carlo Gavazzi PA12 Series photoelectric sensor.
  • Code 2 through-beam receiver.
  • 20 m maximum sensing range.
  • Infrared light sensing technology.
  • NPN switching output.
  • Normally closed (NC) output function.
  • Dark-switching sensing mode.
  • 5 m integral cable connection.
  • Robust metal cylindrical threaded housing.
  • IP67 environmental protection.

Reliable Through-Beam Detection for Industrial Automation

Through-beam photoelectric sensing uses a separate transmitter and receiver positioned opposite one another. An object is detected when it interrupts the infrared beam travelling between the two devices. This arrangement provides a long sensing distance and reliable object detection, making through-beam sensors suitable for industrial machinery, automated handling equipment and access systems.

The Carlo Gavazzi PA12 Series combines this sensing principle with a compact M12 housing that can be installed where larger photoelectric sensors may be impractical. The PA12B2T20NC receiver's NPN NC output, wide DC supply range, long sensing distance and IP67 construction support dependable integration into industrial control and monitoring systems.

Typical Applications

  • Industrial doors and automated gates.
  • Machine access and presence detection systems.
  • Conveyors and material handling equipment.
  • Packaging and production machinery.
  • Object detection across extended distances.
  • Warehouse and logistics automation.
  • Industrial automation and control systems.
