Why Choose the Carlo Gavazzi ET1820NPAS Through-Beam Photoelectric Sensor?

The Carlo Gavazzi ET1820NPAS is a robust through-beam photoelectric sensor designed for reliable non-contact object detection in industrial automation and machine control applications. As part of the Carlo Gavazzi ET series photoelectric sensors, it provides accurate detection performance using modulated infrared light technology with a durable M18 metal housing for demanding industrial environments.

This sensor features an M18 nickel-plated brass housing and an NPN transistor output with normally open and normally closed switching functions, providing flexible integration with PLCs, controllers and automation systems. The through-beam sensing method delivers reliable detection over longer distances compared with reflective sensing technologies.

With a 20 m sensing range, 10–40 V DC supply, NPN NO+NC output, infrared LED light source and IP67 protection, the ET1820NPAS is ideal for conveyors, packaging machinery, production lines and industrial automation applications.

Reliable Object Detection for Industrial Automation

Through-beam photoelectric sensors such as the Carlo Gavazzi ET1820NPAS provide reliable object detection by using a separate emitter and receiver to create a continuous optical beam. When an object interrupts the beam, the sensor provides a switching signal for automation control systems.

The ET series combines rugged industrial construction, long sensing distances and flexible output configurations to deliver dependable performance in production machinery, conveyor systems and automated equipment.

Typical Applications

  • Industrial conveyor systems.
  • Packaging machinery.
  • Production line monitoring.
  • Material handling equipment.
  • Machine automation systems.
  • Object presence detection applications.
