Why Choose the Carlo Gavazzi EO1804NPAS-1 Photoelectric Sensor?

The Carlo Gavazzi EO1804NPAS-1 is a robust M18 diffuse-reflective photoelectric sensor designed for reliable object detection in industrial machinery, conveying and automation systems. Part of the Carlo Gavazzi EO1804 series, it combines a nickel-plated brass threaded barrel housing with complementary NPN normally open and normally closed outputs for flexible integration into DC control circuits.

The EO1804NPAS-1 provides an adjustable sensing range of 0–400 mm using modulated infrared light at 880 nm. Its diffuse-reflective operating principle allows objects to be detected directly from reflected light without requiring a separate reflector or receiver, making installation straightforward across a wide range of machinery applications.

Operating from a 10–40 V DC supply, the sensor supports light-on and dark-on switching, a maximum switching frequency of 120 Hz and load currents up to 200 mA. Its M12 connector, yellow LED indication, IP67 protection and adjustable sensitivity make it particularly suitable for demanding factory automation and material handling environments.

Key Advantages

  • Reliable diffuse-reflective object detection up to 400 mm.
  • Adjustable sensitivity supports accurate setup for different targets.
  • Complementary NPN NO + NC outputs provide flexible control options.
  • Durable M18 nickel-plated brass housing for industrial environments.
  • M12 connector simplifies installation, maintenance and replacement.
  • IP67 protection supports reliable operation around dust and moisture.

Key Features

  • Carlo Gavazzi EO1804 diffuse-reflective photoelectric sensor.
  • 0–400 mm adjustable sensing range.
  • Infrared modulated light, 880 nm.
  • NPN complementary NO + NC outputs.
  • Light-on / dark-on switching.
  • 10–40 V DC rated power supply.
  • Maximum 200 mA load current.
  • Maximum 120 Hz switching frequency.
  • M18 cylindrical threaded metal housing.
  • Yellow LED output indication.
  • M12 plug connection.
  • IP67 degree of protection.

Reliable Diffuse-Reflective Detection for Industrial Automation

Diffuse-reflective photoelectric sensors transmit light towards a target and detect the light reflected directly back from the object. This allows objects to be detected without physical contact and without the separate reflector required by retro-reflective sensing systems.

The Carlo Gavazzi EO1804NPAS-1 combines an adjustable 400 mm sensing range with an M18 metal housing, complementary NPN outputs and an M12 connection. These characteristics make it a practical sensing solution for machine builders and automation engineers requiring flexible object detection in industrial production and material handling equipment.

Typical Applications

  • Conveyor object detection and counting.
  • Packaging and production machinery.
  • Material handling and transfer systems.
  • Industrial component presence detection.
  • Automated assembly equipment.
  • Factory automation and machine control systems.
