Description

The CRJ-A18-8ANA capacitive sensor operates by detecting changes in capacitance caused by the presence of an object within its electromagnetic field, enabling it to sense materials like plastics, liquids, wood, and glass, unlike inductive sensors which only detect metals. Its dedicated IC ensures stable operation with excellent immunity to electrical noise common in industrial environments.

Featuring a compact M18 threaded barrel design, it is engineered for easy integration into machinery for level monitoring, object counting, and position limiting applications. The sensor is built for long-term reliability in demanding settings such as packaging, food processing, and material handling systems.

Key Features

  • Capacitive sensing principle detects both conductive and non-conductive materials.
  • NPN open-collector output (sinking) compatible with 10-30V DC systems.
  • M18 x 1mm threaded barrel constructed from SUS-304 stainless steel.
  • Integrated sensitivity adjustment via built-in potentiometer.
  • Red LED provides clear visual indication of output state.
  • Reverse polarity and output short-circuit protection for enhanced durability.
  • Fast response time suitable for high-speed counting and detection tasks.
  • IP67-rated housing provides protection against dust and temporary water immersion.

Applications

  • Level detection of non-metallic materials (plastics, granules, liquids) in hoppers and silos.
  • Object presence verification and counting on conveyor belts in packaging automation.
  • Position limiting and end-stop detection in automated machinery and assembly lines.
  • Liquid level monitoring in printing machine ink tanks and chemical process containers.
  • Detection of plastic, glass, or cardboard containers in food and beverage handling systems.

Frequently Asked Questions

What types of materials can this capacitive proximity sensor detect?

Unlike inductive sensors, this capacitive model can detect both conductive and non-conductive materials. It is suitable for sensing plastics, glass, wood, liquids, granules, and packaged goods, making it ideal for level monitoring and object detection in varied industrial applications.

How do I wire the NPN output of this sensor to my PLC or controller?

The NPN output is a sinking configuration. Connect the brown wire to your DC positive supply (10-30V), the blue wire to DC negative (0V), and the black wire as the signal output to your PLC's digital input. The output switches to 0V (ground) when an object is detected.

Can the detection sensitivity be adjusted for different materials?

Yes, the sensor features a built-in sensitivity adjustment potentiometer. Turning this screw allows you to fine-tune the detection field strength, optimizing performance for different material types, sizes, or to prevent false triggers from background objects.

What is the operating voltage range and what protections are included?

The sensor operates from 10 to 30 volts DC. It includes reverse polarity protection, safeguarding the circuit if power wires are accidentally swapped, and short-circuit protection on the output, preventing damage if the output is inadvertently shorted to the supply voltage.
