Description

The CRJ-A12-5ANA capacitive proximity sensor operates by generating an electrostatic field and detecting changes in capacitance caused by the presence of a target object. This allows for reliable detection of non-conductive materials such as plastics, glass, wood, and liquids without physical contact.

Engineered for industrial environments, the sensor features a robust M12 threaded stainless steel housing, built-in polarity and short-circuit protection, and a dedicated IC for enhanced noise immunity. Its fast response time and high repeatability make it suitable for precise positioning, level monitoring, and counting tasks in automated machinery.

Key Features

  • Capacitive sensing technology for non-metallic object detection.
  • NPN (sinking) output configuration for standard industrial control interfaces.
  • M12 x 1 threaded barrel design for secure mechanical mounting.
  • Integrated sensitivity adjustment potentiometer for fine-tuning detection.
  • Red LED provides clear visual indication of switching state.
  • Dedicated IC ensures stable operation with excellent electromagnetic interference (EMI) resistance.
  • Built-in protection against reverse polarity and output short-circuits.
  • High-reliability construction for long-term operation in industrial settings.

Applications

  • Level monitoring of non-metallic materials in hoppers, silos, and tanks (plastics, grains, powders).
  • Presence detection of plastic bottles, containers, or packaging on conveyor lines.
  • Counting and positioning of non-conductive parts in assembly automation.
  • Liquid level detection in process tanks and reservoirs.
  • Material handling and sorting systems for food, beverage, and pharmaceutical industries.

Frequently Asked Questions

What types of materials can this capacitive sensor detect?

This capacitive proximity sensor is designed to detect non-metallic objects, including plastics, glass, wood, cardboard, liquids, and granular materials. It detects changes in the dielectric constant of the target material within its electrostatic field.

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

The NPN output is a sinking configuration. Connect the sensor's brown wire (+V), blue wire (0V/GND), and black wire (output signal) to your DC power supply and PLC input module according to the datasheet. The output switches to 0V (ground) when an object is detected. Ensure your controller's input is compatible with a sinking (NPN) signal.

What is the typical operating voltage range for this sensor?

While not explicitly stated in the provided data, standard industrial NPN capacitive sensors like this typically operate from 10-30V DC. Always verify with the official Pro-Range datasheet for the CRJ-A12-5ANA model before connecting power to ensure correct voltage application and avoid damage.

Can the detection sensitivity be adjusted?

Yes, this sensor features a built-in sensitivity adjustment potentiometer. This allows you to fine-tune the detection field to optimize performance for specific materials, container walls, or to ignore background interference, ensuring reliable object detection in your application.
