Description

The CRJ-A18-8APA operates on the capacitive sensing principle, detecting changes in dielectric constant to sense the presence of non-conductive materials like plastics, glass, liquids, and granular substances without physical contact. Its dedicated IC provides stable performance with high immunity to electrical noise common in industrial environments.

Constructed with a metal housing, this sensor is built for durability in automation applications. The red LED provides clear visual indication of the output status, aiding in setup and diagnostics. It is designed for reliable long-term operation in material handling, packaging, and level control systems.

Key Features

  • PNP (sourcing) transistor output compatible with standard PLC input modules.
  • Capacitive sensing technology for detecting non-metallic objects and materials.
  • M18 x 1 threaded barrel housing for easy installation in standard mounting holes.
  • Integrated sensitivity adjustment potentiometer for optimizing detection range.
  • Polarity reverse protection and output short-circuit protection.
  • Red LED indicator provides clear on/off state visibility.
  • High reliability design with dedicated IC for excellent noise immunity.
  • Fast response time suitable for high-speed counting and positioning applications.

Applications

  • Level monitoring of non-metallic materials in hoppers, silos, and tanks (plastics, granules, liquids).
  • Object detection and counting on packaging and bottling conveyor lines.
  • Presence sensing for paper, cardboard, or plastic sheets in printing and converting machinery.
  • Limit and position sensing for automated assembly equipment handling plastic components.
  • Material interface detection in food, beverage, and pharmaceutical processing lines.

Frequently Asked Questions

What type of output does the CRJ-A18-8APA sensor have?

This sensor features a PNP (sourcing) transistor output. This means the output pin switches to the positive supply voltage when an object is detected, making it directly compatible with the common sinking input modules of Programmable Logic Controllers (PLCs) and 24V DC control systems.

What materials can this capacitive sensor detect?

The CRJ-A18-8APA is designed to detect non-metallic objects and materials by sensing changes in dielectric constant. It is effective for plastics, glass, wood, liquids, paper, and granular substances like powders or grains, making it unsuitable for detecting pure metals.

How do I adjust the sensor's sensitivity?

The sensor includes a built-in potentiometer, typically accessed via a small screw on the side of the housing. Turning this adjustment allows you to fine-tune the detection distance and optimize performance for specific materials or to avoid false triggers from background objects.

What is the required operating voltage?

The sensor operates on a standard DC voltage range of 10-30V. Ensure correct polarity when connecting: the brown wire is typically positive (+V), the blue wire is negative (0V/Common), and the black wire is the PNP output signal.
