The Pro-Range CRJ-A18M-5ANB is an NPN-output capacitive proximity sensor with a 5mm detection range and M18 threaded housing, designed for non-contact detection of non-metallic objects in industrial automation systems, PLCs, and material handling applications.

Features

  • Capacitive sensing principle detects non-metallic objects (plastics, liquids, powders) up to 5mm.
  • NPN open-collector output compatible with PLCs and industrial control systems.
  • M18 threaded stainless steel housing for robust panel mounting.
  • Integrated sensitivity adjustment potentiometer for fine-tuning detection range.
  • Red LED status indicator and built-in short-circuit/polarity protection.

Description

The CRJ-A18M-5ANB operates on a capacitive sensing principle, detecting changes in dielectric constant to sense the presence of non-conductive materials like plastics, glass, liquids, and granular solids without physical contact. Its dedicated IC ensures stable operation with high immunity to electrical noise common in industrial environments.

Housed in a durable M18 threaded stainless steel barrel, this sensor is built for continuous operation in automation lines. It features an adjustable sensitivity screw, allowing the 5mm nominal sensing distance to be tuned for specific material types and application conditions, providing reliable detection, positioning, and counting functions.

Key Features

  • Capacitive sensing for non-metallic object detection (plastics, liquids, powders).
  • NPN (sinking) output signal for direct interface with PLC digital inputs.
  • M18 x 1mm threaded stainless steel housing with IP67-equivalent sealing.
  • Integrated sensitivity adjustment potentiometer for application-specific tuning.
  • High-noise immunity via dedicated detection IC and shielded design.
  • Red LED provides clear visual indication of detection status.
  • Built-in reverse polarity and output short-circuit protection.
  • Fast response time suitable for high-speed counting and positioning tasks.

Applications

  • Level monitoring of plastic pellets, powders, or liquids in hoppers and silos.
  • Presence detection of non-metallic packaging (bottles, cartons) on conveyor lines.
  • Counting and positioning of plastic components in automated assembly machines.
  • Material interface detection in food, pharmaceutical, and cosmetic processing.
  • Limit switching for robotic arms handling glass or ceramic materials.

Frequently Asked Questions

What types of materials can this capacitive sensor detect?

This capacitive proximity sensor is designed specifically for detecting non-metallic materials, including plastics, glass, liquids, powders, and granular solids. It senses changes in dielectric constant, making it unsuitable for direct metal detection, which is better served by inductive sensors.

What is the required wiring and power supply for the NPN output?

The sensor operates on a 10-30V DC supply. The NPN output is a sinking type (open collector); connect the brown wire to V+, blue to V-, and the black output wire to your PLC input or load. The load is then connected between the black wire and V+ to complete the circuit.

How do I adjust the sensor's sensitivity for my application?

A sensitivity adjustment potentiometer is located on the rear of the sensor housing. Use a small screwdriver to turn it clockwise to increase the detection range (more sensitive) or counter-clockwise to decrease it (less sensitive). Adjust while observing the red LED indicator with your target object in place.

Is this sensor suitable for wet or dusty industrial environments?

Yes, the stainless steel M18 housing provides a high degree of environmental sealing, typically equivalent to IP67. This makes it resistant to dust ingress and capable of withstanding temporary immersion or washdowns, suitable for food, packaging, and chemical processing lines.
