Description

The CRJ-A18M-5APA 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 materials such as plastics, glass, liquids, and wood without physical contact. The sensor features a dedicated IC for stable operation and excellent immunity to electrical noise common in industrial environments.

Housed in a durable M18 threaded stainless steel body, this sensor is built for integration into machinery and automated production lines. It requires a 10-30V DC supply and provides a PNP transistor output, making it directly compatible with programmable logic controllers (PLCs) and other industrial control systems for tasks like level monitoring, object counting, and position verification.

Key Features

  • Capacitive sensing technology for non-metallic object detection.
  • PNP normally-open (NO) output configuration.
  • M18 x 1mm threaded SUS-304 stainless steel housing.
  • Integrated sensitivity adjustment potentiometer.
  • Red LED indicator for real-time output status.
  • Reverse polarity and output short-circuit protection.
  • High-speed response time for dynamic applications.
  • Designed for 10-30V DC operating voltage range.

Applications

  • Level monitoring in plastic or glass tanks for liquids, granules, or powders.
  • Object detection and counting on non-metallic packaging lines (food, beverage, cosmetic).
  • Presence verification of plastic components in automated assembly machinery.
  • Material level control in hoppers and supply lines for polymers or rubber granules.
  • Position limiting and end-of-travel detection for machinery handling insulating materials.

Frequently Asked Questions

What types of materials can this capacitive sensor detect?

This capacitive proximity sensor is designed primarily for detecting non-metallic objects. It can reliably sense the presence of materials such as plastics, glass, liquids, powders, wood, and paper. It is not suitable for detecting metals; for metallic targets, an inductive proximity sensor should be used.

How do I wire the PNP output of this sensor to my PLC?

Connect the sensor's brown wire to your DC power supply positive (10-30V), the blue wire to the negative/common, and the black wire (PNP output) to your PLC's digital input. The PLC input common must be connected to the power supply negative. The output switches the positive voltage to the load when an object is detected.

Can the detection sensitivity be adjusted?

Yes, this sensor includes a built-in sensitivity adjustment potentiometer. Turning the potentiometer allows you to fine-tune the detection distance and optimize performance for different target materials or to avoid false triggers from background objects or container walls.

What is the operating voltage range and electrical protection?

The sensor operates from 10 to 30 volts DC. It incorporates reverse polarity protection, safeguarding the device if the power wires are accidentally connected backwards. It also features short-circuit protection on the output transistor to prevent damage if the output is inadvertently shorted to ground.
