Description

The CRJ-A30M-10ANA capacitive sensor operates by detecting changes in capacitance caused by the presence of a target object within its active field. This non-contact method allows for reliable detection of a wide range of materials, including plastics, glass, liquids, and granular substances, without physical wear. The sensor features built-in polarity and short-circuit protection for enhanced durability in demanding industrial environments.

Engineered for continuous operation, this sensor provides a fast response time and high repeatability, making it suitable for high-speed counting, positioning, and level monitoring applications. Its M30 threaded barrel facilitates easy installation into standard mounting holes on machinery frames, tanks, and conveyor systems.

Key Features

  • NPN (Sinking) Output: Provides a switching signal compatible with common PLC input modules and DC control systems.
  • 10mm Sensing Range: Optimized for close-proximity detection of non-metallic targets.
  • M30 Threaded Housing: Durable SUS-304 stainless steel construction with IP67-equivalent sealing for dust and water resistance.
  • Advanced Noise Immunity: Utilizes a proprietary IC to ensure stable operation in electrically noisy industrial environments.
  • User-Adjustable Sensitivity: Integrated potentiometer allows fine-tuning of the detection threshold for different materials.
  • Visual Status Indicator: Red LED illuminates when an object is detected, aiding in setup and diagnostics.
  • Robust Circuit Protection: Includes reverse polarity and output short-circuit safeguards.
  • High-Speed Response: Enables reliable performance in high-cycle counting and positioning tasks.

Applications

  • Level monitoring of plastic pellets, powders, and granules in hoppers and silos.
  • Presence detection of glass or plastic bottles on packaging and filling lines.
  • Counting and positioning of non-metallic components in automated assembly systems.
  • Liquid level control in transparent or opaque tanks within chemical processing.
  • Limit switching for automated machinery where contactless operation is required.

Frequently Asked Questions

What is the operating voltage range for this NPN capacitive sensor?

The Pro-Range CRJ-A30M-10ANA sensor operates on a DC supply voltage range of 10 to 30V. It is designed to be powered directly from standard industrial 24V DC power supplies. Ensure correct polarity connection as the sensor includes reverse polarity protection.

Can this sensor detect metallic objects?

While primarily optimized for non-metallic materials like plastics, glass, and liquids, this capacitive sensor can detect metallic objects. However, its 10mm sensing distance is calibrated for dielectric materials; detection of metals may require sensitivity adjustment and could result in a shorter effective range.

How do I adjust the sensor's sensitivity?

A sensitivity adjustment potentiometer is located on the rear or side of the sensor housing. Use a small screwdriver to turn the pot: clockwise to increase sensitivity (detect objects further away) and counter-clockwise to decrease it. Adjust while observing the status LED to set the desired detection threshold.

What is the wiring configuration for the NPN output?

This 3-wire sensor has brown (V+), blue (V- / GND), and black (NPN output) leads. Connect brown to +24V DC, blue to 0V/GND. The black wire is the NPN open-collector output, which switches to ground (sinks current) when an object is detected. Connect it to your PLC input or load.

Is this sensor suitable for wet or dusty environments?

Yes, with its stainless steel M30 housing and IP67-rated sealing, the sensor is protected against dust ingress and temporary immersion in water up to 1 meter for 30 minutes. It is suitable for washdown areas, outdoor use, and industrial environments with particulate matter.
