This M30 capacitive sensor detects many kinds of materials, not just metal. It's good for finding non-metal items like plastics, wood, and powders. It also works as a liquid level sensor for non-metallic containers.
Features and Benefits
- Detects All Materials - It senses changes in capacitance. This lets it find almost any object in its field. This includes metal parts, plastic bottles, and liquids.
- Adjustable Sensitivity - You can easily change the sensor's sensitivity. This fine-tunes detection for specific materials and stops false triggers.
- Flexible NPN/PNP Outputs - The M30 capacitive switch comes in NPN and PNP setups with NO/NC outputs. This ensures it works with your automation and control hardware.
- Easy Installation - It runs on a standard 10-30VDC supply. It includes a 2-meter cable. This makes wiring it into your system simple.
Applications
- Checking fill levels of grains or liquids in a plastic hopper or tank.
- Confirming cardboard boxes or plastic items are on a conveyor belt.
- Finding wood or plastic workpieces in automated processing machines.
What It Is
This is a GTRIC M30 Capacitive Sensor, designed for detecting liquid levels and non-metal targets. It operates within a 10-30V DC range and features an M30 thread size for mounting. The sensor is constructed from plastic and comes with a 2m cable. As a capacitive proximity sensor, it functions by sensing changes in an electrical field when a target enters its adjustable sensing range. It offers both Normally Open (NO) and Normally Closed (NC) output states, with NPN and PNP output types, making it versatile for various control systems.
Key Uses & Applications
This M30 capacitive sensor is primarily used for reliable detection of liquid levels in non-metallic containers, or for sensing other non-metal targets. Its adjustable sensing distance allows for fine-tuning to specific application requirements. With an IP67 protection rating, it is suitable for environments where dust and water ingress are a concern. The flush and non-flush mounting options provide flexibility during installation. It can be integrated into industrial control systems to automate processes, such as monitoring fluid levels in tanks or detecting the presence of non-metallic objects on a production line.
How to Choose
When selecting a sensor, consider the target material; this unit is for non-metal and liquid sensing. Verify the operating voltage matches your system, which for this model is 10-30V DC. The M30 thread size is a key mounting consideration. Determine if you require Normally Open (NO) or Normally Closed (NC) output, and whether NPN or PNP output type is needed for your electronics module. The adjustable sensing distance is useful for precise applications. To test a proximity sensor, connect it to a power supply and a multimeter, then introduce a target into its sensing field to observe the output change.

A: A capacitive sensor like this one is useful for detecting a wide variety of materials. It can sense metals, plastics, wood, and paper, as well as liquids and granular powders.. Q: How long is the cable that comes with the sensor? A: It comes with a 2-meter long integrated cable. The cable has a PVC jacket, which provides good resistance to oils and abrasion in a shop environment.. Q: Can I get this sensor with a PNP Normally Closed output? A: Yes, you can. We offer this sensor in both NPN and PNP versions, with your choice of either Normally Open (NO) or Normally Closed (NC) switching logic.. Q: Would this work for detecting the water level in a plastic tank? A: That's a perfect application for this sensor. You can mount it to the outside of the non-metallic tank, and it will detect the liquid inside when it reaches that level, without ever touching the fluid.. Q: Is the sensitivity adjustable, and what is the warranty? A: Yes, there's a small adjustment screw on the sensor that lets you tune the sensitivity for your specific material and application. All our sensors are covered by a one-year warranty..
