The Anvantages and Features of Allen Bradley Capacitive-Proximity-Sensors

Allen Bradley Bulletin 875C and CP 875 Tubular capacitive proximity sensor offers adjustable sensing distance. It is equipped with two status indicator shows the energy and production. Shielded sensors 875C placed in a copper nickel-plated barrel. 875CP release contains plastic barrel and models unchecked. Both versions meet the NEMA 12 and IP67 (IEC 529) enclosure standards. The connection options include cable poly vinyl chloride, and small and Pico rapid disconnect.

Allen Bradley Capacitive-Proximity-Sensors

Based on the inductive proximity sensor, the default target for Allen Bradley Capacitive-Proximity-Sensors is a square piece of 1 mm (0.04 inch) mild steel thick. It is with sides of equal length to diameter on the active face or three times the nominal distance conversion, whichever is greater. Based target level according to IEC testing standards. However, you do not need to be based on the sensor achieve a reliable target in a typical application.

The Allen Bradley Capacitive-Proximity-Sensors Features, specifically designed to produce capacitive proximity to the field of electricity

There are many Tubular Capacitive Proximity Sensors features you can get, those are stated as follows:

1. Metals, nonferrous ability to solid and liquid sensor
2. Reserve Minerals (875C) and plastic model of unchecked (875CP)
3. Sensing distance Adjustable
4. 2 or 3 wire operation
5. PVC cable or quick disconnect versions
6. 10 ... 24 ... 48V DC or 240V AC
7. Output normally open or normally closed
8. Short circuit, overload, reverse polarity, protection from transient noise

Capacitive proximity sensors are similar in size, shape, and the concept of inductive proximity sensors. However, unlike inductive sensors which uses magnetic field induction to sense objects, it produces capacitive proximity to the field of electricity and interact with changes in amplitude occur when the target enters the electric field. When the goal is to be out of the electric field, the oscillator is inactive. With the approach, capacitive coupling has the development between the target and the capacitive probe. When you reach a certain amplitude threshold, the oscillator is enabled, which led to the output circuit to switch between ON and OFF states.

Allen Bradley Capacitive-Proximity-Sensors Advantages

There are many advantages you can get from of Allen Bradley capacitive proximity sensors, those are included:

1. Detects and nonferrous metals, liquids and solids
2. We can "see through" certain materials (box product)
3. Solid-state, long life
4. Many mounting configurations

The capacitive proximity is very sensitive to water, with a dielectric constant of 80 sensors. This is ideal for applications such as liquid level sensing. The same sensors, however, will not be sensitive in the air, with a dielectric constant of 1. Fall on the element the other goal within the range of sensitivity, such as wet wood, with a dielectric constant between 10 and 30, and the wood dried, between 2 and 6.


You can choose the appropriate Allen Bradley Capacitive-Proximity-Sensors products and services to meet your needs. The wide range of products and services designed to support their capacity to improve processes through every stage of your manufacturing cycle. It comes from design and installation through operation and maintenance.
