This article describes the design, applications, and operating principles of industrial capacitive proximity sensors. They detect electro-conducting and non-conducting materials, soli powdered or liquid. The main difference between the two types is that capacitive proximity sensors produce an electrostatic field instead of an electromagnetic field. It is because of the technologies low-cost and versatility that it is relatively easy to apply the technology into everyday objects, an area that can be explored by using off-the-shelf materials. Find all the manufacturers of capacitive proximity sensor and contact them directly on DirectIndustry.

High temperature switches for temperatures up to 2°C are available as well. Large switching distances up to 1mm and sensors made from PTFE or PEEK, especially well-suited for the food industry, . Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.

In order to use this switch, the following must first be defined:. Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous . Adjustable sensing distance 3-mm. Thermoplastic Polyester Housing.

Automatic detection of NPN or PNP load. Teach-in of sensing distance via push-button or. Selectable make or break switching by means . Make or break switching function. CR Series features electric capacitive type proximity sensors.

Moreover, built-in sensitivity volume allows users to . The model has one normally open and one normally closed contact, and the electrical connections are made using miniature banana jacks. These sensors are often used in . I have been making more progress. Having two sensors next to each other .
