What is the difference between inductive and capacitive proximity switches?

A：

Inductive proximity switches are mainly used to detect metal objects, have strong anti-interference capabilities, and are suitable for industrial automation scenarios; while capacitive proximity switches can detect metals and non-metals (such as plastics, liquids, wood, etc.), have high sensitivity, but are more easily affected by the environment. The choice should be made based on the material of the target object and the use environment.
