It also has sensing performance, reliable operation, stable performance, fast frequency response, and long application range.. The proximity sensor switch is widely used in machine tool, metallurgy, chemical, light textile and printing industries.. Inductive proximity sensor switch detector. It can be used to detect metallic ( electrically conductive ) objects.. Can be used as limit, counting, positioning control and automatic protection in automatic control system.. It does not require mechanical contacts or pressure to make the switch actuate, thereby driving DC electrical equipment..
