Proximity switches, also known as non-contact proximity switch, is the ideal electronic switch sensor. When the metal detecting near-proximity switch sensing area.
Switches can be non-contact, no pressure, no spark, quickly issued electrical command,  accuracy, operating frequency, service life. Easy to install and suitable for harsh environments the ability to adjust. General mechanical limit switch can not be compared.
