Proximity switch is also a kind of switch. Proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, it does not require mechanical contact or any pressure to make the switch act, thereby driving DC electrical appliances. Or provide control instructions to the computer (plc) device. Proximity switch, also known as non-contact proximity switch, is an ideal electronic switch sensor. When the metal detector is close to the sensing area of the switch, the switch can quickly issue electrical commands without contact, pressure, and spark, and accurately reflect the position and stroke of the motion mechanism.
The principle of proximity switch is to place a piece of metal or semiconductor sheet with current in a magnetic field vertically, and a potential difference will be generated at the two ends of the sheet. This principle is used to control on and off.
