Proximity switch is widely used

- May 11, 2018 -

The proximity switch is a position switch that can operate without mechanical contact with the moving part. When the object approaches the sensing surface of the switch to the action distance, the switch can be actuated without mechanical contact and exerting any pressure, thereby driving the DC electric apparatus. Or provide control instructions to a plc device. Proximity switch is a kind of switch type sensor (namely non-contact switch). It has both the characteristics of limit switch and micro switch, and it has the sensing performance, reliable operation, stable performance, fast frequency response, long service life, and anti-interference. Strong ability, and with waterproof, shockproof, corrosion-resistant and other characteristics. Products are inductive, capacitive, Hall, AC, DC type.


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 be contactless, no pressure, no spark, quickly send electrical instructions, accurately reflect the position and stroke of the moving mechanism, even if used for general stroke control, positioning accuracy, operation The frequency, the service life, the convenience of installation and adjustment, and the applicability to harsh environments cannot be compared with the general mechanical type of travel switch. It is widely used in machine tools, metallurgy, chemical, textile and printing industries. In the automatic control system can be used as limit, counting, positioning control and automatic protection links.
