Feature: 1. Proximity switch is a kind of switch-type sensor that is non-contact switch, which has the characteristics of travel switch and micro-switch with reliable action and stable performance. 2. Supporting fast frequency response for long application life, the switch has strong anti-interference ability, etc. And it also has the characteristics of waterproof, shockproof, corrosion resistance, etc. 3. When the metal detector is close to the sensing area of ​​the switch, the switch can be contactless, no pressure, no spark, which can quickly send out electrical instructions and accurately reflect the position and travel of the movement mechanism. 4. Even if it is used for general travel control, its positioning accuracy, operating frequency, service life, ease of installation and adjustment, and ability to apply to harsh environments are incomparable by general mechanical trip switch. 5. It is widely used in machine tool, metallurgy, chemical, light textile and printing industries. Furthermore, it can be used for limiting, counting, positioning control and automatic protection in automatic control systems.
