When the metal detection body approaches the sensing area of the switch, the switch can quickly issue electrical commands without contact, pressure, sparks, and accurately reflect the position and travel of the moving mechanism. Even when used for general travel control, its positioning, operating frequency, service life, convenience of installation adjustment, and adaptability to harsh environments are incomparable to general mechanical travel switches. It is widely used in industries such as machine tools, metallurgy, chemicals, light textiles, and printing. In automatic control systems, it can be used as a limiting, counting, positioning control, and automatic protection link. Performance characteristics: Among various switches, there is one type that has an impact on objects that are close to it; lquo; Perception; rquo; Components of Ability; mash;&mash; Displacement sensor. The use of displacement sensors to control the characteristics of approaching objects to achieve the purpose of switching on or off is called proximity switches. When an object moves towards the proximity switch and approaches a certain distance, the displacement sensor will only be activated; lquo; Perception; rquo;， The switch will only activate. Usually, this distance is called& lquo; Detection distance; rquo;。 But different proximity switches also have different detection distances. Sometimes the object being tested is moved towards the proximity switch one by one at a certain time interval, and then left one by one, repeating this process continuously. Different proximity switches have different response capabilities to the detected object. This response characteristic is called& lquo; Response frequency; rquo;。 Jiangsu Changzhou EH8-G18-A2 two-wire normally closed proximity switch AC220 for spot sale; Cementifier_ Acousto optic Uniter-CK-400_220VAC
