The performance characteristics of the various types of switches, there is a close to it the object element "awareness" - the displacement sensor. Utilizing displacement sensor sensitivity characteristics of the oncoming object to control the switching on or off of the object qnuo magnetic switch, which is close to the switch. [1] When an object moves close to the switch, and close to a certain distance, displacement sensors have a "perception", the switch will be action. Usually this distance is called "detection distance." Different proximity switch detection distance is also different. [2] sometimes test object is detected by a certain time interval, one by one toward the proximity switch, and one by one to leave, so constantly repeated. Different proximity switch, responsiveness of the detection object are different. This response characteristic is known as "frequency response."
