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, 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" EYZ60-D15MP1, 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." TCK fluxgate magnetic switch using technology to produce sensing probe, a certain frequency of the input excitation current, in the absence of a magnetic field of the permanent magnet is detected, no output signal, when the detected object (permanent magnet) moves to the detection region E, the magnetic field generator induced current, and the excitation current superimposed, generating a pulse signal, an induction coil in the pulse is input to IC processing, driving a switching transistor, so that it is turned on, starting a relay output signal. TCK-1P (common type detected magnetic signals start, delay 2 seconds after the reset signal is removed) TCK-1T (Ex-detected magnetic signals start, delay 2 seconds after the reset signal is removed) TCK-2P (ordinary type with direction detection, only the magnetic signal of the N-S direction to start a particular sport, the signal delay of 2 seconds to reset removed) TCK-2T (explosion-proof type, with direction detection, only the N-S direction of movement of the magnetic field signal specific start EYD60- D8MP1, will delay the removal of two seconds after the signal is reset) TCK-3P (common type detected magnetic signal to start, after the signal is removed to keep EIE-X18MEI, again detected magnetic reset) TCK-3T (Ex-detected magnetic signal to start, maintain signal removed again after detecting the magnetic reset) TCK-4P (ordinary type, with direction detection, only the magnetic signal of the N-S direction to start a particular exercise, keep the signal is removed, the magnetic field is detected again reset signal) TCK-4T (explosion-proof, will take direction detection, only the direction of the magnetic field signal starts to N-S-specific exercise, keep the signal is removed, it will reset again to detect the magnetic field signal) ERE-1515-10A-1 magnetic switch (certified merchants) are provided by the Shenyang Electric Co., the people.
