Nanjing KJT Electric Co,.LTD
Our main products are proximity sensor, photoelectric sensor,speed sensor,wireless sensor and so on.
The KJT-EV58S25-LY series Variable Reluctance Speed (VRS) sensors consist of an iron core, an inductive coil and a permanent magnet and an amplifier. A ferrous pole wheel passing the sensor face changes the magnetic field strength, resulting in an AC Voltage being induced in the coil. The signal is converted to a square wave signal with constant amplitude by the integrated amplifier. The frequency of the output signal is proportional to the speed of the moving target.
