  • Detection of Plunger Movement in DC Solenoids Through Current Sense Technique
    Publication number: 20180292445
    Abstract: An apparatus and method of detecting movement of a plunger of the solenoid includes detecting a peak (IPEAK) in a current signal applied to a coil of the solenoid. A predetermined threshold is added to the current signal applied to the coil of the solenoid to generate a level shifted signal. The level shifted signal and the peak signal are compared to detect movement of a plunger of the solenoid.
    Type: Application
