Peak-and-hold solenoids are utilized when an application requires faster actuation times, lower average power consumption, lower heat generation, or smaller package size. Here, higher current is applied to the solenoid at its open or maximum airgap condition. Once the solenoid has completed its travel to the closed or minimum-airgap position, current is reduced to a hold current level, to maintain the solenoid in this position until removed. The current amplitude and time duration of peak-and-hold drive signals are customizable to application requirements.
