Utilized where precise positioning of a mechanism over a range of movement is required. Two critical design requirements that must be met for a proportional control solenoid are low hysteresis and a relatively flat force vs. stroke curve at a given applied current.
If the voltage steps are applied at a repeated frequency and the percentage "on time" (high voltage) is varied, the current applied to the solenoid will vary and the force created by the solenoid will vary from minimum to maximum. This type of voltage control, where the percent on time is varied, is called "pulse width modulation" control.
