Control solenoid force - Raspberry Pi Forums


i have 24v push-pull solenoid , need digitally control push force. in understanding, achieved controlling current applied it. first thought using digital potentiometer, seems it's not easy find 1 can support 24v.

there smarter way control solenoid force, or can point digital potentiometer fit task?

thank you

pulse width - shorter pulse, smaller amount of energy "delivered" solenoid.

i'd expect width:force ratio nonlinear , unrepeatable. if need more levels of force, calibration needed each solenoid (even if use same model). material of core important...

don't use potentiometer if find one.
