Solenoid loads generally exhibitlarge hysteresis. Application ofthe rated voltage actuates these loads.Once they are in position, however, youcan use a significantly lower voltage tothereafter ...

Solenoids are used in many applications to provide linear or rotational actuation in mechanical systems. Although driving solenoids can be as simple as switching the current flow on and off, ...

Several years ago, Paul Rako, in collaboration with the late, great Bob Pease, wrote a terrific article about the finer theoretical and practical points of electromagnetic solenoid-driver circuits. 1 ...

Several safety-critical solenoids in a laser-measurement system on an automotive-assembly line required protection from internal overheating during normal operation. After a 60-sec activation, the ...

When I think of economizer circuits for solenoids and relays, I’m reminded of the phrase, “you can’t have your cake and eat it, too.” This phrase comes to mind because if you use a solenoid economizer ...
