Wow that sure looks like it! So magnetic actuators are actually variable in distance of motion unlike solenoids that are either energized or not? If so is the amount of motion regulated by a variable pulse of voltage input or a increase in voltage input?
I'm getting tempted to build one of these in copper form. Might have to be a winter project though!
Switching:
Two switching modes can be used for various applications.
Single Holding:
Energized constantly except momentary interruption to release holding so rod
can be reversed.
Energized only during period when holding is required.
Energized only when rod is moving towards the holding end of the stator and
during the holding period.
Double Holding:
Energized constantly except momentary interruption to release holding so rod
can be reversed.
Energized only during period when holding is required.
Double holding coils may be switched together or one at a time.
Note: Double holding coil units are normally supplied with 2 yellow leads and one
small diameter black lead so that the holding coils may be operated
independently by applying rated voltage to the yellow and black lead. The wire
marker on one yellow lead indicates the lead that operates the holding coil on
the lead egress end of the stator. If desired, the 2 yellow leads can be tied
together for simultaneous operation of both holding coils.
