Shut-down actuators of model range type GA are produced in sizes of 65 mm to 115 mm diameter, and with stroke lengths between 20 mm and 50 mm.
So, these solenoids are featuring longer stroke movements as compared with solenoids of
type GH.
The movement from stroke starting- to stroke limit-position is performed by the electromagnetic force; for resetting an external power source (spring or weight) is needed.
