Non-captive

It has a lead screw going through the motor and has no reasonable stroke limits but must be attached to an assembly that will not rotate. This will then allow the lead screw to extend and retract without rotating. The screw can travel freely in and out of the motor body. In certain setups the motor may serve as the drive and the nut in the assembly. The anti-rotation is by the attachment point and is commonly a cut or machined thread on the end of the screw. The non-captive is potentially the shortest overall length assembly.
