Actuator Class
KX = high capacity roller screw
KM = standard capacity roller screw – Legacy Product
AA = Frame Size
BBBB = Stroke Length
CC = Screw Lead (linear travel screw revolution)
D = Mounting
E = Rod End Thread / Rod Material
FFF = Input Drive Provisions
GGG = Motor Mount Provisions
Mechanical Options
L1, L2, L3 = Adjustable External Travel Switch(es)
