Remote Actuator Technology
The remote actuator cable assembly consists of a wire cable inside
of a plastic insulated spiral wire casing.
Identifying a proper routing of the cable assembly is important. De-
viations from line to line placement will require bends in the cable
with resulting losses in the overall assembly. These inefficiencies
show up as friction losses and lost motion.
Frictional losses are increases in actuation force due to losses in the
assembly. Lost motion is an undesirable difference between the in-
put end of the assembly and the output end.
The principle element of lost motion is backlash and deflection.
Backlash is caused by the wire cable moving inside the casing with
the change in direction of motion. It is the function of clearance bet-
ween the wire cable and casing, plus the number of degrees of
bend in the cable assembly. Deflection of the cable assembly, while
usually low, can be minimized by anchoring the casing.
This is especially true in those applications of cable assemblies with
long lengths and/or large degrees of bend in the system.
All of these losses and resulting inefficiencies can be reduced by the
equipment designer through minimizing the total degress of bend in
the assembly. Because of the number of variables effecting proper
operation of any remotely actuated switch assembly, it is important
that the ordering instructions be used to determine proper cable
length and to provide samples for customer approval.

assembly application.
