GSM Series Feedback Devices
Standard GSM Series actuators use encoders as their primary feedback
device. Depending on the amplifier that will be used to operate the
actuator, the hookup of the actuator can vary. Always consult Exlar for
the correct wiring details or visit www.exlar.com.
2.4 Cable Routing
Over time, liquid contaminants such as oil and cleaning solutions will
run down the cables and into any exposed connectors. To minimize the
introduction of contaminants to the connector, route the cables so that
there is a loop in the cable just prior to its attachment to the connector.
Two examples are shown below, depending on the orientation of the
connectors. Units mounted in such a way that the connectors are on the
bottom surface of the actuator require no looping.
2.5 GSM Series Linear Actuator Anti-rotation Option
The unique design of the GSM Series linear actuators allows the
extending rod to rotate. This simplifies the setup of the actuator by
allowing the user to rotate the rod and thread it in and out of the actuator
for mechanical attachment or system testing.
This feature also requires that the rod be kept from rotating when used
in its dedicated application to insure proper linear motion. In most
applications, such as those where the load is coupled to linear bearings
or some other support device, the load cannot rotate, providing anti-
rotation for the extending rod of the actuator.
For applications in which the load is free to rotate, Exlar offers the anti-
rotation systems shown below. The drawings on the next page show the
rod and bushing on only one side of the actuator. For long stroke
actuators, the rod and bushing are required on both sides of the actuator.
