applications where the actuator cannot be direct coupled (only the positive part of the

The actuator is not provided with and does not require any limit switches, but is
electronically protected a

ainst overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement
.
The
G
MX series provides 95° of rotation and a visual indicator indicates position of the
actuator. When reaching the damper or actuator end position, the actuator
automatically stops. The
g
ears can be manually disen

a
g
ed with a button on the
actuator cover.
