with many options.
Options for expanding the basic device can be found in
chapter 5.3.Options.
The rotary actuator is a compact and powerful actuator system which
ensures a long service life. The rotary actuator has been designed
for direct or alternating current at varying output and for torques from
25 to 300 Nm.
The utilized materials guarantee maintenance-free operation and
ensure a low thermal load. All standard version rotary actuators feature
manual emergency actuation and two additional limit switches and
are tested by the manufacturer. The limit switches have been set to
0 ... 90° swivel operation.
The electromotive rotary actuator is available as an On/Off or variable
speed actuator.
