Spring return rotary actuators MX41-7 have a rotary output for
direct coupling to air dampers. Models are available for on/off
Operation from 230Vac or 24Vac power supplies and 24Vac fl o-
ating point control.
•
Direct coupling to all normal dampers without mounting
brackets or linkage kits - saves site time;

ts up to 19mm diamters up to 13mm square;
•
Case IP 54;
•
Clockwise and counterclockwise rotation available, deter-
mined by Left or Right hand mounting;
•
Spring tensions whilst the damper is being operated;
•
Positive spring return operation, for example under power
failure;
•
Provides 95° of rotation; rotation limiting available;
•
Visual position indicator;
•
Optional built-in auxiliary switches to provide for interfacing
or switching;
•
Cable gland and Blanking plugs supplied fi tted;
•
