ML6275
Spring Return
Direct Coupled Rotary Actuator
FEATURES
Mounts directly on horizontal 3/8 in., 1/2 in., and
5/8 in. round and square damper shafts by using
the appropriate insert. Most models are shipped with
1/2 in. insert.
•Provides 25 lb-in. running and spring return torque.
•Magnetic coupling eliminates the need for mechanical
stops or limit switch adjustments by limiting stall
torque to 60 lb-in. maximum.
•95° stroke provides necessary compression of rubber/
neoprene gaskets commonly used on 90° low leakage
dampers.
88 second synchronous timing can eliminate need for
feedback position indication in closed-loop
temperature control applications.
Removable splined output hub permits premounting of
hub on damper shaft, providing installation flexibility.
•Reversible mounting allows actuator to be used for
either clockwise (cw) or counterclockwise (ccw)
spring rotation.
Designed for both single-point and three-point
mounting, to allow installation flexibility.
•Available with or without a time-out feature. Models
without the time-out feature are designed to be used
with intelligent building management system and/or
controller.
Standard models have two 8 mm by 12 mm long set
screws for securing the damper shaft. Actuator models
available for various shaft sizes that allow damper shaft
to operate centered inside the output hub.
Standard one-meter cable with color-coded leadwires
allows external wire connections with 1/2 in. conduit
connectors.
•Two or more actuators can be mounted on one
damper shaft to increase output torque for use on
dampers larger than eight square feet.

APPLICATION
The ML6275 Spring Return Direct Coupled Rotary Actuator is
a floating control motor with an internal, electrically isolated
feedback potentiometer that can be used with controls that
provide switched or floating single pole double throw (spdt)
control output to operate dampers in heating, ventilation, and
air conditioning (HVAC) applications. The feedback potentio-
meter provides indication of the motor output hub position and
can be used for rebalancing an internal control circuit.
