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.
