Honeywell Direct Coupled Actuator, 175 lb-in - MS4120A1001/U

The Honeywell Direct Coupled Actuator, offering 175 lb-in torque, epitomizes the perfect combination of function and design robustness. Equipped with a spring return feature, it operates effectively between 100-250 VAC while maintaining a rating of 60 VA. This two-position, SPST actuator is designed with a self-centering shaft adapter, innovatively crafted to accommodate a wide range of shaft sizes. It also offers models enabled with Honeywell's proprietary Sylk communication protocol.

Technological ingenuity is evident in the purposefully crafted access cover that significantly simplifies connectivity tasks, along with the metal housing that encompasses built-in mechanical end limits for extra durability. The spring return direction can be selected in the field based on requirements, ensuring versatile application in various environments. A built-in shaft position indicator and scale enhance usage clarity, and the manual winding capability further comes with a locking function for increased safety.

The reliability of this Honeywell Actuator is doubly ensured as it is UL (cUL) listed and all models are plenum-rated according to UL2043. Additional convenience is offered with certain models that come with a 3 ft 18 AWG color-coded cable.

With power consumption ranging between 100-250 VAC, it is adaptable to different power supply levels. Designed for rigorous performance, it can efficiently operate in a wide range of temperatures from -40 F to 150 F (-40 C to 65 C). Field wiring of 14-22 AWG to screw terminals is facilitated under the conveniently removable access cover, allowing for easy electrical connections. The actuator also contains two SPDT auxiliary switches. The housing is integrated with a self-centering shaft adapter (shaft coupling), which further underscores its overall practical design.
