ML4105, ML4115, ML8105, ML8115 FAST-ACTING, TWO-POSITION ACTUATORS
SPECIFICATIONS
Models: See Table 1.
Dimensions: See Fig. 1.
Minimum Damper Shaft Length: 1-3/4 in. (45 mm).
Device Weight: 5 lb (2.3 kg).
Stroke: 95° ± 3°, mechanically limited.
Electrical Ratings: See Table 1.
Electrical Connections:
ML4105A,B, ML4115A,B, ML8105, ML8115: Two color coded
16 in. leads; includes ground screw.
ML4105C1008, ML4105D1007: Terminal block and ground

cable.
Three 7/8 in. holes for conduit connections (fittings not
included).
Mounting: 3/8 to 1/2 in. square or round damper shafts.
Actuator can be mounted with shaft in any position. Secure
hub to shaft with:
ML4105A,B, ML8105: Four 1/4-28 UNF set screws. Use
1/8 in. Allen wrench to tighten set screws.
ML4105C,D: Four 3 mm set screws. Use 3 mm Allen
wrench to tighten set screws.
ML4115, ML8115: Two 1/4-28 UNF set screws. Use 1/8 in.
Allen wrench to tighten set screws.
IMPORTANT
Honeywell does not recommend using linkages with
these actuators because side-loading of the output
hub reduces actuator life.
Temperature Ratings:
Ambient: 0°F to 130°F (-18°C to 55°C).
Shipping and Storage: -40°F to 140°F (-40°C to 60°C).
IMPORTANT
The actuator is designed to meet UL555S standards
at 350°F (176°C). The actuator must be tested with
the damper to achieve this rating.
Humidity Ratings: 5% to 95% RH noncondensing.
