The miniature GVCM-019-032-02 linear voice coil servo motor is ¾-in. in diameter and features a 0.875-in. stroke. This miniature linear servo motor features a continuous high-force-to-size ratio of 7.4 ounces and 23.3 ounces of peak force at a 10% duty cycle. The housing is only 1.25 in. long and combined with coil end the total length is 1.438 in. In the fully extended position, the threaded shaft extends 1.156 inches beyond the face of the housing and the end of the shaft has a 2-56 UNC-2A thread 0.156 inches long for backlash free connections. Both the housing and coil ends of the actuator have two 4-40 UNC-2B threaded mounting holes on 0.313-in. bolt circles. They should be considered as low-cost replacements for pneumatic linear actuators.
