FHA-Mini Rotary Actuator

The FHA-C Mini Series is a family of extremely compact Actuators that deliver high torque with exceptional accuracy and repeatability. The actuator combines a high precision Harmonic Drive® gear component with a pancake brushless servo motor. An incremental or multi-turn absolute encoder is integrated to provide high resolution velocity and position feedback. The large cross roller output bearing allows heavy loads to be mounted directly to the actuator without the need for additional support. New options now available: Dual Absolute Encoder and panel mount connectors!

FHA mini actuators are designed to work with a number of servo drives, including REL, RTL, DDP and HA-680 from Harmonic Drive, and MELSERVO-J4 (SSCNET III/H) from Mitsubishi. FHA mini is also available with a servo drive directly integrated into the actuator.
