RSF-Supermini

These extremely small servo actuators utilize zero backlash Harmonic Drive® precision gears, a brushless servo motor and an incremental encoder to deliver precision motion control. The RSF Supermini series is designed to operate with a wide range of third party drivers as well as Harmonic Drive LLC’s DCJ Series, DDP Series, DEP Series, and HA680 drivers. The units are small enough to fit inside the finger of a robotic hand.

Key Features:

Compact, lightweight
High output torque
High positional accuracy
RSF-5B is available with an optional brake
