New Product: RSF-3 Ultra-miniature Actuator

A new ultra-miniature servo actuator is now available from Harmonic Drive! Measuring just 12mm square x 47 mm in length, the RSF-3 brushless actuator delivers maximum torque up to 1.8 in-lb and maximum speeds up to 333 rpm, depending on gear ratio.

Zero-backlash harmonic drive gearing provides positional accuracy better than 10 arc minutes and a 200 line, 2 channel incremental encoder (w/ index) gives a minimum resolution of 24,000 ppr at the output shaft. Ideally suited for precision servo applications where available space is at a premium.
