Product information
New digital servos of the highest possible quality The introduction of GRAUPNER/JR digital servo technology has met with enthusiastic acceptance world-wide. JR, with its comprehensive expertise in the field of radio control, has been collaborating with the development laboratory of the Mitsubishi company, and the result is further improved digital micro-processors, and an expanded range of digital servos. This digital micro power servo is controlled by a newly designed micro-computer with its own intelligence, which monitors control signals and calculates any compensation required, e.g. for false signals, thermal drift and other factors which could affect system accuracy. Long-life electric motor with carbon brushes for long useful life. 13-bit ACD system with 5900 steps over full servo travel provide extremely accurate neutral position, maximum possible resolution and smooth positioning characteristics. Minimum possible temperature drift. Special components for high resistance to vibration and mechanical shock. High frequency initial signal to the electric motor- up to about 300 Hz - avoids motor damage and copes safely with long-moment loads.

Operating voltage 4,8 ... 6 V; No-load current drain approx. 14 mA; Max. current drain approx. 285 mA; Torque approx. 13 Ncm (1,3 kg/cm);
Holding power approx. >50 Ncm; Rotary travel approx. 2 x 45°; Transit speed approx. 0,16 s/40°; Dimensions approx. 22 x 11 x 21 mm; Weight approx. 9 g;
