JR

JR's smaller sized Digital Ultra Torque DS9411 Mid servo offers outstanding holding torque and quicker response. This is achieved by using a high-frequency digital amplifier with a pulse rate of 300Hz (the number of time the amplifier pulses the motor per second) versus the 50Hz found on a conventional servo. The extreme accuracy of digital precision gives a resolution of 5900 steps per 120° of travel and less than .001ms of dead-band. A durable composite-metal geartrain composed of hard-anodized aluminum and hardened steel and brass gears provides backlash- free operation.
