Torque: 2.1 [kgf・cm]
Speed: 0.19 [s/60°]
Weight: 12 [g]
Dimensions: 27.9 x 16.0 x 23.9 mm
Power supply voltage: 5.0 [V] (3.7 to 6.0 [V])
Range of motion: 300 [deg]
Communication format: TTL half-duplex communication/PWM method

Compact and lightweight servo with resin gears

This is the smallest servo in the series, 40% smaller in volume than the RS304MD and capable of daisy-chain connection with an ADH connector. Communication is compatible with the command method/PWM method common to the RS series. It is easy to use as a small communication robot or a small actuator in the IoT field.

Option

We have prepared connecting parts that can be easily attached to the frame and can create a perpendicular two-axis joint.
By attaching a free horn, a biaxial support structure is also possible.
