The Kpower MM0160 is a metal-gear micro servo for RC models, UAV mechanisms, micro robots and robotic grippers. Its 23 × 12 × 30 mm body weighs 15.5 g and uses a brushed DC motor. Torque is specified as 2 kg·cm at 4.8 V and 3 kg·cm at 6.0 V, with corresponding speeds of 0.14 and 0.12 s/60°, helping match actuation requirements to the supply voltage.
Features
Metal gears driven by a brushed DC motor, with potentiometer position sensing.
Externally splined output shaft with a threaded center opening; horn spline specification: 25T, Ø4.9 mm.
Two mounting tabs with holes for mechanical attachment.
Silver-colored center housing with black end sections.
120° travel angle, with customization stated for the travel range.
PWM, TTL and RS-485 protocols listed.

Applications
RC aircraft and UAV mechanisms: Compact actuation for model-aircraft linkages, including fixed-wing RC aircraft, where the 15.5 g weight helps limit added mechanism mass.
RC cars, boats and ships: Linkage actuation in model mechanisms, including the listed 1/8- and 1/10-scale RC car applications; the splined output provides a horn attachment interface.
Micro robots and robotic grippers: Positioning compact joints and gripper linkages using the metal gear train and potentiometer feedback.
Intelligent medical-device mechanisms, including endoscopes: Small positioning mechanisms where the 23 × 12 × 30 mm form factor is relevant to mechanical integration.
