Overview

The Kpower M09YY is a 12 g metal-gear micro servo for RC aircraft, UAV mechanisms and micro robots. Its compact 23 × 12 × 24.3 mm body, mounting tabs and 270 mm three-wire lead support installation in small mechanisms. Operating from 4.8–8.4 V, it provides voltage-dependent torque and speed, with a DC brushed motor, potentiometer position sensing and a 900–2100 μs control-pulse range.

Features

Metal gearing and a splined output shaft for transmitting motion to a servo horn.
Opposing mounting tabs with mounting holes for securing the servo.
DC brushed motor with potentiometer position sensing and an 8 μs dead band.
Plastic case, two ball bearings and a 270 mm three-wire lead.
120° travel angle, with customization stated for the travel range.

Applications

RC aircraft and other RC models: actuate small control linkages using the compact 12 g servo and its mounting tabs.
UAV mechanisms: position small onboard mechanisms where the compact body and 270 mm lead help with installation and cable routing.
Micro robots: drive small joints or linkages using metal gearing and potentiometer-based position sensing.
Intelligent medical-device mechanisms: provide compact mechanical positioning within the stated electrical and operating limits.
