9g 180° Metal Servo with Analog Feedback (1.5kg)

The 9g 180° Metal Servo with Analog Feedback is a compact micro actuator featuring durable internal metal gearing and real-time position reporting. Delivering up to 1.5kg·cm of torque within a miniature footprint, it is an ideal choice for makers, students, and engineers developing micro-robotics and closed-loop control systems.

Analog feedback for closed-loop control

An integrated feedback line outputs a 0V to 3.3V analog signal corresponding to the horn position. Connecting this output directly to a microcontroller allows your system to monitor actual rotational angles and execute closed-loop positioning.

Durable metal gear transmission

Internal metal gears provide significantly higher durability and wear resistance than standard plastic mechanisms. The unit produces a stall torque of 1.3kg·cm at 4.8V and reaches 1.5kg·cm when powered at 6.0V.

Wide range and compact frame

Measuring 22.9 x 12.2 x 32.5mm with a weight of 12g, the servo fits easily into tight mechanical assemblies. It provides 180 degrees of controlled movement via standard 500 to 2500 microsecond pulses and features no internal mechanical stop, permitting manual 360-degree rotation.

Four-wire connection interface

The servo features a dedicated four-wire harness consisting of red for positive supply, black for negative, white for PWM signal input, and brown for analog feedback. It is designed to operate on a 4.8V to 6.0V power supply.

Included servo horn accessories

Each unit is supplied with four interchangeable servo horn types. These varied horn shapes accommodate different mechanical linkages and mounting configurations out of the box.
