9g 270° Metal Servo with Analog Feedback (1.5kg)

The 9g 270° Metal Servo with Analog Feedback is a compact, durable micro servo designed for precise motion and position sensing in robotics projects. Featuring metal internal gears and a 0 to 3.3V analog feedback signal, it is well suited for makers, students, and engineers building closed-loop robotic mechanisms.

Extended travel and metal gears

Equipped with rugged internal metal gears, this servo offers significantly greater durability than standard plastic alternatives. It provides an expanded operating range of approximately 270 degrees using a 500 to 2500 microsecond pulse range, with no internal mechanical stop to allow smooth 360-degree manual rotation.

Closed-loop analog feedback

The built-in potentiometer outputs a 0 to 3.3V analog position signal directly to your microcontroller. This allows your system to monitor actual horn position in real time for accurate closed-loop control and interactive positioning tasks.

Compact footprint and high torque

Weighing just 12g and measuring 22.9 x 12.2 x 32.5mm, this micro servo delivers a stall torque of up to 1.5kg.cm at 6.0V. Its low power consumption allows it to operate reliably from standard 4.8V to 6V battery or USB power sources.

Four-wire connection interface

The servo features a four-wire lead consisting of red for positive power, black for ground, white for the PWM control signal, and brown for the analog feedback output.

Mounting accessories included

Each unit comes with four different servo horn styles to accommodate a broad variety of linkages, steering arms, and mechanical assemblies.
