Overview

The FS5103B is a general-purpose standard-size analog servo from FEETECH. The output shaft is supported by two ball bearings for reduced friction. The FS5103B works with standard RC servo pulses, providing a running angle of approximately 180° over a servo pulse range of 600 µs to 2400 µs, and it has a 12″ (30 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible. You can find more information about this servo in its datasheet (435k pdf).

The servo cable is terminated with a Futaba-compatible JR-style connector.

This servo is also compatible with our Mounting Bracket for Standard-Size Servos:

For more advanced robotics applications, please note that we also carry a version of this servo that is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, which lets you monitor the actual position of the servo from your controller:

Note that, as with most hobby servos, stalling or back-driving this servo can damage it.

Comparison to the Power HD 3001HB servo

This servo is a lower-cost alternative to the 3001HB from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5103B and the 3001HB side by side:
