Servo Extension Jumper Cable 12" (F/F)

This 12-inch (300-mm), twisted cable has 22-AWG wires and female “JR”-style connectors on both ends, the same kind of connector commonly found on RC hobby servos. It can be used to make connections between devices with 0.1" 3-pin male headers, such as between RC servo controllers or RC receivers and motor controllers with an RC interface. It can also be a convenient way to connect various 3-pin sensors to a robot controller. The cable’s conductors each consist of 60 strands, making it much more flexible than standard servo cables, and the wires are twisted to reduce electromagnetic interference (EMI).

This servo extension cable has female JR connectors on both ends, so it can be used to make connections between devices with 0.1" 3-pin male headers, such as between RC servo controllers or RC receivers and motor controllers with an RC interface. The cable’s connectors are commonly found on RC servo leads and work with both male JR and male Futaba J connectors. They have gold-flashed contacts on a 0.1" spacing and are joined by 22-AWG, 60-strand wires that make this cable more flexible than standard servo cables.

Note: The cable’s female connectors are the same as what is found on most generic servos and fits nicely with 0.1" male headers, but is often referred to as “male” in the RC hobby industry. The picture below shows the cable connectors labeled with our gender convention.

Servo cable color convention

  • brown or black = ground (GND, battery negative terminal)
  • red = servo power (Vservo, battery positive terminal)
  • orange, yellow, white, or blue = servo control signal line
