30cm 22AWG JR STRAIGHT Servo Wire Lead Extension Cable Receiver ET0744 RC 300mm

The primary difference between Futaba and JR servo connectors lies in their keying/polarity and housing design. Futaba connectors have a prominent tab on the signal (usually black) wire side of the female connector to ensure correct polarity, while JR connectors typically have beveled corners on the male connector and angled tabs on the female connector to help with alignment. Futaba plugs can often be modified to fit JR connectors, but JR plugs may not fit Futaba receivers without modification.

Futaba and JR connectors are generally compatible due to their similar pin spacing and overall size, though Futaba connectors have a keying mechanism that might require modification to fit into a JR connector housing.

These can be purchase in a wide range of styles Straight, Twisted as an Extension or Y-lead. See table below. The EXTENTIONS cables have a male and female connection. The Y-LEADS have two female to one male and the SERVO extentions have one male and the other end is tinned ready to solder.
