This 300mm Y-cable is typically used to connect two servos to a single servo port on an RC receiver or servo controller. It has a single female JR connector connected to two male JR connectors, which means it is compatible with almost all of the RC servos.The connectors have gold-flashed contacts on a 0.1" spacing.The split occurs near the midpoint of the cable, so the two male ends can be separated by up to approximately 300mm. * Black: GND * Red：Servo power * White：Signal Applications * RC car, plane and helicopter servo connection or receiver connection Shipping List * Servo Y extension cable(300mm) ( 11.81") x1 https://elecena.pl/product/22714536/servo-y-extension-cable-300mm-discontinued 2023-03-06 https://elecena.pl/product/22714536/servo-y-extension-cable-300mm-discontinued 2024-09-19
