This 500 mm 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 500mm(19.68").
