This 9-pin connector plug features a 1-inch round insulating body designed for multi-conductor chassis interconnects and radio cable assemblies. The pin configuration consists of eight 3/32-inch outer pins spaced 1/4 inch apart in a circular arrangement, with a larger 5/32-inch center pin (#9) positioned inside the ring.

This polarized pin arrangement ensures proper keying during insertion, maintaining correct circuit connections across all nine conductors.
