5 - Decide on PC Tail Length & Diameter

The tail length of the PCB is the portion of the contact that extends beyond the rear of the shell. The length will vary in relation to the mounting flange and the series of connector selected.

The PC Tail length is measured from the BACK of the flange to the TOP of the tail (see dimension A)
The outside diameter of the PCB tail is determined by the inside diameter of the plated through-hole on the pc board.
