It terminates via solder to a through-hole PCB and carries a panel-mount flange with unthreaded holes — the flange bolts to a chassis or bulkhead while the solder tails anchor to the board, a construction that handles strain at the cable exit without pulling on the solder joints.
The unthreaded flange holes accept a bolt or screw; the flange itself aligns the receptacle to the panel cutout before the solder joints are made. No press-fit, no IDC — plain solder termination, so the assembly step is straightforward reflow or hand-solder.
