The 1.25A per-contact rating places it firmly in the signal domain, not power delivery. The feed-through feature allows daisy-chaining multiple connectors on the same ribbon cable, a practical advantage for bus-style wiring.
Why the 1.25A Rating and IDC Termination Matter
At 1.25A per contact, this connector is not for power rails or motor drives — it is a signal-only D-sub. The IDC termination accepts 26-28 AWG stranded or solid wire, meaning you terminate the entire cable in one press operation rather than crimping each pin individually. That saves assembly time on multi-conductor ribbon cables but locks you into that wire gauge range; you cannot use heavier wire for higher current. The gold contact finish on phosphor bronze gives a reliable connection over many mate/unmate cycles, which matters if this plug lives in a field-serviceable panel or a test fixture.
Mating and Mounting: What It Connects To
The flange features 4-40 threaded inserts for jackscrew locking, which is the standard D-sub retention method. It is a free-hanging connector, so no PCB footprint is involved; the cable exits the back and the connector floats in the harness. For panel-mount applications, you pair it with a mating receptacle that has a panel-mount flange.
