What the 193797-1 contact is
The TE Connectivity 193797-1 is a socket (female) crimp contact from the Universal MATE-N-LOK II series — the power side of that connector family. It accepts 10 AWG wire and terminates with a standard crimp tool, so you can re-pin a damaged housing or build a custom harness on site without waiting on a pre-molded assembly.
Silver plating — why it matters for a power contact
The contact finish is silver at 200.0µin (5.08µm) — that's a heavy plating, not a flash. Silver handles higher current density than tin without welding at the mating interface, and it holds up under the sustained temperature rise a 10 AWG power circuit generates. For a socket that's going into a motor drive, a power supply, or a battery interconnect, this is the right plating grade.
This socket crimps into the Universal MATE-N-LOK II housing cavities — the same series that uses a positive-lock latch and a secondary locking wedge to keep terminals from backing out under vibration. It's the female half that receives the male pin contact in the header or plug housing. If you're rebuilding a harness that uses the Universal MATE-N-LOK II system, this contact crosses into the housings you've already got.
