The TE Connectivity 213843-3 is a socket contact from the Multimate.125 Powerband series, designed as a crimp-terminated power terminal for 8-10 AWG wire. This is a socket, so it terminates the wire that plugs into a pin header or receptacle cavity.
The 8-10 AWG wire range is the primary fit check for a harness builder — this terminal accepts stranded power cable in that gauge, crimped with the appropriate Multimate die set. Silver-plated copper gives low contact resistance at the crimp joint, important for minimizing voltage drop in a power circuit.
This socket mates with the Multimate.125 Powerband pin contacts and inserts into the standard Multimate housing cavities — the same.125-inch centerline spacing that defines the series.
