It accepts 16-18 AWG wire and terminates via solder, making it a field-serviceable option for harness builders who need to attach a contact to a wire before inserting it into a housing.
Wire Sizing and Termination
This socket accepts 16-18 AWG stranded wire — the sweet spot for moderate-current signal or power circuits in a Multimate III+ housing. The solder termination means you tin the stripped wire end and flow solder into the contact barrel; no crimp tool required. For a harness builder, that simplifies field repair but adds a soldering step compared to a crimp terminal.
Plating Grade and Duty
It is specified for applications where the contact will be mated and unmated dozens of times over the product life, or where the operating environment includes humidity, mild chemicals, or temperature cycling. The gold layer resists oxidation that would increase contact resistance on a tin-plated part. For a single-install, never-touch-again wire, tin would suffice; the 30.0 µin gold here says the designer expected reconnect duty.
