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.","metaTitle":"TE 66181-1 Multimate III+ Socket Contact, 16-18 AWG, Gold","metaDescription":"TE 66181-1 stamped socket contact for Multimate III+ series.
