35 A Power Receptacle for Inline Harness Routing
The TE Connectivity 2204534-1 is a 3-circuit Elcon Mini receptacle housing silver-plated female sockets rated 35 A per circuit at 400 V. The 0.224" (5.70 mm) pitch provides enough creepage distance for the 400 V rating without inflating the connector footprint — important when routing a power harness through a tight enclosure.
Silver Plating: Power Duty Over Cycle Life
Silver contacts with 3.00 µm (0.076 µm) finish are standard for high-current power interconnects — silver's bulk conductivity beats tin for carrying 35 A without excessive temperature rise. The trade-off is that this thin silver layer won't survive hundreds of mate-unmate cycles like a gold-over-nickel contact would. For a battery-to-busbar connection that mates once and stays, it's the right call. For a field-service connector that gets swapped quarterly, you'd want a thicker precious-metal plating.
Mating Half and Wiring
This receptacle mates with the Elcon Mini 3-position male header at 5.70 mm pitch. The crimp terminals accept the wire gauge specified in the Elcon Mini application tooling guide — typically 14-16 AWG for the 35 A rating, though confirm with the terminal datasheet for your exact wire size. The pull tab feature aids connector separation in tight harness bundles where finger access is limited.
