Board-to-Board Sizing: 24 Circuits at 0.100" Pitch
The 66953-012LF: The 30 µinch gold on the mating face, over brass contacts, supports repeated connect-disconnect cycles without fretting corrosion — a good fit for test equipment, medical devices, or any board that sees field service. Rated 1250V, the insulation system (glass-filled polyester, UL94 V-0) gives substantial headroom for 48V telecom, 400V industrial bus, or medical isolation barriers — the voltage rating is not the limit of the contact itself but of the creepage path through the housing.
Mating Half and Build-to-Print BOM
This receptacle mates with a 0.100" pitch dual-row pin header — typically the Dubox™ or BergCon® PV™ series male headers. The contact finish on the post is tin (100 µinch), compatible with leaded or lead-free wave solder. The connector ships in a tube. Contacts are integral to the receptacle — no separate terminal to order.
