It terminates individual 26-28 AWG wires directly into the housing using an insulation displacement contact — no crimp terminals, no applicator tooling, just a simple press.
Tin is more economical than gold, but it oxidizes over time and the oxide layer can increase contact resistance if the connector is repeatedly disconnected and reconnected. For a fixed harness assembly inside an enclosure, tin is perfectly adequate.
The 2-173985-3 is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — both are confirmed at quote time. No stock-holding or firm price is published here.
The cable pitch and board-side pitch are both 0.079" (2.00 mm), matching the standard CT Amp-In header footprint.
