The 0022112092: The 20.0 µinch gold-over-nickel on the mating face lifts the cycle life well above what a tin interface can deliver; in a medical or field-service harness where the connector sees quarterly reconnects, that gold layer keeps the contact resistance stable for decades. It is not a secondary TPA, but for a single-row header it is enough to keep the pair engaged under normal handling.
Where This Header Fits in the KK254 Family
This 9-position vertical header sits in the KK254 series alongside 2- through 12-position siblings. The 0.322" (8.18 mm) insulation height gives a taller shroud than the low-profile KK254 headers, which matters when the mating receptacle needs clearance for a wire dress cover.
Termination and Mating Details
Through-hole solder termination. Mates with KK254 crimp receptacle housings (series 6471 or 2695) that carry the matching 0.100" pitch and friction lock ramp.
