What this connector is
The Amphenol 93690-105-32LF is the 32-position member of the BERGSTIK unshrouded dual-row header series — a breakaway-style header that ships fully loaded and accepts both press-fit and solder termination into a 0.100 inch (2.54 mm) grid. Contacts are square male pins; the mating face carries Gold GXT plating at 30.0 µin (0.76 µm) while the post side is tin-finished at 39.4 µin (1.00 µm). Rated 5 A per circuit at the board level, with a 110 V dielectric withstanding rating. The insulator is black thermoplastic rated UL94 V-0, making it suited for internal equipment builds where flame-retardance is a compliance gate.
What the plating grade decision means
The split finish — gold GXT on the mating interface, tin on the post — is the selection call on this series. Gold GXT at 30.0 µin gives reliable wipe engagement and resistance to fretting at first mate; the tin post is sized for a durable solder joint or press-fit barrel. If your board sees repeated field reconnects, the gold mating finish is what sustains contact resistance across cycles. If this is a permanent in-panel install with no further mating, the tin post still covers the joint reliably. The UL94 V-0 rating on the housing material gates it into equipment enclosures where the flame class is a procurement requirement.
