The Amphenol DB25P065HTXLF is a standard-density D-sub plug with 25 male pins arranged in two rows — the DB-25 shell size (3, DB, B layout) that mates with the matching 25-position female receptacle. This is the male half you'd find on a cable end or a free-hanging harness, terminated via solder cup for field or bench assembly.
Contact Plating and Mating-Cycle Life
That gold layer is what governs the real reconnect duty — it resists corrosion and contact fretting through repeated mate/unmate cycles, so this plug holds up in field-service applications where a connector gets disconnected and reconnected several times over its life. The copper alloy base material handles the 5 A per contact without excessive temperature rise, but the plating grade, not the current rating, is what decides whether this connector lasts in a corrosive or high-cycle environment.
Termination and Assembly
Solder cup termination — each pin has a cup that accepts a stripped wire end for soldering. This is the classic field-repairable method: you can re-pin it on site with a soldering iron and a basic tool kit, no crimper required.
