DE-9 Plug from the AMPLIMITE HD-20 Series
The through-hole solder termination suits board-level assembly, and the steel shell with tin plating provides basic EMI shielding.
9 Positions, 6A, Gold Contacts — What Drives the Fit
Gold contact finish supports a higher mating cycle life than tin — relevant if this connector lives in a field-service panel or test fixture that sees regular disconnect and reconnect. The unthreaded housing/shell flange means the mating pair relies on a separate locking mechanism (e.g., a slide latch or screw-lock kit) rather than integral jackscrews.
