Dubox 5-Pin Receptacle at 2.54mm Pitch
The 65780-005LF: Gold plating on both the mating face (40.0µin) and the post (10.0µin) gives this connector a solid mating cycle life — the 40µin gold on the contact interface is rated for repeated connect-disconnect in field-service or test-fixture applications without fretting corrosion.
The 65780 base product number covers the single-row Dubox receptacle family; the -005LF suffix specifies the 5-position, gold-plated variant.
The contact post is gold-plated (10.0µin), which is standard for solder termination and provides a corrosion-resistant joint.
