The DBM-9W4P-K87 is a D-Subminiature connector from the Combo D series offering mixed contact layouts with a 9W4 arrangement (5 contacts size 20 and 4 empty size 8 cavities). It features a steel shell with pure tin over nickel finish and a thermoplastic insulator (PCT UL 94V-0) for durability and environmental resistance. The connector supports wire gauges from AWG 8–26, carries a maximum signal contact current rating of 7.5 A, and withstands 500 VAC dielectric voltage at sea level. Operating across a wide temperature range of -55 °C to +125 °C and passing 20 hours of salt spray testing, this connector is well-suited for industrial, aerospace, and marine applications requiring reliable mixed-signal interconnection in harsh environments.
