The DDMM-36W4S is a D-Subminiature connector from the Combo D Series, featuring a mixed contact arrangement with 32 size-20 contacts and 4 empty size-8 cavities for flexible signal and power distribution. This connector supports wire gauges from AWG 8-26 and is rated for 500 mating cycles, with a maximum signal contact current rating of 7.5 A and contact resistance of 10 mO. The connector operates reliably across a temperature range of -55°C to +150°C and withstands 500 VAC dielectric voltage at sea level, with a steel shell finished in yellow chromate over zinc and thermoplastic insulator (PCT UL 94V-0). It features gold-over-nickel plated copper alloy contacts (Performance Class 1) with solder pot termination and .120" (3.05 mm) through-hole mounting, making it suitable for industrial instrumentation, telecommunications, and aerospace applications requiring robust mixed-signal connectivity.
