The 051529-0123 is a D'M series high-reliability D-Sub connector featuring 9 contacts in size 20 configuration with right-angled PCB mounting. It is designed with copper alloy contacts finished in gold over nickel (Performance Class 2) and a steel shell with yellow chromate over zinc finish, providing excellent corrosion resistance. The connector supports wire gauges from AWG 20-28, operates across a temperature range of -55°C to +150°C, and maintains a maximum contact resistance of 7.5 milli Ohm with a current rating of 7.5 A. With 500 mating cycles and a dielectric withstanding voltage of 1000 VAC at sea level, this connector is well-suited for demanding industrial, telecommunications, and military applications requiring robust interconnection solutions.
