The 680M9W4203L401 is a female, 9-position combination D-sub connector designed to transmit both power and signal through a single, robust interface. It features four 40A-rated power contacts that accept up to 8 AWG wire and five 5A-rated signal contacts that accept up to 20 AWG wire, all with solder cup terminations. Constructed with a nickel-plated steel shell, a UL94V-0 rated PBT insulator, and copper alloy contacts with a gold flash finish, this connector operates reliably across a wide temperature range of -55°C to +125°C. This space-saving design is ideal for industrial machinery, telecommunications equipment, and instrumentation where both high-current power and data lines are required in a compact footprint.
