The 7 (5 + 2 Coax or Power) position count means you run signal lines through the machined gold-plated contacts and reserve the two coax cavities for RF or higher-current circuits, all in one connector footprint. This avoids a separate RF connector on the panel and keeps the harness count down. The solder cup termination on each machined bronze contact lets you hand-wire individual conductors without a crimp tool — useful for low-volume builds, prototypes, or field repairs where a crimp die set isn't available. Each cup accepts a stripped wire end; you tin and solder it in place. The trade-off is assembly time per position versus a crimp-and-insert terminal. ## Rated for 7.5A Across a Wide Temperature Range Each contact is rated 7.5A at 300V, which covers typical control, sensor, and low-power signal circuits. The 7.5A per-contact rating is limited by the contact size and the thermoplastic dielectric — it is not a power-bus rating, but it is adequate for the mixed-signal role the 7W2 layout serves. The steel shell with tin plating adds EMI shielding continuity when mated with a conductive backshell. ## Panel Mounting and Mating Half This is a panel-mount receptacle with an unthreaded housing flange. It mounts from the rear of the panel; the mating plug's jack-screws (or a separate bracket) provide the clamping force. The shell size is 2 (DA, A) — the standard DA footprint for a 7W2 combo shell. The mating connector is a D-Sub combo plug with the same 7W2 cavity layout, typically from the same TW series or a cross-sourced equivalent. The coax/power cavities accept the appropriate coax or power contacts (not included with this receptacle).","metaTitle":"L77TWA7W2S D-Sub Combo Receptacle, 7W2, Solder Cup, 7.5A","metaDescription":"L77TWA7W2S D-Sub combo receptacle, 7 (5 + 2 Coax or Power) positions, solder cup termination, 7.5A, -55°C to 155°C.
