Dual-Port Stacked D-Sub Connectors

NorComp Dual-Port Stacked D-Sub Connectors provide multiple connector ports in a limited PCB space by stacking two right angle D-Sub connectors atop each other. These high-temperature, UL 94V-0 thermoplastic connectors are available in four industry-standard sizes (9, 15, 25, 37) and three different connector spacing options (0.625” | 0.750” | 0.900”). Each connector offers high performance, stamped contacts, and a condensed footprint. NorComp Dual-Port D-Sub Connectors include male / female over male / female configurations with hardware options that include flush inserts, hex standoffs, metal brackets, and more.
