5499141-9 is a pin header connector designed for ribbon cable interconnect applications with integrated receptacles and strain relief. This connector features a 40-position configuration with a 0.100" x 0.100" [2.54 x 2.54 mm] center spacing and a 0.110" [2.79 mm] soldertail length, enabling direct soldering to PCB layouts. The connector is compatible with 0.050" [1.27 mm] centerline ribbon cable and provides reliable mass termination capabilities, allowing simultaneous connection of multiple conductors without individual wire preparation. The integrated strain relief and receptacle design enhance mechanical durability and signal integrity in board-to-board and cable-to-board interconnect applications commonly found in computer peripherals, industrial equipment, and telecommunications systems.
