The 5-103634-9 is a latching header without hold feature designed for the AMPMODU Mod IV single-row interconnection system. It features a 0.100 inch [2.54 mm] centerline spacing with dual cantilever beam receptacle contacts and built-in anti-overstress protection for reliable connections. The header employs closed entry receptacle housings with lead-in ramps for positive mating, built-in guides for alignment, and polarized design to prevent incorrect insertion. The housing is constructed from glass-filled thermoplastic rated 94V-0 with duplex plating (0.000010 inch gold on contact area and 0.000150-0.000300 inch matte tin on solder area). This connector is ideal for printed circuit board applications requiring secure, polarized connections in compact, stackable configurations, particularly in VLSI and instrumentation applications where reliable signal integrity is essential.
