The 5-104186-9 is a single-row, vertical unshrouded thru-hole header connector designed for board-to-board interconnection in the AMPMODU System 50 connector family. It features 15 positions with a 0.050 inch (1.27 mm) typical centerline spacing and a 0.100 inch (2.54 mm) post spacing, providing a compact footprint of 0.765 inches (19.43 mm) in length. The housing is constructed from glass-filled thermoplastic rated 94V-0, with copper alloy contacts duplex plated with 0.000030 inch (0.00076 mm) gold in the mating area, 0.000150 inch (0.00381 mm) tin on solder posts, and an entire contact underplated with 0.000050 inch (0.00127 mm) nickel for enhanced durability and solderability. This connector is ideal for applications requiring reliable board-level interconnections in compact spaces, such as telecommunications equipment, industrial control systems, and consumer electronics where consistent electrical performance and mechanical stability are essential.
