0.050" Pitch, 20-Position Shrouded Header
The 5-104076-1 is a 20-position, dual-row header from the AMPMODU System 50 series, on a 0.050" (1.27mm) mating pitch. The 0.100" (2.54mm) row spacing gives a compact but routable footprint for board-to-board or cable interconnects. A 3-wall shroud protects the male pins during handling and guides the mating receptacle into alignment, reducing the risk of bent contacts in production or field assembly.
Gold Mating Finish for Signal-Duty Cycles
The mating interface is gold-plated at 30.0µin (0.76µm) over a copper alloy base, while the solder posts receive a 150.0µin (3.81µm) tin finish. The gold on the mating side supports repeated connect-disconnect cycles without oxidation buildup — a practical advantage for test points or modular assemblies that see field service. Rated at 30 VAC, this header is intended for signal-level circuits, not power distribution. The operating temperature range of -65°C to 105°C covers most automotive and industrial cabinet environments.
Mating and Application Fit
This header mates with AMPMODU System 50 receptacles that accept the same 0.050" pitch and dual-row layout. The push-pull fastening type means no locking latch — the shroud provides the primary alignment, and the friction of the contact beams holds the pair together. Applications listed include automotive, general purpose, medical, and telecommunications. The through-hole termination with 0.100" (2.54mm) post length suits standard PCB thicknesses. The UL94 V-0 thermoplastic housing and black insulation color are typical for equipment inside an enclosure requiring flame rating.
