50-position dual-row footprint for signal routing
The 7-534206-5: The through-hole solder tails extend 0.115" (2.92 mm) below the insulator, which is a common length for a 1.6 mm PCB with standard wave-solder clearance.
Gold mating surface for repeated connect cycles
The female socket contacts are gold-plated on the mating end (30.0 µin) and tin-plated on the solder posts (150.0 µin). The gold-to-gold interface keeps contact resistance stable over repeated mate-unmate cycles, while the tin post wets well in a wave or hand-solder process.
