M.2 NGFF Card Edge — 67-Position, 0.50 mm Pitch
The Amphenol FCI 10131758-004RLF is a 67-position female M.2 (NGFF) Mini Card edge connector from the HPCE® series. It mates with the standard M.2 module edge fingers, accepting cards of 0.031" (0.79mm) thickness. The 0.020" (0.50mm) pitch and dual-row readout place this in the B-keyed or M-keyed footprint range — the 67-position count is specific to certain M.2 module lengths and keying notches, so confirm the module's edge connector matches before layout. Right-angle SMT termination keeps the module parallel to the motherboard, saving z-height in thin embedded systems like SSDs, Wi-Fi cards, or cellular modems.
Gold Plating — 15.0 µin Mid-Grade for Standard Mating Cycles
The 10131758-001RLF carries a 1.00 µ" flash — fine for one-time install or very low cycle counts. The 10131758-005RLF uses 30.0 µ" gold for high-durability applications (frequent module swaps or corrosive environments). The 15.0 µ" gold here suits standard M.2 duty: a few insertion cycles over the product's life, typical of an SSD or wireless card that stays mated once installed.
