M.2 NGFF Connector, 67-Position, 0.50 mm Pitch
The TE Connectivity 2199119-4 is a 67-position female M.2 (NGFF Mini Card) connector built for the standard 0.50 mm pitch edge-contact interface.
67-Position Footprint and M.2 Key Compatibility
The 67-position count is the full-size M.2 card edge pinout — the connector accepts M.2 modules with the standard 75-position edge (the 67 populated positions leave the remaining 8 positions for keying notches). The connector itself is unkeyed (no plastic keying tab in the housing), so it mates with both Key B and Key M modules as long as the module's edge connector matches the 67-position layout.
Gold Plating Grade: 15.0 µ" vs Flash
Compare this to the 2199119-1, which uses flash gold plating — that variant is suited for single-mate applications where the connector mates once during manufacturing and stays. The 15.0 µ" gold on the -4 gives you a measurable wear layer for multiple insertion cycles, which matters if the module will be swapped during field service or testing. The rest of the spec — 67 positions, 0.50 mm pitch, right-angle SMT, black housing, board guide — is identical between the two.
