Board-Edge Straddle-Mount Connector for High-Density Routing
The Amphenol MET008431401101 is an 84-position female edge-card connector from the Mini Cool Edge 0.60mm series. It mounts astride the PCB edge — straddle mount — so the board itself forms the mating interface, with contacts on both sides reading the dual-row edge pads. The 0.024" (0.60mm) pitch packs 84 circuits into a compact footprint, suited for high-density backplane or mezzanine card applications where board real estate is tight.
What the 0.60 mm Pitch and Straddle Mount Mean for Your Layout
The straddle mount means the connector sits at the board edge with solder tails on both top and bottom; the PCB must have a cutout or slot to accept the connector body. The specified card thickness of 0.062" (1.57 mm) is standard FR4, so no special board stack-up is required. The dual readout (contacts on both sides of the card) doubles the signal density per edge inch compared to a single-sided edge connector.
84 Positions — Exact BOM Line Match
84 positions, dual rows, 0.60 mm pitch. The position/bay/row breakdown is 28 and 14.
Gold Plating and Contact Design for Reliable Interconnects
The cantilever contact type provides a wiping action during insertion, cleaning the card finger surface. The copper alloy contact material offers good spring properties and conductivity.
How MET008431401101 Compares to the 84-Position Sibling MET008431401311
The MET008431401311 is the closest functional peer — same 84 positions, same 0.60 mm pitch, same gold 30.0µin finish, same straddle mount, same card thickness. The only difference in the spec record is the position/bay/row arrangement: the MET008431401101 lists 28; 14 while the MET008431401311 lists 14; 28. This suggests the bay grouping order is swapped — the physical pinout on the card edge may differ. If your existing card layout expects one bay ordering over the other, confirm the finger pattern against the product drawing before substituting. Both parts are active and RoHS compliant.
