The TE Connectivity 1-2372484-3 is a 98-position, dual-row female card edge connector built for PCI Express Gen4 applications. The 98 positions split across two rows (11 in one bay, 38 in the other) match the standard PCIe x16 lane count, so this is the receptacle end of the link. The black PA9T glass-filled housing carries a locking ramp to hold the mating card in place once seated.
The 1.00 mm pitch is tight enough to route differential pairs under the connector body on a standard server motherboard, but it forces a board-edge pad pattern that matches the straddle-mount footprint — the PCB must have a slot or edge fingers that align with the contact cantilevers. The straddle mount opening is unthreaded at 0.087" (2.20 mm) wide, so the board slides into the connector body and the solder tails reflow onto surface pads on both sides of the board. There is no through-hole soldering; the termination rows mirror the contact rows, meaning the PCB needs pads on top and bottom at the edge.
Gold Plating and Contact Design for Repeated Mating Cycles
The locking ramp adds mechanical retention so the card does not walk out under vibration in a rack-mount server or GPU chassis.
