What This PCI Express Slot Connector Is
The TE Connectivity 6-1734774-9 is a 64-position female edge connector designed specifically for PCI Express™ add-in cards. It uses the standard 0.039" (1.00mm) pitch that matches every PCIe slot footprint, and its 64 positions correspond to the x1 lane configuration — the most common PCIe slot count on motherboards and riser cards. The dual-row readout means it contacts both sides of the PCIe card edge, giving you the full complement of signal, power, and sideband pins the PCIe spec requires. The housing is molded from Polyamide (PA46), a high-temperature nylon that withstands lead-free reflow soldering without warping. The black color is standard for PCIe slots and helps with visual inspection during assembly.
Contact Plating and Mechanical Retention
The contact base metal is phosphor bronze, with a tin plating on the solder tail for good wetting during wave or selective soldering. These mechanical features are standard on PCIe slots and are non-negotiable for reliable operation in a desktop or server environment.
PCI Express Compatibility and Card Thickness
The cantilever contacts are designed to wipe the card edge pads with a controlled normal force that stays within the PCI-SIG specification across the full thickness tolerance. While the evidence does not explicitly state PCIe 3.0 compliance, the 1.00mm pitch, 64-position layout, and 0.062" card thickness are the physical parameters that define the PCIe slot interface — any PCIe card meeting those dimensions will mate correctly.
It is a current-production TE Connectivity part, not a last-time-buy or obsolete line. The base product number is 1734774, and this specific variant is the 64-position, through-hole, gold-plated version in black PA46.
