The TE Connectivity 2041119-1 is a 52-position female edge connector built to the PCI Express Mini Card standard. It mates with the edge of a PCIe Mini Card, carrying the 52 gold pads at a 0.80 mm pitch — the standard footprint for this card format.
The 52-position count matches the card edge contact pattern exactly; this is not a generic mezzanine connector. Gold flash on the phosphor bronze contacts provides adequate corrosion protection and mating cycle life for the card insertion duty — typically hundreds of cycles. The dual-row readout means the connector contacts both sides of the card edge. The black LCP housing with glass fill handles the reflow temperatures of SMT assembly without distortion.
