PCIe Mini Card Edge Receptacle
The TE Connectivity 2041262-1 is a 52-position female edge-card receptacle designed for PCI Express Mini Card interfaces.
Position Layout and Board Fit
The 52 positions are split across two rows with a staggered pinout: 18 contacts in one row and 8 in the other, plus additional edge-finger positions that complete the full card interface. The 0.80mm pitch keeps the connector compact — the board footprint requires a tight routing channel, but it matches the standard PCIe Mini Card edge-finger layout exactly.
Contact and Material Choices
Phosphor bronze contacts with gold flash plating handle the moderate mating cycle count typical of a card-edge application — enough for field-service swaps but not designed for daily hot-plug cycles. The LCP glass-filled insulator provides the dimensional stability needed for the 0.80mm pitch and holds up to lead-free reflow profiles.
