ExpressCard

Duel Systems’ ExpressCard enclosures and connectors were developed as the next generation PC card by the PCMCIA Standards Organization. The cards offer a smaller and faster alternative to current PCMCIA cards. The ExpressCard is expected to soon become the new standard for portable devices used in both laptop and desktop computers. Duel manufactures ExpressCard enclosures and connectors and provides standard and custom designs in the ExpressCard format.

The ExpressCard is available in two sizes. The ExpressCard 34 is about half the size of a standard PCMCIA card and the ExpressCard 54 is slightly smaller than a standard card. Both cards are 5mm thick and can be fitted with extended backs for use with antennas or applications where additional space is needed. Both ExpressCard sizes will fit into a universal slot with one common connector size.
