Connectors Put Memory Cards In Touch With Portables

Serving to link Secure Digital (SD) memory cards to digital portable products such as PDAs, cell phones, digital cameras and portable audio players, these new, nine-circuit connectors come in top- and bottom-mount styles and can accept cards packing as much as 64 MB of flash memory. The connectors also contain card detect and wire-protect switch functions to enable secure downloading of digital data, such as audio or image files.
Other key features of the SD card connectors include a 3.1-mm height, metal-grounding cover for ESD protection, offset terminals for first make/last break capabilities, and a unique "push-push" ejection system that allows the postage stamp-size cards to be securely retained in and easily inserted into and extracted from the portable products.
The 2.5-mm pitch connectors are rated at 0.5A and can withstand up to 10,000 mating/unmating cycles. And they are packaged on embossed tapes and cost about $2.50, depending on model and quantity ordered.
