DELL OptiPlex 3060 5060 7060 3070 MT SD Card Reader Board Cable 94D86 59MR7 laptop replacement part

Genuine Dell SD Card Reader Kit for OptiPlex MT

This genuine Dell replacement kit restores front-panel SD card functionality to OptiPlex 3060, 5060, 7060 and 3070 Mini Tower desktops. It includes the reader board (part 94D86) and the internal ribbon cable (part 59MR7) required for a complete installation. The part is designed for owners who need to read or write standard SD, SDHC and SDXC media directly at the front I/O panel. It is not suitable for small-form-factor, micro or all-in-one OptiPlex chassis.

Installation Uses OEM Bracket and Header Connection

The board mounts into the dedicated front-panel bracket using the original screw points and connects to the motherboard via an internal header. Builders should verify the header pin-out matches their specific motherboard revision before fitting the cable. A common issue is routing the flat ribbon cable through the chassis clips without kinking it, which can break the conductors. No additional drivers are required beyond the standard Windows storage stack.

Sustained Transfers Limited by SD Card Specification

Under continuous read or write workloads the throughput is governed by the inserted SD card's speed class and the USB-attached controller behind the header. The board itself adds no active cooling, so prolonged heavy I/O will not throttle the component but will reflect the media's own sustained-rate ceiling. Users moving large batches of RAW images or video files should expect performance consistent with the card's rated sequential figures rather than burst peaks.
