CFast™Memory Delivers Optimum Combination of Size and Speed for Imaging Designs

Demand for higher resolution and increased portability of medical imaging devices continually drive OEMs to develop faster, higher performing and more compact products. For high performance in solid-state removable memory, medical device manufacturers can now utilize CFast, the latest generation flash device architecture developed by the CompactFlash Association, to achieve these goals. 

CFast™ Storage Cards incorporate SATA serial storage architecture and performance into a package equivalent in size to CompactFlash (CF) storage cards.  The move away from a parallel ATA-style interface allows for faster data throughput – up to 3 Gbps with CFast compared to 1.33 Gbps with CF.  They were developed to serve applications where high-resolution images need to be captured at faster data rates, such as medical imaging.

The 3M™ Header for CFast Card N7G24 Series delivers on reliability. They incorporate extended guide rails to help reduce the possibility of misalignment during card installations. Grounding clips provide additional retention force to the card, helping reduce uncontrolled card removal from the connector when ejected.
3M offers optional left or right button dual-push ejectors that provide a balanced force against the card for even and smooth card removal. A unique option for the CFast headers from 3M is a latching retainer, which clips onto the header and provides robust retention in high-vibration environments.

CFast and 3M offer the medical device designer an excellent combination of reliability, size and performance for their demanding product requirements. 

3M Power Clamp Connectors

The 3M Header N7G24 Series meets the CFA CFast Specification Rev 1.0, including the 10,000 mating cycles and 3 Gbps data rate performance.

Other product features include integrated grounding clips and SMT tails aligned in a single row for higher manufacturing yield and simplified inspection.

Similar to the popular 3M™ CF Card Headers, Type II product line, the optional push button ejectors have a dual-push configuration. These ejectors deliver two points of force against the card. The dual-push provides more stability, reducing the chance for the card to rotate and bind during ejection, delivering a more even and smooth card removal.

In addition to the ejectors, the 3M headers for CFast cards have the option of a latching retainer. This accessory provides a wire latch that captures a mated card firmly, making it ideal for high vibration environments or applications where securing the card is critical. The latching retainer may not be used in combination with the ejectors. This same latching retainer will fit on existing 3M CFII headers, N7E50-M516 and N7E50-N516 Series.
