Frequently Asked Questions
What data rate can the LSHM-140-02.5-F-DV-A-N-TR support per differential pair, and what applications benefit most?
The LSHM-140-02.5-F-DV-A-N-TR uses Samtec's Razor Beam technology supporting up to 40 Gbps per differential channel. This makes it well-suited for PCIe Gen 4/5 mezzanine cards, 100G Ethernet line cards, and FPGA-based accelerator boards where high-bandwidth inter-board communication in compact 2.5 mm stacking height is essential.
How does the hermaphroditic contact design of the LSHM-140-02.5-F-DV-A-N-TR simplify board stacking inventory management?
Because both mating halves of the LSHM-140-02.5-F-DV-A-N-TR use identical hermaphroditic contacts, designers need only one part number for both sides of a board stack rather than separate male and female connectors. This reduces SKU count, simplifies procurement, and eliminates mis-mating risk for the 80-position, 0.50 mm pitch interface in production assembly.
For a compact server blade requiring precise board gap control, how does the 2.5 mm stacking height of this connector compare to alternatives?
At 2.5 mm board-to-board stacking height, the LSHM-140-02.5-F-DV-A-N-TR is among the lowest-profile high-speed board stacking solutions available at 0.50 mm pitch. Competing alternatives at similar density often require 3 mm to 5 mm stacking heights, making this connector advantageous for 1U server blades and ultra-thin mezzanine form factors where every 0.5 mm of vertical clearance matters.
