What are the key features of LSHM-140-L2.5-F-DV-A-N-K-TR?
- 80 pins in a hermaphroditic configuration at 0.50 mm pitch deliver very high connection density in a compact mezzanine footprint
- Controlled 2.5 mm stack height enables precise, low-profile board-to-board separation for tight chassis and enclosure designs
- Razor Beam high-speed contact technology supports signal frequencies above 10 GHz for multi-gigabit serial and high-bandwidth digital interfaces
- Single hermaphroditic part used on both host and daughter board simplifies procurement and reduces inventory SKU count
What is LSHM-140-L2.5-F-DV-A-N-K-TR used for?
The LSHM-140-L2.5-F-DV-A-N-K-TR is designed for high-speed mezzanine board-stacking in FPGA daughter-card modules, server compute blades, radar sub-assemblies, and portable medical instruments where 80 hermaphroditic signal connections must be maintained at a precise 2.5 mm board separation. Its Razor Beam contact technology supports high-bandwidth signals above 10 GHz, making it suitable for systems carrying multi-gigabit serial interfaces between stacked PCBs. Tape-and-reel packaging enables automated pick-and-place integration into high-volume stacked-module production processes.

Frequently Asked Questions
What contact count, pitch, and stack height does the LSHM-140-L2.5-F-DV-A-N-K-TR provide for mezzanine designs?
The LSHM-140-L2.5-F-DV-A-N-K-TR provides 80 pins in a hermaphroditic arrangement at a fine 0.50 mm pitch with a controlled 2.5 mm board-to-board stack height. This combination achieves very high signal density per unit of board area while maintaining a precise, repeatable separation between mated PCBs in compact multi-board module assemblies.
Which high-speed digital and RF mezzanine applications is the LSHM-140-L2.5-F-DV-A-N-K-TR Razor Beam designed for?
The Razor Beam contacts in the LSHM-140-L2.5-F-DV-A-N-K-TR are engineered for FPGA daughter cards, multi-gigabit serial backplanes, compact radar modules, and server blade interconnects where signal integrity at frequencies above 10 GHz must be maintained across all 80 pins. The 2.5 mm controlled stack height fits within the tight board-spacing envelopes of 1U rack-mount and small-form-factor embedded systems.
How does the hermaphroditic contact design of the LSHM-140-L2.5-F-DV-A-N-K-TR reduce procurement and inventory complexity?
Because the LSHM-140-L2.5-F-DV-A-N-K-TR uses the identical hermaphroditic part on both host and daughter boards, a production BOM requires only one connector MPN to populate all 80-pin mating positions in a stacked assembly. This single-SKU approach reduces the risk of mismatched gender sourcing errors and simplifies both engineering change orders and production inventory management for multi-board stacked modules.
When is the LSHM-140-L2.5-F-DV-A-N-K-TR at 0.50 mm pitch preferred over a 1 mm pitch board-stacking connector?
The 0.50 mm pitch of the LSHM-140-L2.5-F-DV-A-N-K-TR is chosen over 1 mm pitch alternatives when fitting 80 pins into a footprint too small for a 1 mm pitch connector, or when differential signal frequencies above 10 GHz per lane demand the shorter contact stub lengths achievable at finer pitch. The 2.5 mm controlled stack height also permits tighter board-to-board spacing than most 1 mm pitch connectors carrying an equivalent 80-pin signal count.
