Key Features
- 80 positions at 0.50 mm pitch Razor Beam high-speed contact system for dense, low-profile board-to-board signal routing
- 4.0 mm stacking height hermaphroditic design eliminates separate plug and socket SKUs, simplifying BOM management for stacked PCB assemblies
- Peg-mount mechanical retention and tape and reel packaging ensure stable board anchoring and automated pick-and-place compatibility
Applications
LSHM-140-04.0-F-DV-A-N-K-TR is used in high-speed board stacking applications within embedded computing modules, communication blades, and instrumentation platforms where 80 signals must be routed between boards separated by exactly 4.0 mm. Its 0.50 mm pitch Razor Beam contacts support high-frequency differential pair routing while the hermaphroditic design reduces connector inventory complexity.

Frequently Asked Questions
What pitch, position count, and stacking height does LSHM-140-04.0-F-DV-A-N-K-TR specify?
LSHM-140-04.0-F-DV-A-N-K-TR provides 80 positions at 0.50 mm pitch with a 4.0 mm board stacking height. The 0.50 mm pitch Razor Beam contact system enables high-density differential signal routing, while the 4.0 mm fixed stacking height accommodates SMD component clearance on the inner board surfaces in compact multi-board assemblies.
How does the hermaphroditic contact of LSHM-140-04.0-F-DV-A-N-K-TR reduce BOM complexity?
The hermaphroditic contact means both mating boards use the identical LSHM-140-04.0-F-DV-A-N-K-TR part number — no separate plug and receptacle SKUs are needed. For a 4.0 mm stacked assembly with 80 positions, engineers manage a single line item for both boards, cutting procurement overhead and reducing risk of mismating opposite-gender connectors during assembly.
What are the body dimensions of LSHM-140-04.0-F-DV-A-N-K-TR for PCB keep-out planning?
LSHM-140-04.0-F-DV-A-N-K-TR has a body length of 0.972 inch (24.7 mm), depth of 0.215 inch (5.46 mm), and breadth of 0.196 inch (4.98 mm). Combined with peg-mount retention features and the 4.0 mm stacking height, these dimensions define the mechanical keep-out zone required on both PCBs in the stacked assembly for correct clearance and reliable mating.
