Key Features
- 80-position, 0.50 mm pitch hermaphroditic contact design eliminates separate plug/receptacle pairing, simplifying stacked PCB inventory and assembly
- 3.0 mm (L3.0) board-to-board stack height provides precise mezzanine separation in space-constrained high-density server and telecom designs
- Razor Beam contact technology delivers controlled-impedance, high-frequency signal transmission across all 80 positions in multi-GHz board stacking applications
Applications
The LSHM-140-L3.0-S-DV-A-N-K-TR is engineered for high-speed board stacking in server accelerator cards, high-bandwidth data acquisition modules, and advanced telecom line cards where 80 hermaphroditic contacts must be routed at 0.50 mm pitch within a tightly controlled 3.0 mm stack height. The hermaphroditic form factor reduces part count by eliminating distinct plug and receptacle SKUs, streamlining procurement and assembly for paired board assemblies. Tape-and-reel packaging enables efficient automated pick-and-place production in high-volume SMT manufacturing environments.

Frequently Asked Questions
What does the hermaphroditic contact design of the LSHM-140-L3.0-S-DV-A-N-K-TR mean for paired board assemblies?
The hermaphroditic design makes both mating halves identical, each carrying 80 contacts at 0.50 mm pitch, so engineers stock only one SKU instead of separate plug and receptacle parts, simplifying procurement and reducing the risk of assembly errors in stacked PCB builds.
What board separation does the L3.0 designation set for the LSHM-140 Razor Beam connector?
The L3.0 suffix specifies a 3.0 mm board-to-board stack height, giving designers precise control over the gap between two mating PCBs while routing 80 high-speed signals at 0.50 mm pitch through the Razor Beam hermaphroditic interface in compact mezzanine assemblies.
Which high-frequency applications commonly specify the LSHM-140-L3.0-S-DV-A-N-K-TR Razor Beam connector?
This 80-position, 0.50 mm pitch hermaphroditic connector is specified in server accelerator modules, high-bandwidth data acquisition cards, and telecom line card assemblies where multi-GHz differential signals must cross a 3.0 mm board-to-board interface at maximum signal density.
