What are the key features of LSHM-120-L4.0-F-DV-A-N-K-TR?
- 40-position hermaphroditic Razor Beam™ contacts on 0.50 mm pitch for ultra-high-density board stacking interconnects
- 4.0 mm stacking height enables compact board-to-board assemblies in thin embedded and mobile platforms
- Identical mating design means the same connector serves as both plug and socket, simplifying BOM and assembly
- Optimized for high-speed signal integrity supporting up to 20 GHz frequencies in communications and computing systems
What is LSHM-120-L4.0-F-DV-A-N-K-TR used for?
The LSHM-120-L4.0-F-DV-A-N-K-TR is used in high-density board stacking applications within telecommunications equipment, portable computing devices, and defense electronics where 40 high-speed signal channels must pass between closely-stacked PCBs on a 0.50 mm pitch. The hermaphroditic Razor Beam™ contact design enables flexible board orientation and eliminates the need for separate plug and socket components, reducing inventory complexity. Its 4.0 mm stacking height suits ultra-thin multi-board assemblies in mobile and embedded computing platforms.

Frequently Asked Questions
How many positions does the LSHM-120-L4.0-F-DV-A-N-K-TR have and what pitch does it use?
The LSHM-120-L4.0-F-DV-A-N-K-TR features 40 positions in a dual-row layout on a 0.50 mm pitch with 4.0 mm board stacking height. This hermaphroditic connector supports 40 signal channels for high-speed board-to-board data routing, with identical mating contacts that allow either PCB to use the same connector part.
What signal speeds can the LSHM-120-L4.0-F-DV-A-N-K-TR support in a board stacking application?
The SAMTEC Razor Beam™ LSHM series supports signal frequencies up to 20 GHz, enabling multi-gigabit SerDes, PCIe, and high-speed differential interface routing in board stacking assemblies. The 0.50 mm pitch minimizes trace stubs and crosstalk, maintaining signal integrity across all 40 channels in dense communication and embedded computing designs.
Why choose the hermaphroditic LSHM-120-L4.0-F-DV-A-N-K-TR over a traditional plug-and-socket mezzanine connector pair?
With hermaphroditic contacts, both mating PCBs use the LSHM-120-L4.0-F-DV-A-N-K-TR, halving the number of unique part numbers to manage and stock. This simplifies procurement for designs needing 40 channels on a 0.50 mm pitch, reduces assembly errors, and eliminates lead time risk compared to sourcing matched plug-and-socket pairs from separate connector manufacturers.
