What are the key features of LSHM-140-04.0-S-DV-A-N-K-TR?
- 80-position hermaphroditic design at 0.50 mm pitch enables high-density board-to-board stacking with one common connector part
- Razor Beam™ contact technology supports high-frequency signal transmission with minimal insertion loss and skew
- 4.0 mm mated stack height accommodates tight PCB spacing in compact electronic assemblies
- Board peg mounting option provides mechanical retention and alignment precision during reflow assembly
What is LSHM-140-04.0-S-DV-A-N-K-TR used for?
The LSHM-140-04.0-S-DV-A-N-K-TR is designed for high-speed board-to-board stacking in portable medical devices, industrial instrumentation, and consumer electronics where a 4.0 mm stack height and 0.50 mm pitch minimize form factor while maintaining signal integrity. Its hermaphroditic contact design simplifies BOM management by using the same 80-pin connector on both mating boards. This board stacking connector also serves telecommunications modules and ruggedized embedded computing platforms requiring high-speed contacts in a space-constrained layout.
