Frequently Asked Questions
How many pins and at what pitch does the LSHM-140-L4.0-S-DV-A-N-K-TR support for board stacking?
The LSHM-140-L4.0-S-DV-A-N-K-TR provides 80 pins at a 0.50 mm pitch in a hermaphroditic board-stacking configuration, enabling high-density signal routing for PCB-to-PCB interconnects in advanced computing, data communications, and networking equipment operating at multi-gigabit data rates.
What stack height does the LSHM-140-L4.0-S-DV-A-N-K-TR provide and what board-spacing applications does it target?
The LSHM-140-L4.0-S-DV-A-N-K-TR provides a fixed 4.0 mm board-to-board stack height, accommodating components, routing layers, and thermal features between stacked PCBs. With 80 pins at 0.50 mm pitch, it suits compact mezzanine assemblies in networking equipment, embedded computing modules, and industrial control systems where precise inter-board spacing is required.
How does the hermaphroditic contact design of LSHM-140-L4.0-S-DV-A-N-K-TR reduce system design complexity?
The LSHM-140-L4.0-S-DV-A-N-K-TR's hermaphroditic contacts allow both mating PCBs to use the same 80-pin connector part, eliminating separate plug and receptacle SKUs. This reduces inventory complexity and sourcing risk in high-volume board-stacking applications for data communications, industrial computing, and embedded platforms requiring reliable signal routing at up to multi-GHz bandwidth.
