Frequently Asked Questions
How does the hermaphroditic contact design of LSHM-120-L3.0-H-DV-A-N-K-TR simplify board stack assembly?
Because LSHM-120-L3.0-H-DV-A-N-K-TR uses a hermaphroditic design, the same 40-pin part is used on both the top and bottom PCB in a stack — no distinct plug and receptacle are needed. This reduces the number of unique SKUs to manage and eliminates mating polarity errors during board assembly.
How does the 3.0 mm stack height of LSHM-120-L3.0-H-DV-A-N-K-TR compare to LSHM-140-L6.0 for tight enclosures?
LSHM-120-L3.0-H-DV-A-N-K-TR provides a 3.0 mm mated board separation versus 6.0 mm for the LSHM-140-L6.0, making it preferable when enclosure depth or component height between boards is tightly constrained. The 40-pin contact count also suits lower-channel-count interfaces compared to the 80-pin LSHM-140 series.
For a compact computing mezzanine needing 40 high-speed signals, what performance does LSHM-120-L3.0-H-DV-A-N-K-TR deliver?
The 40-pin LSHM-120-L3.0-H-DV-A-N-K-TR carries high-speed differential and single-ended signals at multi-gigabit data rates using Razor Beam contacts at 0.50 mm pitch, supporting interfaces like PCIe, LVDS, or MIPI in a compact 14.7 mm body length. The 3.0 mm inter-board gap keeps the combined stack profile within most compact computing enclosure constraints.
