Frequently Asked Questions
How many signal contacts does LSHM-140-L2.5-S-DV-A-N-K-TR provide and what is their maximum bandwidth?
The LSHM-140-L2.5-S-DV-A-N-K-TR routes signals through 80 positions arranged at a 0.50 mm pitch, with the Razor Beam platform supporting differential data rates up to 40 GHz. This combination of high port count and wide bandwidth suits PCIe, Ethernet backplanes, and multi-channel RF digitizer boards demanding both density and signal fidelity.
For which slim mezzanine board designs is the 2.5 mm stack height of LSHM-140-L2.5-S-DV-A-N-K-TR most advantageous?
The 2.5 mm board stack height makes the LSHM-140-L2.5-S-DV-A-N-K-TR ideal for low-profile mezzanine assemblies in 5G radio units, compact avionics line-replaceable units, and ruggedized instrumentation where z-axis clearance is tightly constrained. Its 40 GHz bandwidth simultaneously supports high-speed serial protocols such as PCIe Gen 4 running at 16 GHz, enabling modern compute and communication workloads.
How does the hermaphroditic contact system of LSHM-140-L2.5-S-DV-A-N-K-TR reduce procurement complexity?
Because both mating boards use the identical LSHM-140-L2.5-S-DV-A-N-K-TR part, connector SKU count drops by 50% compared to separate plug-and-receptacle pairs, simplifying supplier qualification and safety-stock planning. Tape-and-reel packaging allows automated pick-and-place machines to install the 80-pin connector at high throughput, lowering per-unit assembly cost in volume production runs.
