Frequently Asked Questions
What stacking height and position count does the LSHM-140-04.0-F-DV-A-S-K-TR support?
The LSHM-140-04.0-F-DV-A-S-K-TR provides a 4.0 mm board stacking height with 40 positions, combining hermaphroditic contacts and the Razor Beam shielded system for high-speed signal integrity in compact mezzanine assemblies.
How does the hermaphroditic contact design of the LSHM-140-04.0-F-DV-A-S-K-TR simplify system procurement?
The hermaphroditic design means the same connector part is used on both the motherboard and daughter card sides, eliminating the need to stock separate male and female components. This reduces BOM complexity and potential mating errors in 40-position stacking connector applications.
What is the factory lead time for the LSHM-140-04.0-F-DV-A-S-K-TR?
The LSHM-140-04.0-F-DV-A-S-K-TR has a factory lead time of approximately 6 weeks and 5 days, so production teams planning high-speed board stacking assemblies should factor this into their procurement schedules to avoid delays.
In which high-speed applications does the Razor Beam shielded system of this connector provide a performance advantage?
The Razor Beam shielded system benefits applications running high-frequency signals such as multi-gigabit serial links, PCIe, or high-speed parallel buses, where the 40-position shielded connector reduces crosstalk and EMI between signal pairs at the 4.0 mm stacking interface.
