Frequently Asked Questions
What stack height and contact count does the LSHM-120-04.0-L-DV-A-S-TR support?
The LSHM-120-04.0-L-DV-A-S-TR provides a 4.0 mm board-to-board stack height with 40 total contacts arranged in a dual-row configuration, allowing designers to achieve high-density interconnects in compact mezzanine card assemblies.
Why choose gold mating contacts over tin in high-cycle board stacking applications?
Gold (Au) mating contacts on the LSHM-120-04.0-L-DV-A-S-TR provide lower and more stable contact resistance across hundreds of mating cycles compared to tin finishes; this is especially important in 40-pin board stacking interfaces subject to field servicing or repeated plug-in operations.
Is the LSHM-120-04.0-L-DV-A-S-TR suitable for automated pick-and-place assembly?
Yes. The TR suffix denotes tape-and-reel packaging, compatible with standard SMT pick-and-place machines; the 0.589 inch body length and matte tin termination further support reflow soldering on PCBs requiring 40-position dual-row connectors.
How does lead time impact procurement planning for this SAMTEC connector?
SAMTEC lists a standard factory lead time of 1 week for the LSHM-120-04.0-L-DV-A-S-TR, making it suitable for short-cycle production planning; designers using 40-position stacking connectors in high-volume programs can typically expect rapid replenishment relative to custom-spec connectors.
