What are the key features of LSHM-140-04.0-L-DV-A-N-TR?
- 80-position dual-row board stacking connector at 4.0 mm stack height enables precise board separation in dense multi-board assemblies
- Gold-plated mating contacts with nickel barrier provide low contact resistance and corrosion resistance for high-reliability signal integrity
- PEG board mounting option delivers superior mechanical retention strength against vibration and shock in demanding environments
What is LSHM-140-04.0-L-DV-A-N-TR used for?
The LSHM-140-04.0-L-DV-A-N-TR is designed for high-density board-to-board stacking in compact embedded computing modules, FPGA mezzanine cards, and high-speed communications blades where 80 signals must span a precise 4.0 mm board separation. The gold mating contacts maintain reliable electrical performance across thousands of mating cycles, making it a strong choice for hot-swap compute modules and removable I/O daughtercards. PEG retention keeps the connector seated under vibration in mil-aero and industrial control chassis applications.

Frequently Asked Questions
What stack height and contact count does LSHM-140-04.0-L-DV-A-N-TR provide for board stacking applications?
The LSHM-140-04.0-L-DV-A-N-TR provides a 4.0 mm board-to-board stack height with 80 total contacts arranged in 2 rows at 0.050-inch (1.27 mm) pitch. This combination allows engineers to pass 80 signals between two boards separated by exactly 4.0 mm, accommodating component height clearances on the mating board.
Why does the gold mating finish on LSHM-140-04.0-L-DV-A-N-TR matter for high-cycle or high-frequency applications?
The SAMTEC LSHM-140-04.0-L-DV-A-N-TR uses a gold contact finish on the mating interface, which maintains contact resistance below a few milliohms even after hundreds of mating cycles and resists oxidation in humid environments. For high-speed signals above 1 GHz, stable low-resistance contacts directly reduce insertion loss and reflections compared to tin-finished alternatives.
How does the PEG board mounting option on LSHM-140-04.0-L-DV-A-N-TR improve mechanical reliability versus standard SMT-only connectors?
The PEG mounting pegs on the LSHM-140-04.0-L-DV-A-N-TR anchor the connector body into drilled holes in the PCB, providing mechanical retention that resists up to several Newtons of pull-out or side-load force beyond what SMT solder pads alone can provide. This is critical in chassis assemblies subject to 5G to 500G shock profiles where unmated connectors can cause intermittent failures.
