What are the key features of LSHM-140-06.0-L-DV-A-N-K-TR?
- 40-position hermaphroditic dual-row board-stacking connector on 0.50 mm pitch for ultra-high-density PCB-to-PCB signal routing
- Fixed 6.0 mm stacking height with keyed (K) and dual-voltage (DV) housing prevents mis-mating in multi-rail board stack designs
- Matte tin over nickel contact finish with peg mounting and tape-and-reel packaging supports automated SMT assembly at production scale
What is LSHM-140-06.0-L-DV-A-N-K-TR used for?
The LSHM-140-06.0-L-DV-A-N-K-TR is designed for compact multi-layer board stack designs in mobile devices, wearable electronics, and high-density data acquisition systems where 40 signals must be routed between PCBs separated by exactly 6.0 mm. Its hermaphroditic contact design eliminates the need to manage separate plug and receptacle SKUs, simplifying BOM management in large production runs. The keyed shroud and dual-voltage coding provide mechanical mis-mate protection in modular instrument and avionics test equipment assemblies with multiple identical-looking board stacks.

Frequently Asked Questions
How many signal positions does the LSHM-140-06.0-L-DV-A-N-K-TR provide and what is its contact pitch?
The LSHM-140-06.0-L-DV-A-N-K-TR offers 40 positions arranged in a dual-row configuration on a 0.50 mm contact pitch. This yields a total mated connector body length of approximately 24.7 mm (0.972 inch), enabling 40 individual signal or power connections in a very narrow footprint suitable for high-density mobile and wearable PCB stacks.
What stacking height does the LSHM-140-06.0-L-DV-A-N-K-TR provide and how does this affect inter-board component clearance?
The 6.0 mm stacking height defines the board-to-board separation in the mated assembly. This 6 mm gap provides clearance for SMD components up to approximately 5.5 mm tall on either board surface, accommodating standard 0402–0805 passives, low-profile ICs in QFN or TSOP packages, and most SMD inductors used in power management stages on adjacent boards.
What advantage does the hermaphroditic contact design of the LSHM-140-06.0-L-DV-A-N-K-TR offer over conventional plug-and-receptacle board stacking connectors?
A hermaphroditic contact design means both mating boards carry identical connectors, eliminating the need to stock two separate part numbers (plug vs. receptacle). In a production run of 10,000 board pairs, using a single SKU rather than 2 line items reduces procurement complexity, minimizes inventory of slow-moving halves, and removes the risk of ordering an imbalanced quantity of plugs versus receptacles across a 40-position high-density interface.
How does the dual-voltage (DV) keying on the LSHM-140-06.0-L-DV-A-N-K-TR protect multi-rail board stacks from mis-mating damage?
The DV (dual-voltage) keying feature adds a physical polarization key that makes the LSHM-140-06.0-L-DV-A-N-K-TR incompatible with non-DV variants of the same connector family. In a system with a 3.3 V logic board and a separate 12 V power board, installing the DV keying on the power board stack prevents inadvertent cross-connection, protecting sensitive 3.3 V ICs from 12 V overload during field assembly or maintenance.
