Key Features
- 100-position hermaphroditic contact design eliminates separate male/female inventory, simplifying procurement for symmetric board stacking
- 0.50 mm pitch with 3.0 mm stack height enables ultra-compact board-to-board interconnects in space-constrained multi-PCB assemblies
- Gold-plated mating contacts with nickel barrier provide low contact resistance and high reliability over thousands of mating cycles
- Tape-and-reel (TR) packaging and peg mounting option support high-volume automated SMD assembly with precise board alignment
Applications
The LSHM-150-03.0-L-DV-A-N-K-TR is designed for board-to-board stacking in high-density embedded computing modules, communication mezzanine cards, and compact medical device electronics where 100 signal lines must be routed between two PCBs separated by only 3.0 mm. Its hermaphroditic contact design and dual-voltage polarized housing allow symmetric board layouts without a dedicated plug/receptacle distinction. Server blade interconnects, module expansion cards, and portable diagnostic equipment are typical end applications.

Frequently Asked Questions
What stack height and pin count does the LSHM-150-03.0-L-DV-A-N-K-TR provide for board-to-board connections?
The LSHM-150-03.0-L-DV-A-N-K-TR offers a 3.0 mm board-to-board stack height with 100 positions at 0.50 mm pitch, arranged in a dual-row hermaphroditic configuration with 50 pins per row. This combination allows 100 signal or power lines to cross between two PCBs separated by 3.0 mm, suitable for compact mezzanine and module-on-module stack architectures.
How does the hermaphroditic contact design of LSHM-150-03.0-L-DV-A-N-K-TR simplify procurement compared to matched plug-and-receptacle connector pairs?
A hermaphroditic design uses identical connectors on both the carrier and mezzanine boards, meaning only one part number is needed instead of two. This halves the SKU count in the BOM and eliminates the risk of ordering mismatched plug/receptacle combinations, which is especially valuable in high-mix embedded module programs where multiple board combinations share the same 100-position 0.50 mm pitch interface.
For a compact medical device PCB stack, how does the 3.0 mm stack height of LSHM-150-03.0-L-DV-A-N-K-TR affect overall device thickness?
In a two-board medical device stack, the LSHM-150-03.0-L-DV-A-N-K-TR's 3.0 mm mated height contributes only 3.0 mm to the board separation, allowing a total stack thickness (including both PCBs at 1.0 mm to 1.6 mm each) of approximately 5.0 mm to 6.2 mm. This is significantly thinner than standard 0.100" pitch stacking connectors at 8.5 mm to 11.0 mm mated height, enabling slimmer portable diagnostic and wearable device designs.
What contact finish does LSHM-150-03.0-L-DV-A-N-K-TR use and how does it affect connector reliability?
The mating contacts use gold (Au) plating over a nickel (Ni) barrier, which provides a contact resistance typically below 20 mΩ per contact and ensures stable electrical performance over thousands of mating cycles. Gold plating prevents the oxidation and fretting corrosion that affect tin-plated contacts in environments with vibration or frequent mating, making the LSHM-150-03.0-L-DV-A-N-K-TR suitable for removable module applications requiring long service life.
