What are the key features of LSHM-140-L1-L-DH-A-S-K-TR?
- 80-position hermaphroditic contacts at 0.50 mm pitch enable both plug and receptacle function from a single part, simplifying inventory for board stacking designs
- Razor Beam high-speed contact design supports signal integrity at multi-gigabit data rates with gold-plated mating surfaces
- Dual-height ('DH') body with peg board mounting, keying ('K'), and tape-and-reel ('TR') packaging enables automated SMT assembly with secure mechanical registration
What is LSHM-140-L1-L-DH-A-S-K-TR used for?
The LSHM-140-L1-L-DH-A-S-K-TR is designed for high-speed board-to-board stacking in advanced computing, FPGA carrier boards, network switches, and SDR platforms where 80 signals must be routed between stacked PCBs at 0.50 mm pitch with multi-gigabit signal integrity. Its hermaphroditic contacts allow the same part to serve as both the plug and receptacle, reducing component SKUs in modular system architectures.

Frequently Asked Questions
What does hermaphroditic contact design mean for the LSHM-140-L1-L-DH-A-S-K-TR and why is it useful in stacking systems?
Hermaphroditic contacts mean a single LSHM-140-L1-L-DH-A-S-K-TR part acts as both plug and receptacle — two identical connectors mate with each other. In a modular board stacking system with 80-position stacking requirements, this eliminates the need to stock and manage separate plug and receptacle SKUs, reducing supply chain complexity and minimum order quantities for both sides of the board-to-board pair.
What signal speeds can the LSHM-140-L1-L-DH-A-S-K-TR Razor Beam connector support in high-speed digital applications?
SAMTEC's Razor Beam series is characterized for multi-gigabit differential signaling. The LSHM-140-L1-L-DH-A-S-K-TR at 0.50 mm pitch with gold-plated mating contacts supports signal integrity for protocols such as PCIe Gen 3 (8 Gbps per lane), USB 3.1, and high-speed LVDS interfaces. Actual channel bandwidth depends on PCB stack-up, trace length, and stacking height selected from the DH body options.
How do the 'K' keying feature and peg board mounting of the LSHM-140-L1-L-DH-A-S-K-TR improve assembly reliability?
The 'K' key prevents misaligned mating of the 80-position connector at 0.50 mm pitch, where a single pin offset would short adjacent signals and damage the PCB. The peg board mounting feature anchors the connector body mechanically to the PCB through mounting pegs before soldering, maintaining precise position during reflow and preventing the 0.50 mm pitch contacts from floating during solder paste reflow at 260°C peak temperature.
When would a design team choose the LSHM-140-L1-L-DH-A-S-K-TR over a 0.80 mm or 1.00 mm pitch 80-position board stacking connector?
The LSHM-140-L1-L-DH-A-S-K-TR at 0.50 mm pitch fits 80 positions in a 0.982 inch body length, whereas the same 80 positions at 1.00 mm pitch would require approximately 1.97 inches. Teams targeting compact stacking modules with PCB widths under 25 mm and requiring high-speed differential pairs should choose the 0.50 mm pitch Razor Beam over wider-pitch alternatives when board dimensions are constrained.
