What are the key features of LSHM-140-02.5-H-DV-A-S-K-TR?
- 80-position hermaphroditic design at 0.50 mm pitch enables same-connector mating for flexible board-stacking configurations
- Shielded construction (S designation) reduces EMI and crosstalk for high-speed differential signal pairs in dense layouts
- Gold-over-nickel contact finish on both mating and termination surfaces ensures reliable low-resistance connection over repeated mating cycles
What is LSHM-140-02.5-H-DV-A-S-K-TR used for?
The LSHM-140-02.5-H-DV-A-S-K-TR is deployed in high-speed board-to-board interconnects within communications equipment, high-performance computing modules, and test and measurement instruments that require 80-channel shielded differential signal routing. Its 0.50 mm pitch hermaphroditic design allows the same connector to be mounted on both mating boards, simplifying inventory management. Design engineers rely on this Razor Beam series for applications demanding sub-millimetre pitch with controlled impedance.

Frequently Asked Questions
How many positions and what pitch does the LSHM-140-02.5-H-DV-A-S-K-TR support for high-speed interconnects?
The LSHM-140-02.5-H-DV-A-S-K-TR provides 80 positions at a 0.50 mm pitch in a hermaphroditic board stacking configuration. This fine pitch and high contact count make it suitable for dense high-speed differential signal pairs in communications modules, where 80 contacts carry multiple SerDes lanes or LVDS pairs between stacked PCBs.
What benefit does the hermaphroditic contact design offer compared to a traditional header-and-socket pair?
A hermaphroditic connector uses an identical part on both mating boards, eliminating separate male header and female socket SKUs. For the LSHM-140 series at 0.50 mm pitch, this means engineers order a single part number for both PCBs, reducing BOM lines and minimising incorrect pairing risk during assembly. The design also allows flexible board orientation since either side can serve as the plug or receptacle.
What role does the shielding (S designation) in LSHM-140-02.5-H-DV-A-S-K-TR play in high-speed signal integrity?
The S (shielded) designation indicates an integrated shield structure around the connector contacts. At 0.50 mm pitch with 80 positions, crosstalk between adjacent signal pairs is a primary concern for multi-gigabit SerDes or LVDS differential channels. The shield reduces inter-pair electromagnetic coupling, lowering crosstalk by several dB compared to unshielded variants, and helps maintain signal eye integrity at data rates above 1 Gbps per differential pair.
