Key Features
- 100-position 0.50 mm pitch hermaphroditic terminal/socket design enabling board stacking without a dedicated plug/receptacle pair
- Gold-plated mating contacts for low contact resistance below 20 mΩ and superior high-speed signal integrity above 10 Gbps
- Razor Beam high-speed contact geometry with PEG board mounting for precise alignment and vibration-resistant stacking connections
Applications
The LSHM-150-L1-L-DH-A-S-K-TR is used in high-speed board-stacking applications including FPGA daughter cards, high-bandwidth memory modules, and compute-on-module (CoM) expansion boards that require 100 signals at 0.50 mm pitch with minimal signal skew. Its hermaphroditic contact design allows any two boards with the same connector to mate, simplifying inventory and reducing engineering risk in modular system architectures. The Razor Beam contact geometry supports differential pair routing at data rates up to 25 Gbps per lane, suitable for PCIe Gen 4, USB 3.2, and 100GbE optical transceiver modules.

Frequently Asked Questions
What pitch and pin count does LSHM-150-L1-L-DH-A-S-K-TR provide for board-stacking applications?
The LSHM-150-L1-L-DH-A-S-K-TR provides 100 positions at a 0.50 mm pitch arranged in dual-row hermaphroditic configuration, fitting a body length of 1.179 inch for high-density board-stacking with up to 50 differential pairs in a footprint smaller than 30 mm x 9 mm.
How does the hermaphroditic contact design of LSHM-150-L1-L-DH-A-S-K-TR simplify modular PCB system design?
The hermaphroditic terminal/socket contact means both mating boards use identical LSHM-150-L1-L-DH-A-S-K-TR connectors, eliminating the need to stock separate plug and receptacle parts, which reduces component inventory by 50% and simplifies PCB design for swappable module architectures.
At what data rate can the LSHM-150-L1-L-DH-A-S-K-TR high-speed contacts reliably operate for differential signaling?
The LSHM-150-L1-L-DH-A-S-K-TR Razor Beam contacts are characterized for high-speed differential signals up to 25 Gbps per lane with return loss better than -15 dB up to 15 GHz, supporting PCIe Gen 4 (16 GT/s), USB 3.2 (20 Gbps), and 25GbE interface standards in multi-layer PCB stack-up designs.
How does the Gold contact finish of LSHM-150-L1-L-DH-A-S-K-TR compare to tin-finished alternatives for long-term reliability?
The Gold (Au) mating contact finish of LSHM-150-L1-L-DH-A-S-K-TR provides contact resistance below 20 mΩ and supports over 50 mating cycles without oxidation degradation, versus tin-finished contacts that can develop 50 mΩ to 200 mΩ resistance after 20 cycles in humid industrial environments above 85% RH.
