Key Features
- Hermaphroditic contact design allows identical connectors on both boards to mate directly, simplifying inventory management by eliminating separate plug and receptacle SKUs
- Right-angle (RH) orientation with 1.288 inch body length enables horizontal board-edge mating in multi-board system stacking configurations
- Peg board mounting option provides mechanical registration and retention during reflow soldering, improving placement accuracy in automated SMT assembly
- 50-position rectangular contact pattern at high-density pitch supports broad signal and power routing across mating boards in compact embedded system designs
Applications
The LSHM-150-01-F-RH-A-S-TR is designed for mezzanine board stacking and edge-mounted board-to-board interconnects in FPGA evaluation kits, rugged industrial computers, and embedded computing modules where identical connectors on both PCBs simplify system assembly and field replacement. Its right-angle orientation supports horizontal signal routing across stacked boards in server blade architectures and telecom line cards where vertical connector height is limited. The hermaphroditic design and peg alignment feature make it well suited for high-reliability military and aerospace systems requiring consistent mating performance across 50 circuits.

Frequently Asked Questions
What does the hermaphroditic design of the LSHM-150-01-F-RH-A-S-TR mean for inventory and system assembly?
The hermaphroditic design means the LSHM-150-01-F-RH-A-S-TR uses identical contacts and housings on both mating boards, eliminating the need to stock separate male plug and female receptacle variants. This simplifies bill of materials management and reduces the risk of mismatched connector pairs during assembly. A single SKU covers both sides of a 50-position board-to-board interface, reducing procurement complexity in systems with multiple identical mezzanine modules.
How does the right-angle orientation of the LSHM-150-01-F-RH-A-S-TR affect board-to-board stacking configurations?
The right-angle (RH) orientation of the LSHM-150-01-F-RH-A-S-TR positions the mating axis parallel to the PCB surface, enabling edge-to-edge horizontal stacking rather than vertical daughter-card configurations. With a body length of 1.288 inches and body breadth of 0.202 inches, this connector allows two PCBs to be joined side-by-side with the mating forces applied horizontally, reducing the overall vertical stack height in rack-mounted telecom and industrial control equipment.
What role does the peg mounting option play in the LSHM-150-01-F-RH-A-S-TR SMT assembly process?
The peg (PEG) board mounting option on the LSHM-150-01-F-RH-A-S-TR provides mechanical registration by inserting into PCB through-holes before soldering, holding the connector in position during the reflow cycle even without solder paste adhesion. This prevents the 1.288 inch body from shifting under surface tension forces during reflow at peak temperatures of 260°C, maintaining contact pad alignment within ±0.1 mm across all 50 positions and ensuring reliable solder joint formation.
How many circuits does the LSHM-150-01-F-RH-A-S-TR support and what signal types are typical for its 50-position configuration?
The LSHM-150-01-F-RH-A-S-TR provides 50 positions in a rectangular contact pattern, supporting a mix of high-speed differential pairs (such as PCIe or USB 3.0 at up to 10 Gbps per lane), LVDS video interfaces, control signals, and power distribution across the board-to-board interface. At typical contact current ratings of 0.5 A to 1 A per pin, the 50-position layout can deliver up to 10 A of total power while simultaneously routing dozens of signal circuits in demanding embedded computing applications.
