Key Features
- Shielded construction reduces EMI between stacked boards, critical for RF-sensitive or high-speed signal applications
- Hermaphroditic contact gender allows the same connector to mate with itself, simplifying inventory management for stacked assemblies
- Peg mounting option provides mechanical keying and PCB retention during board stacking and handling
Applications
The LSHM-110-02.5-L-DV-A-S-K-TR is used in high-speed board stacking applications where EMI shielding is required between adjacent PCBs in enclosed RF or data communication equipment. Its 2.5 mm stacking height suits compact embedded modules, wireless communication sub-boards, and modular industrial controllers where a shielded 20-pin interface carries both signal and power between stacked layers. The tape-and-reel packaging supports automated assembly for volume production.

Frequently Asked Questions
What stacking height does the LSHM-110-02.5-L-DV-A-S-K-TR provide and how many positions does it carry?
The LSHM-110-02.5-L-DV-A-S-K-TR provides a 2.5 mm board-to-board stacking height with 20 contact positions (10 per row in a dual-row arrangement). The compact 2.5 mm stack clearance is designed for ultra-thin module assemblies where minimal inter-board spacing is required, such as RF daughtercard attachments in wireless communication equipment.
How does the shielded design of the LSHM-110-02.5-L-DV-A-S-K-TR reduce EMI in stacked PCB systems?
The LSHM-110-02.5-L-DV-A-S-K-TR incorporates metal shielding around the contact body, reducing electromagnetic interference radiated or coupled through the connector between stacked PCBs. This shielding is particularly effective for high-speed digital signals above 1 GHz or for RF modules operating in the 2.4 GHz or 5 GHz ISM bands, where unshielded connectors would degrade signal integrity and increase noise floor.
What advantage does the hermaphroditic contact design of the LSHM-110-02.5-L-DV-A-S-K-TR offer in modular PCB stacking?
Hermaphroditic contacts mean the LSHM-110-02.5-L-DV-A-S-K-TR uses the same connector on both the top and bottom PCBs in a stack, eliminating the need to stock a separate male and female variant. This reduces BOM complexity and inventory cost for modular systems using interchangeable boards, and ensures correct mating orientation through the connector's symmetric design with tin-over-nickel termination contacts.
What body dimensions does the LSHM-110-02.5-L-DV-A-S-K-TR have and how does it compare in footprint to wider-pitch board stacking connectors?
The LSHM-110-02.5-L-DV-A-S-K-TR has a body length of 0.382 inch (9.7 mm), breadth of 0.196 inch (5.0 mm), and depth of 0.156 inch (4.0 mm). This footprint is significantly smaller than standard 2.54 mm pitch 20-pin dual-row connectors, which typically exceed 12 mm in length, making the LSHM series preferable for high-density PCB layouts in compact form-factor designs.
