Key Features
- 40-position dual-row 2.00 mm pitch board stacking connector with 6 mm stack height for robust mezzanine board-to-board interconnection
- Matte tin over nickel contact finish on both mating and termination surfaces, providing reliable electrical connection with RoHS-compliant plating
- Integrated peg mounting posts ensure precise board-to-board alignment and mechanical retention during and after reflow soldering
Applications
The SEAM-40-02.0-L-06-2-A-GP-K-TR is designed for mezzanine and daughtercard stacking in embedded computing, industrial control, and communications infrastructure boards where a 40-position 2.00 mm pitch male header mates with a corresponding SEAF or SEAF-GP socket at a controlled 6 mm stack height. The connector is suited for modular radio boards, FPGA expansion cards, and IoT gateway modules where the board stack must fit within a defined vertical envelope. Peg mounting ensures both boards remain coplanar under vibration in harsh environments such as railway or automotive electronics.

Frequently Asked Questions
What are the pin count, pitch, and stack height of the SEAM-40-02.0-L-06-2-A-GP-K-TR?
The SEAM-40-02.0-L-06-2-A-GP-K-TR has 40 positions in a dual-row layout at a 2.00 mm pitch, with a 6 mm board-to-board stack height. This combination is commonly used in embedded system designs where a controlled 6 mm gap between PCBs accommodates components on both boards while maintaining a compact overall assembly height.
How do the peg mounting posts on SEAM-40-02.0-L-06-2-A-GP-K-TR improve assembly reliability?
The integrated peg mounting posts press into matching PCB holes on both boards, providing mechanical registration that keeps all 40 contacts coplanar before and during reflow soldering. In vibration-prone environments such as automotive or industrial equipment, the pegs also transfer shear loads away from the solder joints, extending connector field life significantly.
Which mating socket is compatible with the SEAM-40-02.0-L-06-2-A-GP-K-TR for a 6 mm board stack?
This male header is designed to mate with SAMTEC's SEAF or SEAF-GP series female sockets at the same 2.00 mm pitch and 40-position dual-row configuration, achieving the nominal 6 mm board-to-board spacing. The GP (gold-plated) socket variant is recommended when repeated mating cycles exceed 100 insertions, while the standard matte tin version suits lower-cycle-count mezzanine applications.
Why is matte tin over nickel plating used on SEAM-40-02.0-L-06-2-A-GP-K-TR contacts instead of gold?
Matte tin over nickel provides a cost-effective RoHS-compliant finish that forms reliable solder joints and maintains adequate contact resistance for low-frequency signal and power pins at current levels up to 1 A per contact. Gold plating would add cost without additional benefit for applications where the connector mates only once or a few times during manufacturing, as tin whisker risk is mitigated by the nickel barrier.
