Frequently Asked Questions
What is the stack height provided by the SEAF-40-05.0-L-06-2-A-K-TR and why does it matter for board stacking designs?
The SEAF-40-05.0-L-06-2-A-K-TR provides a 5.0 mm board-to-board stack height, which determines the vertical clearance between two mated PCBs. This fixed 5.0 mm spacing must match the mating SEAM plug connector stack height to ensure proper mating and avoid mechanical stress on solder joints.
How many signal positions does the SEAF-40-05.0-L-06-2-A-K-TR support, and what contact finish is used on the mating interface?
This connector features 40 positions for signal routing between stacked boards. The mating contacts are finished with gold (10 µin minimum) over nickel, providing low contact resistance, excellent corrosion resistance, and reliable electrical continuity across thousands of mating cycles in demanding applications.
Is the SEAF-40-05.0-L-06-2-A-K-TR compatible with lead-free reflow soldering, and what is the typical factory lead time?
Yes, this connector is Pb-free and RoHS-compliant, making it fully compatible with standard lead-free reflow soldering processes. The factory lead time is approximately 1 week, which supports fast prototyping schedules and production builds that cannot tolerate long procurement delays.
In which industrial or embedded computing applications is the SEAF-40-05.0-L-06-2-A-K-TR typically deployed?
The SEAF-40-05.0-L-06-2-A-K-TR is used in industrial control modules, modular embedded computing platforms, telecommunications line cards, and sensor array systems where two PCBs must be stacked at a 5.0 mm height with 40 signal connections. Its gold contacts make it suitable for test fixtures requiring repeated mating cycles exceeding 100 insertions.
