Samtec SEAM Series Straight Surface Mount PCB Header 400 Contacts 1.27mm Pitch 10 Row Shrouded SEAM-40-09.0-S-10-2-A-K-TR

The Samtec SEAM-40-09.0-S-10-2-A-K-TR is a high-speed, high-density PCB header series designed for advanced electronic applications where robust signal integrity, compactness, and durable interconnect are required. With a total of 400 contacts arranged in a 10-row shrouded configuration, this surface mount header allows for efficient board-to-board connections in dense circuit designs.

This connector features a 1.27mm pitch, optimizing space utilization while maintaining secure alignment and engagement during assembly. Its liquid crystal polymer insulation housing provides both mechanical strength and high thermal resistance, making it suitable for environments with significant temperature variations between -55°C and 125°C. The use of copper alloy for the contacts, finished with a combination of silver and tin plating, delivers long-lasting electrical reliability and protection against oxidation or corrosion.

The shrouded design improves both alignment and connector mating integrity, reducing mechanical stress risks on the contacts and ensuring consistent signal transmission. With a current handling capability of up to 2.7A at 240V, this header is well-suited for a wide variety of signal and low-to-mid power distribution tasks in industrial control systems, telecommunications hardware, instrumentation, and sophisticated PCB assemblies.

Surface mount solder terminations are provided for compatibility with modern automated PCB assembly techniques, resulting in strong and repeatable connections during pick-and-place processing and reflow soldering.

Applications for the SEAM-40-09.0-S-10-2-A-K-TR include high-density logic interfacing, modular industrial devices, communication equipment, embedded controllers, and other environments that require reliable board-to-board connectivity within a compact form factor.

Typical industries include electronics manufacturing, telecommunications, control systems, test and measurement instruments, and advanced computing hardware.

For engineers and designers seeking a robust, space-saving PCB header capable of high contact counts and wide operating conditions, the Samtec SEAM series offers an excellent solution that stands up to demanding industrial requirements and emerging electronic standards.
