Application Field and Working Principle of SEAM-40-02.0-S-08-2-A-K-TR

SEAM-40-02.0-S-08-2-A-K-TR is a type of rectangular connectors - arrays, edge type, mezzanine (board to board). It is designed for high-speed signal transmission and power distribution. The connector is designed to fit onto the edge of a printed circuit board (PCB), allowing for easy connection between components mounted onto the board. It is commonly used in application such as communication systems, computer systems, servers, semiconductors, and other industrial markets, to facilitate data transfer between PCBs and other electrical equipment.

Design Features

The SEAM-40-02.0-S-08-2-A-K-TR connector features a high-density, low-profile design suitable for use in tight spaces. It has a total of 40 pins arranged in twelve rows of 15 pins per row, and 8 signal contact positions. Its contact pitch is 2.0mm, which is the distance between centerlines of adjacent pins. Its contact size is 0.6mm and insulation height is 2.6mm, allowing for easy soldering for large and small parts and allowing greater flexibility in PCB layout.

Contact Configuration

The pins in the SEAM-40-02.0-S-08-2-A-K-TR connector are arranged in a straight line, arranged in two sets of 20; the first set of 20 pins are signal contacts and are used to connect electrical signals between PCBs. The second set of 20 pins are power contacts, which are used to transmit power to the devices connected to the board. The power contacts can be used to supply up to 8A of current.

Material and Plating

The contact pins of the SEAM-40-02.0-S-08-2-A-K-TR connector are made from high-quality phosphor bronze, with an average thickness of 0.25mm. The connector body is made from a light-weight, thermoplastic material and is designed for durability. The connector also features a gold-plated finish and is resistant to oxidation.

Performance

The SEAM-40-02.0-S-08-2-A-K-TR connector features an operating temperature range of -25 to 85°C and the contact pins can perform up to Reflow 280°C. It has a rated current of 8A and an insulation resistance of 500Mohm for signal contacts and 500V for power contacts. The contact resistance is 25mΩ for signal contacts and 10mΩ for power contacts. This ensures reliable signal and power transmission.

Environmental Protection

The SEAM-40-02.0-S-08-2-A-K-TR connector has a UL 94-HB flame rating, indicating it is resistant to burning and is ideal for use in enclosed, dangerous locations. It also has IP67 protection rating, meaning it is dustproof and waterproof when used in wet or hazardous environment. The connector is also RoHS compliant, which ensures any materials used meet environmental regulations.

Conclusion

The SEAM-40-02.0-S-08-2-A-K-TR connector is an ideal choice for high-speed signal transmission and power distribution applications. Its features including high-density design, high contact density contacts, double set of current contacts, and environmental protection make it an ideal choice for use in a variety of applications where reliable signal and power transmission is required.
