The SEAM-20-01-L-08-1-RA-TR is a rectangular connector which falls within the array, edge type, mezzanine (board to board) category. It provides a reliable connection between two printed circuit boards, and is mainly applied to connect high-speed signals, and/or power in complex space-constrained electronic systems.

The SEAM-20-01-L-08-1-RA-TR is composed of a plug (or header) that is connected to a receptacle (or socket). The plug has four rows of 4 mm pitch contacts, while the receptacle features two signal straps and one shield.

The contacts on the connectors are configured in a 2 x 20 layout. The plug has an assembled length of 43 mm, while the receptacle has an assembly length of 55 mm. The connectors feature a 2.54 mm metallic shell height, and a contact surface area of 10.27 square mm per contact. The contacts are plated with gold (30 μin minimum) for improved electrical performance and better corrosion resistance.

The SEAM-20-01-L-08-1-RA-TR features an integral keying system that prevents misalignment during mating. This makes it suitable for applications where polarization and robust connections are needed.

The SEAM-20-01-L-08-1-RA-TR is designed to meet a number of performance and reliability requirements including quality assurance, temperature cycling profile (TAL), and insertion test (MIT). It also complies with electromagnetic compatibility (EMC), electromagnetic interference (EMI) and optical safety requirements.

The SEAM-20-01-L-08-1-RA-TR connector uses a locking mechanism with bridges which ensures secure locking of the plug and receptacle for improved reliability. It is designed for reflow or wave soldering processes, and meets or exceeds all of the requirements for printed circuit boards assembly processes.

The working principle of the SEAM-20-01-L-08-1-RA-TR is simple yet effective. First, the contacts on the plug and receptacle are aligned and aligned properly by using the keys. Then, when the plug and receptacle are mated together, the bridges on the connector lock the two parts securely together. When the plug and receptacle are mated together, the locks immobilize the two parts, while the contacts make the electrical connection between the two boards.

The SEAM-20-01-L-08-1-RA-TR is designed for reliable performance in a variety of demanding applications. It is commonly used for connecting 3U and 4U boards, Ethernet and USB boards, backplanes for telecom and data processing, and many other signal and power connections in space-constrained applications. This connector is rugged, reliable, and offers excellent thermal and environmental performance for long-term, reliable operation.
