SEAM-40-07.0-L-08-2-A-K-TR

The SEAM-40-07.0-L-08-2-A-K-TR Rectangular Connector is an Edge Type Array designed for Board-to-Board applications. It is part of a larger product family from Amphenol, the leading global manufacturer of interconnect systems.

The two components of this connector, the Plug and the Receptacle, are designed to provide high-speed signals and power through both vertical and horizontal board stacks. The 40 positions are all arranged in double rows, with 7mm of pitch between them. These positions are further divided into 2A and 2K subtypes (2 positions A, and 2 positions K) for greater versatility, and they are all configured in-line. All 40 positions can be used to provide signal and/or power, with up to 12A on each 2A pair, and up to 3A on each 2K pair. Each position can accept up to a 20 AWG stranded or up to 18 AWG solid wire. The 2A positions also feature terminals for auxiliary grounds.

The SEAM-40-07.0-L-08-2-A-K-TR connector consists of a Plug and Receptacle with matching riser heights and a consistent cable entry angle across all positions. The connector housing is made of high temperature and high strength Polyetherimide (PEI), and the contact area is Gold-plated Copper with a Tin-plated solder cup. Both the Plug and the Receptacle feature integrated guides for a secure mated contact, and the Receptacle also houses a locking sleeve with two robust arms. This locking sleeve adds friction to the connection and holds the plug firmly in place. It also maintains proper stacking and prevents inadvertent unmating.

The SEAM-40-07.0-L-08-2-A-K-TR is an Edge Type Array, meaning it can provide highly efficient connections between several boards without occupying too much valuable space inside the product enclosure. It offers the performance and reliability of traditional Edge-Mate connectors, with the advantages of a compact form factor. This makes it ideal for Mezzanine (Board-to-Board) applications where design space, cost, and performance are critical factors.

In summary, the SEAM-40-07.0-L-08-2-A-K-TR Rectangular Connector is an excellent choice for Mezzanine Board-to-Board applications that require high-speed traces, power, and ground, in a compact form factor. Its reliable locking mechanism ensures a strong, secure connection, while its innovative design allows it to occupy less space than a traditional Edge-Mate connector. It is part of a larger product line from Amphenol, a leader in interconnect systems.
