Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board)

The SEAM-25-03.5-S-04-1-A-K-TR connector is a mezzanine ("board to board") type of connector within the rectangular connectors array family. Its purpose is to connect two printed circuit boards along their sides by passing signals and power through electrical contacts. It is a complete connector system in any application, consisting of two interposers and a complete set of contact assemblies.

Application Field

The SEAM-25-03.5-S-04-1-A-K-TR connector is primarily used in applications where space is at a premium, such as satellite and space shuttle components or applications that involve military-style modular design. It is often used in the telecommunications industry, computer and peripheral technologies, audio/visual, automotive, consumer electronics, instrumentation, medical, and other industrial markets.

The connector is also suited for applications such as data communications systems, networking, industrial control systems, testing and measurement systems, and more.

Working Principle

The SEAM-25-03.5-S-04-1-A-K-TR connector consists of two parts: an interposer and contact assembly. The contact assembly is composed of an array of springs that provide electrical connectivity between the two parts, while the interposer allows for a surface-mount application. After soldering, the spring contacts are compressed against the board and provide the electrical connection between the two parts.

The interposer also provides mechanical stability by mating with the contact assembly. This ensures that the contact assembly is correctly aligned with the printed circuit board. Once the contact assembly and interposer are mated, the overall assembly has high vibration and shock resistance.

The contact assembly is a robust, metal spring that ensures consistent electrical contact force, high durability, and superior performance in demanding environments and applications. The contacts are designed with plated metal or gold flash to ensure reliable and consistent electrical performance.

The SEAM-25-03.5-S-04-1-A-K-TR connector also utilizes a locking mechanism to ensure that the mated parts are secured together. This ensures that the mating parts are properly aligned and stay in place, preventing potential damage or dislodging. The locking mechanism is also designed to prevent inadvertent unlocking or separation of the mated parts.

The SEAM-25-03.5-S-04-1-A-K-TR connector has an operating temperature range of -55°C to +125°C and can withstand humidity and corrosive environments. The contact assembly and interposer are designed for optimal performance and reliable operation in these challenging conditions.

Conclusion

The SEAM-25-03.5-S-04-1-A-K-TR connector is a versatile mezzanine board-to-board connector system for space-critical applications. It is designed with a reliable locking mechanism, high vibration and shock resistance, and robust metal spring contacts for electrical performance. In addition, the connector is rated to operate in extreme temperatures and humid environments. This makes it ideal for a range of applications, such as telecommunications, computers, consumer electronics, instrumentation, automotive, and more.
