Background

The 54102-0408 connector is a high-speed rectangular connector of the Arrays, Edge Type, Mezzanine (Board to Board) variety. These connectors have pins (or sockets) embedded into their rectangular frame, and feature a high speed differential signals as well as no power contacts. The 54102-0408 connector has standard 4mm pin spacing and allows for a more robust connection than its shrouded counterparts. This connector, from the brand Amphenol, is particularly useful for harsh environment applications, providing a reliable connection between boards separated by a thick housing or between boards in contact with other components. Its excellent durability against corrosion, moisture, shock, and vibration makes this connector ideal for applications where fast transmission speed and extreme reliability is required.

The 54102-0408 connector is designed for high speed signal transmission and provides excellent performance in applications with strict environmental conditions and demanding requirements. These include applications in the aerospace, automotive, military, instrumentation, medical, and telecommunications industries.Amphenol\'s 54102-0408 connectors are often used in high-density computing architectures, such as storage area networks, enterprise servers and data centers. In addition, this connector is well-suited for applications involving consumer and embedded devices as well as rugged mobile equipment.The 54102-0408 connector is also suitable for applications where reliable connection is necessary between two via boards connected with vertical or horizontal arrangement. This connector greatly simplifies board routing with its compact design, and its minimal pin count allows for a high-density solution.

Working Principle

The 54102-0408 is a two-piece board-mount connector that features press-fit pins or sockets. It is capable of transmitting high-speed differential signals between two boards without the need for additional cables, thus providing a reliable connection between two boards.The 54102-0408 utilizes two pairs of specialized contacts that mate with rectangular cavities on both the plug and socket. These contacts include actuating fingers, which provide a spring force that maintains the contact force after connection. The contact cavities in the plug and socket also include positive features to guide the pins and/or sockets into place, ensuring an optimal connection.The 54102-0408 is available in blind-mating versions with mating headers, as well as through-hole versions with a socket on the top side and a rectangular plug on the bottom side. This connector also has snap-in terminals that offer secure contact and eliminate the need for shield wires.This connector is RoHS compliant, and has an improved range of mating heights of up to 4.45mm. It has a current rating of 4A per contact, with a maximum voltage of 200V AC and 500V DC. In addition, this connector has an insulation resistance of 5000M ohms, ensuring the reliability and performance required for demanding applications.

Conclusion

The 54102-0408 connector is a highly reliable and high-performance connector that has excellent durability against harsh environmental conditions. It is ideal for applications requiring a reliable connection between boards, and its compact size and minimal pin count make it a high-density solution for a variety of industrial and consumer applications. This connector is capable of providing a reliable connection between boards, and is designed for the most demanding applications.
