It can be used to interconnect standard board-to-board interconnections in automotive, industrial, PC/104Plus and PC/104 applications. This backplane connector offers high-density, low profile design, easy assembly, and protection from dust, water, and physical damage. It also offers multiple plating choices of gold, silver, and aluminum to suit customer requirements.

Application Field

The PCN21B-55PC-2W is suitable for both hard metric and standard applications, and can be used for a variety of backplane applications, such as for telecommunications and automotive applications. It is well-suited for high-speed data transmission, high-voltage, industrial applications, Ethernet networks, and military and aerospace applications.

Working Principle

The PCN21B-55PC-2W backplane connector is designed to provide a secure connection between two components. The connector is designed with high mechanical strength and excellent electrical performance characteristics, allowing it to be used for a range of applications. The whole assembly is a two-piece construction with pins and sockets forming the electrical connection between the two components. The pins are inserted into their respective sockets, which are part of a solid sheet located on the back of the connector. The two pieces of the assembly join together with screws or bolts, providing a secure connection. This connector also offers the ability to individually terminate terminals for custom configurations.

The PCN21B-55PC-2W backplane connector is designed for consistent high-level contact endurance and offers good signal integrity. The pins and sockets offer a spring-loaded mechanism to ensure an electrical connection is made before the mechanical connection is set. This also allows connections to be easily overturned for applications in which frequent connection changes are required. The gold plating of the pins ensures low corrosion levels and long-term reliability.
