Card edge connectors, also known as edge card connectors, are multi-pin connectors that are used to mechanically join an electrical printed circuit board (PCB) to the host system. These connectors are highly versatile and can be used to connect signal and data lines along with providing protection of the board and its components from shock, vibration, dust, and other environmental elements. The 5147439-2 model is a two-row, vertical, SMT (surface mount technology) connector with a 50-mil pitch. It offers a cost-effective, high density solution for card-edge applications and is rated to a maximum operating temperature of 150°C.

Application Field

The 5147439-2 is widely used in telecommunications, data communications, and industrial controllers. It is also used in consumer electronics, including devices such as computers, televisions, stereos, and VCRs. The connector provides a robust, reliable, and high speed connection ideal for board-to-board applications, such as those involved in wireless communication systems and Internet of Things (IoT) applications.

Working Principles

The 5147439-2 has gold plated contact pins that mate with a printed circuit board, providing a reliable electrical connection. The pins are arranged in two rows and are designed for a Zero Insertion Force (ZIF) attachment. The ZIF attachment requires minimal effort to insert the connector into the board and the connector can be easily removed by releasing the latches on either side. The connector has a testing tab that can be used to test the connection before it is locked to the board. Once the connector is locked, it is held secure by two spring-loaded latches.

The board-to-board connections provided by the 5147439-2 are rated up to 5 amps and are capable of supporting signal speeds up to 33 Mbps. The connector features an anti-vibration system that eliminates the need for delicate component placement. This ensures that the connector will stay securely attached to the board even in harsh environments. Furthermore, the connector is RoHS (Restriction of Hazardous Substances) compliant, making it suitable for many industrial applications.

The 5147439-2 is a versatile and reliable card edge connector that is suitable for a variety of applications. Its durable construction, small footprint, and high signal-carrying capacity make it an ideal choice for board-to-board connections in consumer electronics and industrial applications.
