Card Edge Connectors are specialized electrical connectors used to facilitate the connection between circuit boards and complementary external devices. The 3448-55 series is a mid-size edge connector designed for medium-density applications. It accommodates up to 55 pins and is suitable for boards with up to 7.4 mm thickness. With its split contact design and strain-relief shield, the 3448-55 offers excellent interconnection reliability in a variety of industrial, residential, and commercial applications.

3448-55 is designed to be a multi-purpose connector system with several applications. It is commonly used in communication, industrial automation, and server/storage equipment. The connector supports a wide variety of signals, including analog and digital signals, including power, Ethernet, and Serial. In addition, the 3448-55’s shielded design helps reduce the risk of electrical noise and crosstalk, making it an ideal choice for high-speed data transmission.

The 3448-55 offers improved performance over standard unshielded card edge connectors, thanks to its well-designed and reliable structural components. The connector\'s header is made of durable stainless steel, and the contact receptacle is made from a proprietary plastic material that is highly resistant to chemicals, heat, and vibration. This robust construction ensures that the 3448-55 can stand up to extended use in challenging environments.

Working Principle: The 3448-55 edge connector uses a set of beveled contact points that mate on both sides of the board. The contact points are arranged in staggered rows, which helps reduce the risk of crosstalk. The metal shield is formed around each row of contacts to protect them from the risks of electromagnetic interference (EMI) and radio frequency interference (RFI). When the card is inserted into the edge connector, the shield is pressed down over the contacts, establishing an electrical connection between the contacts.

The 3448-55 connector is designed to withstand the rigors of continuous use. It has an IP67 rating, making it dustproof and water-resistant. Furthermore, it is rated for up to 10A current and 3kV contact resistance to ensure reliable performance. The contact resistance is further improved through the use of gold-plated contact points.

The 3448-55 is also designed to stand up to extreme temperatures. It has an operating temperature range of -20° C to +85° C, allowing it to be used in a variety of applications, including outdoor and automotive systems. The connector is also RoHS (Restriction of Hazardous Substances) compliant, making it an environmentally friendly choice for engineers designing new products.

The 3448-55 edge connector is a reliable and versatile product for designers who require high performance and reliable data transmission. With its high-speed, low-noise capabilities and its robust construction, the 3448-55 is well-suited to a variety of applications in the industrial, residential, and commercial industries. This versatile edge connector is an excellent choice for engineers who need a reliable and cost-effective solution for their next design.
