Card Edge Connectors - Accessories

A card edge connector is an electronic accessory designed to interface with either a printed circuit board or a flexible circuit. 3448-54 card edge connectors are one of the most popular solutions used in the industry, known for strong contact retention and high pull-off force. When operating in an active environment, this type of card edge connector provides superior performance and stability. Common application fields for 3448-54 application include the manufacturing of industrial, medical and military circuits.

The 3448-54 utilizes the same physical requirements for contact terminal size as the 3456-72 card edge connector, however it does not require the same length of pin insertion. This type of card edge connector is designed with an interposer or adapter that mounts over the edge contacts. It also has a ribbed mounting style to prevent contact twist and to provide a firm grip to the printed circuit board.

The contact design of the 3448-54 allows for strong, reliable connections with less misalignments. This is due to the positive contact kick-out mechanism, which also helps prevent terminal lift-off and misinsertion. The 3448-54 has a retention force of up to 19 N and a current rating of up to 7.5 A. Furthermore, it also has a gold plating of 4 to 20 microns.

Apart from the features discussed above, 3448-54 card edge connectors also provide shielding and strain relief for greater performance and stability. It is also available in various shapes, sizes, and configurations to meet individual customer requirements. The working principle of the 3448-54 card edge connector is simple and can be understood in three steps. First, the contact terminal is aligned to the printed circuit board which is placed over the contact area. Second, the contact is inserted into the contact area, making sure that it is firmly secured. Finally, a tightening force needs to be applied to ensure a secure connection.

The 3448-54 is a great solution for applications that require a reliable and secure connection. Its zinc die-cast shell and gold-plated terminals make it resistant to corrosion and ensure high stability. With its contact design, high retention force, and wide variety of shapes, sizes and configurations, 3448-54 card edge connectors are ideal for industrial, medical and military circuit applications.
