Overview of MDF7-22DP-2.54DSA

The MDF7-22DP-2.54DSA is a double-row dual-row, full duplex (CCO and DCO) rectangular connector with male pins for section 9 in the Maxi separable connectors range, which is part of a series of PCB connectors. The MDF7-22DP-2.54DSA connector works at up to 1A and 25V when in a mated state, making it ideal for use in high-density rectangular interconnection applications that require reliability and space-saving.

Application Fields of MDF7-22DP-2.54DSA

MDF7-22DP-2.54DSA is highly suitable for applications requiring high-speed digital signals, such as mezzanine systems, backplane assemblies, and wired Ethernet cables in networking and telecoms equipment. It is also used in a variety of other industrial applications, including medical diagnostic equipment, automotive diagnostics, and telecommunications equipment. Its high-performance design ensures reliable operation in a range of environmental conditions.

MDF7-22DP-2.54DSA Working Principle

MDF7-22DP-2.54DSA uses a double-row, full duplex design to ensure reliable mating and unmating even in damp or wet conditions. The double-row configuration increases the contact force between the mating connector and headers, which improves the reliability and performance of the connections. It also reduces the potential for misalignment, which is a common problem in connectors with single-row designs.Each contact is soldered onto a common substrate, which contains a series of pins that mate with a corresponding type of connector body. The pins are machined in such a way as to allow for consistent mating with the header. The connector body features group of internal sockets with slots for closely positioning the pins to ensure firm mating. The body also has locking tabs that latch the pins securely into place.The manganese bronze alloy used to manufacture the MDF7-22DP-2.54DSA ensures excellent thermal and electrical contact between the pins and the header. The alloy also provides a degree of corrosion resistance, making it ideal for use in high humidity and other corrosive environments. The contact force between the header and pins is further strengthened by the incorporation of a plastic bar between the pin and the connector body. The bar also keeps the pins securely held in place and prevents the pins from being dislodged during rough handling.

Conclusion

The MDF7-22DP-2.54DSA is a rectangular header connector with dual-row, full duplex design for high-speed digital signals. It offers excellent performance, reliability, and space-saving features for a range of applications, including mezzanine systems, backplane assemblies, and wired Ethernet cables. Its high-performance design utilizes a manganese bronze alloy to ensure excellent thermal and electrical contact and corrosion resistance. It is also fitted with a plastic bar for securely locking the pins and prevents them from being dislodged during handling.
