DF40HC(3.5)-50DS-0.4V(70) – Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

DF40HC(3.5)-50DS-0.4V(70) is a type of rectangular connector which falls under the category of arrays, edge type, mezzanine (board to board) connectors. It is a product of Hirose Electric, a renowned electronics and components manufacturer. This particular model has a 3.5mm pitch, 50-terminal count and is rated for 70Vrms (voltage rating) at 0.4A (current rating).

Application

DF40HC(3.5)-50DS-0.4V(70) is widely used in medical equipment, smart home appliances and industrial machinery, mainly due to its excellent reliability and robustness. It is best suited for various high-speed data placing applications such as USB3.1, PCIe and HDMI 1.3. This model features a special high-efficiency array design which makes it suitable for high density transition board designs.

Working Principle

DF40HC(3.5)-50DS-0.4V(70) works on the principle of board to board connection. It has two opposing mating surfaces, each having a set of male and female contact pins. The connectors have a two-dimensional interface pitch capacity which allows them to mate seamlessly without the need for any additional adjustments.The connector has an arrayed design which allows for easier soldering. This ensures that all the pins make a good connection with the board, as long as it is correctly soldered. The male and female contacts are precisely constructed, with a small gap between them, so that electrical connection is securely maintained and a constant flow of electricity is permitted.The connector also features a self-retaining attachment. This feature allows for a secure and reliable connection between the two mating surfaces. At the same time, it prevents the contact pins from being pulled out and safeguarding the connection in cases where the plug is prone to external vibrations. This ensures the reliability of the connection even in cases of excessive movement.

Conclusion

DF40HC(3.5)-50DS-0.4V(70) is an excellent choice for board to board connections, as it is robust, reliable, and easy to install and use. It is ideal for applications that require high-speed data transfer, as it has two-dimensional interface pitch capacity and arrayed design for easier soldering. Its self-retaining attachment also allows for a secure connection that is able to withstand excessive movement, making it a great choice for medical equipment, smart home appliances, and industrial machinery.
