MMS-105-02-S-DV-04 Application Field and Working Principle

Rectangular connectors, also known as headers, receptacles, female sockets, are electrical connectors that can be used for applications such as radio frequency (RF) barriers, power distribution, control systems, and electrical wiring. The use of these connectors varies depending on the application, and many factors such as the type of cable employed, the current rating, and the environmental conditions must be taken into account. The MMS-105-02-S-DV-04 is a type of rectangular connector that has the ability to withstand high current intensity and is built for high-frequency applications. This connector is a miniaturized connector designed to meet the stringent requirements of today’s high-tech electronics and communications systems. It provides two mating slots that contain two rows of 16 pins each, accommodating for a total of 32 contacts of a 2.54 mm square spacing. It has an operating temperature range of -55°C to +105°C and offers integral shielding to protect against electromagnetic interference (EMI). The MMS-105-02-S-DV-04 also features power and signal dual-slot contact design, a high-frequency repetitive connection, a self-aligning feature, and a dense connection. The power contacts are plated with tin over copper and the signal contacts are plated with gold over nickel. In addition, the contact portions are soldered into the corresponding PCB pads using a soldering iron.The working principle of the MMS-105-02-S-DV-04 is relatively straightforward. Upon plugging in the mating connectors, heat is produced due to the electrical current conduction which causes thermal expansion of the gold-plated contact springs. These contact springs, as a result, push against a force that is magnified due to the pressure mounting, creating a contact force between the contact surfaces of both connectors. The presence of gold in the contact surfaces prevented corrosion due to environmental exposure. This keeps contacts clean and results in a good electrical connection throughout the life of the connector. The MMS-105-02-S-DV-04 is suitable for a variety of applications including data communications, power line routing, control systems, automotive, and avionics. The miniaturized design of the connector makes it an ideal choice for various space-saving applications, while the high-frequency characteristics make it an ideal choice for high reliability applications. Additionally, the self-aligning feature of the connector ensures secure contact mating even when the mating connectors are misaligned. In conclusion, the MMS-105-02-S-DV-04 is a miniaturized rectangular connector specially designed for high-frequency applications in high-reliability environments. It features two rows of 16 pins each, accommodates for a total of 32 contacts, has an operating temperature range of -55°C to +105°C and provides integral shielding against EMI. Furthermore, it has a power/signal dual-slot contact design and a self-aligning feature to ensure secure contact mating even when the mating connectors are misaligned. The MMS-105-02-S-DV-04 is suitable for a variety of applications including data communications, power line routing, control systems, automotive, and avionics.
