Rectangular Connectors are among the most popular and versatile connectors, and are widely used all around the world. Among this huge variety, DMC-M 20-22 SC Aplication Field and Working Principle are well sought by professionals.

What is DMC-M 20-22 SC? DMC-M 20-22 SC is a rectangular connector, and a variant of standard dual-row header plug design. It has a simple but effective structure: two rows of 12 pins each, connected in parallel with the mating connector. The contact area is designed in a better way, with easy insertion and orientation. With higher power rating and electrical performance, this plug type is especially suitable for high-current power connection.

The materials which are commonly used in DMC-M 20-22 SC connectors are copper and the inserted solid material. The contact surfaces are plated with gold-palladium alloy for better electrical conductivity and resistance performance. This kind of surface-plated connector works better in different working environment.

Regarding the application of DMC-M 20-22 SC, this kind of plug headers is most suitable for the application of instrument connecting, PCB connecting, power supply and control system connecting. It is the preferred choice for any power-related devices, such as HVAC and other industrial appliances。

The working principle of DMC-M 20-22 SC is based on the two rows of contact tails for electrical isolation. The two rows are connected in parallel, and they act as two separated contact grids. When the mating plug is inserted, the contact tails move upward, and the number and alignment of each tail correspond to its mating surface. Once connected, the contact tail is secured with the force of its own spring support, thus providing a solid connection and current transmission.

Therefore, this kind of DMC-M 20-22 SC connection has the following characteristics:

• Lower electrical contact resistance;
• High current carrying capacity and short-circuit protection;
• Independent tail contact, good reliability, high security;
• Mating devices design is verified with different conditions.

In conclusion, DMC-M 20-22 SC rectangular connectors can provide a secure and reliable power device connection, and its application field and working principle are well known by professionals. With its reliable electrical performance and better contact surfaces, it is the perfect choice for instrument connecting, PCB connecting, power supply and control system connecting.
