Rectangular Connectors - Headers, Male Pins are used for the purpose of connecting one device to another. Used in computer applications, for example, as form factors for linking memory boards, motherboards, expansion cards, and audio components. They also find application in laboratories, industrial machines and vacuum systems. The MTMM-120-03-G-D-138 is one such connector that is made from top-grade materials for increased longevity and reliable performance. This article will look at the application field and the working principle of the MTMM-120-03-G-D-138 rectangular connector.

Application Field

The MTMM-120-03-G-D-138 is a versatile connector suitable for a range of markets and applications. These include communication equipment, consumer electronics, medical equipment, computer peripherals, industrial factory automation, and more. It is an advanced connector featuring a three-row female header with an 18-pin layout of 2mm pitch and an unshrouded design. It is made from superior quality materials such as tin-plated brass and gold-plated contacts which ensure low resistance and long-term durability.

The high-performance MTMM-120-03-G-D-138 connector is designed to meet industry standards and exceeds the highest electrical requirements. It comes with an inherent current-carrying capacity of 1.3A and a tolerable voltage rating of 220V AC/DC. It also offers excellent insulation properties, making it ideal for high-density single-board computer applications in laboratories, industrial machines, and vacuum systems.

Working Principle

The MTMM-120-03-G-D-138 connector enables a reliable mating of two devices or circuits. Its 18-pin layout consisting of two rows of pin headers and one row of female headers makes it possible to mate two separate circuits. A male header is inserted into the female header and its electrical contacts engage the female header’s contacts, completing the electrical circuit. This provides an electrical pathway between the two circuits, enabling them to exchange signals and power.

In terms of construction, the connector features a polarized design, allowing only one way of mating. This prevents a wrong connection in which the circuits end up with different polarity voltages. It also features a crimp design which minimizes the potential for incorrect wiring. Its metal parts are gold-plated to ensure a reliable contact and a low electrical resistance.

Conclusion

The MTMM-120-03-G-D-138 is a high-quality, rugged rectangular connector from the Rectangular Connectors - Headers, Male Pins family. It is designed for reliable mating of two circuits as it comes with a polarized design and a 3-row layout with 18-pin headers. The superior materials used for construction ensure its longevity and reliable electrical performance. It finds application in communication equipment, consumer electronics, medical equipment, as well as computer peripherals and industrial factory automation.
