Rectangular Connectors - Headers, Male Pins

Rectangular connectors are an important class of electrical connectors that are used in electronics, communications, and industrial automation systems. They provide a secure connection between two components while allowing for easy removal and replacement of the connection if necessary. The MTMM-125-09-S-D-370 rectangular connector is a high-performance type of this product family, designed for reliable, long-term operations in load-bearing applications.

Overview of MTMM-125-09-S-D-370 Properties

The MTMM-125-09-S-D-370 rectangular connector is a two-piece connector consisting of a male header and a female pin. It is both functionally and mechanically equivalent to an SMT version of the SN connector, but is engineered specifically for reliable performance in front-panel mounting applications. The product features low insertion and extraction forces, allowing it to be easily plugged and unplugged without damaging the connector, and it has an extremely durable polyamide housing that is resistant to common environmental conditions. The MTMM-125-09-S-D-370 is intended to be used with metal or plastic paneling, and it boasts a contact resistance of <25mΩ, a contact voltage rating of >V, and a current rating of up to 5A.

Dimensions and Interconnectivity

The MTMM-125-09-S-D-370 connector is available in four different plating options: gold, nickel, tin, and gold/silver. It also boasts a low contact mating force of <50N and a minimum spacing of 1.27-2.7 mm between the connector’s male and female contacts. It has a mating depth of 12.5mm, an operating temperature range of -55 to +85°C, and a maximum mating cycles of 750. Additionally, the MTMM-125-09-S-D-370 is designed with a variety of integrated features, such as insulation displacement connection (IDC) technology, polarization, and position alignment features.

Application Fields and Working Principle

The MTMM-125-09-S-D-370 connector is ideal for a variety of industrial automation and communications applications, such as factory automation systems, HVAC systems, data networks, and robotics. It can also be used in medical device, military, and automotive applications. The connector\'s high contact resistance and superior contact quality ensures reliable communication between components, even under extreme conditions. Additionally, its low insertion and extraction forces, as well as its polarized and position alignment features, ensure that it will remain securely connected even in densely-packed installations.

The MTMM-125-09-S-D-370 connector works on the principle of a male header and a female pin, which work together to form a secure connection between two components. The male header has two rows of male pins, which are inserted into the female pin contacts. The female pin contacts are connected to the circuitry, and the header is secured in place by a plastic locking mechanism. The contact resistance and high quality contact connection created by the mating of the male pins and female pins ensures reliable performance even in challenging environments.

Conclusion

The MTMM-125-09-S-D-370 rectangular connector is a high-performance two-piece connector designed for secure and reliable operations in various industrial automation, data network, and communications applications. It has a low insertion and extraction force, a high contact resistance, and superior contact quality, and it is resistant to common environmental elements. Additionally, its small size and integrated features, such as IDC technology and position alignment features, make it the ideal choice for densely-packed installations.
