Rectangular connectors are ubiquitous in many types of electrical installations. In these installations, headers, male pins, and other types of connectors are used to complete the electrical circuit. One type of rectangular connector often used for these purposes is the LTMM-122-02-F-D-RA.

The LTMM-122-02-F-D-RA is a female, double-row, plug-in pin connector. It features two rows of 12 pins and has an insulation height of 2.00mm. The contact area is copper-treated, and it is rated for contact resistance of 40 milliohms, voltage rating of 250VAC, and current rating of 3A.

In terms of application fields, the LTMM-122-02-F-D-RA can be widely used in industrial automation, controllers, IOs, one/two-way devices, current loop sampling, communication, and other fields. Because of its high temperature resistance and high electrical performance, it is also used in automotive applications, such as engine control systems. It is also often used in laptop computer peripheral devices.

In terms of working principle, LTMM-122-02-F-D-RA uses contact-type soldering method to complete the connection. The electrode surface of the pin is first tin-plated or passivated, aiming to reduce the contact resistance, improve electrical performance, and ensure reliability of the connection. For different working environment, different surface treatments are used, such as oxide passivation, blackening, etc. Under the action of soldering heat, the contact face of the pin will be fused with copper foil of the PCB pad, and that’s how the connection is completed.

Also, the LTMM-122-02-F-D-RA provides a mechanical connection, which holds the whole connection structure together and enhances the connection strength. The pin and the connector have their corresponding hole and groove. When the connector is inserted into the pin, the electrical connection is combined with the mechanical connection, and the electrical connection is formed.

In conclusion, the LTMM-122-02-F-D-RA is a female, double-row, plug-in pin connector, used in various industries. It uses contact-type soldering method to complete the connection, which combines the electrical connection of the pin with the mechanical connection of the connector. With its high temperature resistance and high electrical performance, it is often used in various fields, such as industrial automation and engine control systems.
