B2B-PH-SM3-TB Connectors, Interconnects

The B2B-PH-SM3-TB series of rectangular connectors are head soldering type, male pin header connectors. With high retention and reliable connection, they are very widely used in a great many applications such as industrial automation and avionics.

In their construction, these connectors feature an insulator, mounting plate, terminal and winding presser. Generally speaking, the insulator is made from natural nylon (PA6T). The terminal is typically brass in material. Depending on the configuration, the mounting plate can be either made from brass or steel. And the winding presser is generally steel. In addition, the contact terminal has a very precise tolerance for confirming to IEC10250, and there are special types of stamping parts or machining parts included in the selection of parts available. And as for the external shape of the connector, it is generally trapezoid, uniform diameter and various construction options are available for customers.

For the working principle, the B2B-PH-SM3-TB series are quite simple. They essentially consist of two pieces of metal that are interconnected with a metal pin inserted through the connectors and into contact. The connection is held together by the compression of the metal parts by the pin, ensuring its reliable connection. Normally, the pin is made from nickel-plated brass or gold-plated brass. The contact surface is gold, silver, or tin plated, ensuring it has good contact and reducing its signal transmission resistance. The connection itself is fully insulated and has good high temperature resistance.

Generally speaking, the B2B-PH-SM3-TB series of rectangular connectors are very widely applicable and can be found in many industrial areas such as automobile electronics, industrial automation, and avionics. Their reliable connection and good heat resistance make them very suitable for applications that need to pass high current electrically.
