Rectangular connectors are one of the most commonly used connection types in various electronic devices. The 172039-1 is a type of rectangular connector that is basically a header with male pins used in the applications of network cables and connectors. This connector type is mechanically and electrically compatible with the mini-posts referred to as MT36 and includes thermoplastic insulator, passivated finish contacts, a coding system and only required crimping tool.

Application and Working Principle

The 172039-1 is widely used in the application of most Ethernet cable assemblies, digital and consumer electronics, mobile device and computer peripherals, telecom equipment, broadcast equipment, networking equipment, automotive and industrial control applications. It is also suitable for a variety of application, such as pin assignment for RS-232/422/485 standard, HDMI connector, micro-USB connector, etc.

The use of 172039-1 for mobile phone data transmission and external interface has become increasingly more prevalent, benefiting from its small size and good signal transmission performance. Its male pins are 8.5mm long and mainly made of copper alloy. The material of pin plating usually is one of the following three types, gold, silver or nickel. The addition of lead ensures good electrical conductivity characteristics and its service life usually reach more than one hundred cycles.

In addition, 172039-1 meets three different environmental standards. For example, its insulation withstands 1500V AC(60S), and its contact resistance is <=50mΩ. The insulation thickness is 1.8mm and the normal operation temperature range is between -45℃ to 105℃.

Furthermore, the 172039-1 connector is easy to install and dismount due to its crimp type. It only requires a crimping tool for the installation. Then, the connector needs to be inserted into the coupled receptor connector. After that, the two parts are able to be pressed together. The user just needs to slightly pull the connector out for the disassembly.

Conclusion

The 172039-1 is one of the most popular rectangular connectors today due to its compact size, good signal transmission performance, long service life, easy installation and dismount. It mainly serves connection applications in computer peripherals, mobile device, network cables, telecom equipment, automotive and industrial control applications. 172039-1 also meets three kinds of environmental standards, including a normal operation temperature range from -45℃ to 105℃, an insulation withstand of 1500V AC(60S) and a contact resistance of no more than 50mΩ.
