4-644627-7

Rectangular connectors, or headers, are specialized multiple-pin electrical connectors commonly used for connecting several electrical components together. In this article, we will discuss the 4-644627-7 application field and working principle.

Application

4-644627-7 connectors are usually used in high output voltage or current applications such as for computer hard disk or power supply data cables, as well as for electric motor connections. High-density connectors are perfect for applications where a large number of connections are needed, as they are small, have a low profile, are inexpensive, and can withstand relatively high temperatures. They are also commonly used in industrial control panels and in the automotive sector for connecting high-current loads like motors, pumps, and actuators.

Working Principle

4-644627-7 connectors feature positive polarisation and a special design which ensures the proper alignment of all contact pins. This helps to ensure a reliable connection and minimise the risk of arcing and short circuits. The contacts are all connected to a single common ground contact, and the pins have a smooth, shock-resistant finish to cope with higher voltage currents. There are also specialised 4-644627-7 connectors designed for higher output currents of up to 70A.

Conclusion

The 4-644627-7 connector is a versatile electrical connector intended for use in high-voltage applications. It features a positive polarisation design which ensures proper pin alignment and eliminates the possibility of arcing and short circuits. It is also used in industrial control panels and the automotive sector, and is available with amperages of up to 70A.
