644486-7

Rectangular Connectors - Headers, Male Pins have found extensive use in recent years. A popular type of Rectangular Connectors - Headers, Male Pins is the 644486-7 connector. It is often used in the field of industrial automation, providing power, data communication and other necessary electrical signals between different devices in the system. This article will discuss the characteristics and working principle of the 644486-7 connector.

Characteristics of 644486-7 Connector

The 644486-7 connector is a type of rectangular multi-pin connector suitable for use in high-density applications. It is the evolution of the traditional rectangular connector, which has been a common choice for many industrial automation applications. The 644486-7 connector features a slim design for high-density applications, allowing more space to be available on the circuit board for other components. Moreover, its 0.4mm pitch contact enables higher connection density and harness flexibility in comparison to previous rectangular connector models. It also features an anti-jamming design, allowing it to avoid signal interference.

The 644486-7 connector is available in both vertical and right angled versions, and comes with both pin and socket kits, allowing for a wide range of connection combinations and configurations. Its reliable latching mechanism ensures a secure connection between two different components, while its reinforced shell design provides excellent protection against dust and other form of environmental contamination. The 644486-7 connector meets the IEC 61076-3-106 standard and is tested to perform at 500 mating/unmating cycles without degradation.

Working Principle of 644486-7 Connector

The 644486-7 connector utilizes a metal contact system that uses spring pin contacts for power and signal transmission. The pins, which are made of sturdy phosphor bronze, mate securely with the corresponding pads in the socket. The pin contacts feature a standard 0.4mm flat pitch and use a gold plated surface for enhanced performance and reliability. They’re also designed to avoid short-circuiting, as they are universally insulated at the end.

When two 644486-7 connectors come into contact, the pins and sockets make an electrical connection. The pins are inserted into the socket and the male and female housings are engaged. This enables power and/or signals to travel between the two components. During operation, the contacts are maintained in an open position by the built-in retention shields. The isolation slots in the male housing ensure that the signal lines for the contacts of the same connector are kept apart, preventing interference between them.

Once the two connectors are disconnected, the spring pins will reset due to the Spring Pin Mechanism System, thus ensuring easy disconnection and re-connecting when necessary. This system also adds to the 644486-7 connector’s robustness and provides excellent performance in rugged applications.

Conclusion

The 644486-7 connector is a popular type of rectangular multi-pin connector suitable for use in high-density applications. Its slim, robust design and reliable latching mechanism ensure a secure connection between components, while its reinforced shell design provides excellent protection against dust and other form of environmental contamination. The 644486-7 connector’s metal contact system uses spring pin contacts for power and signal transmission, while its Spring Pin Mechanism System provides easy disconnection and re-connection. Thus, the 644486-7 connector is an invaluable tool for connecting essential components in industrial automation applications.
