Working Principle

The 644740-4 is a female receptacle connector, and as such acts as the point of connection for male cable ends. When connected, the pin contacts aligned with the grooves on the insert are mated together and held in place with the use of a locking clip. The locking clip is used to ensure a secure connection, and to prevent unintentional disconnection.

The 644740-4 also has an integrated ground contact, which adds increased protection to the connection. The ground contact is a third contact on the header, which is connected to the shell of the connector. This allows the connector to be grounded, preventing any potential EMI (electromagnetic interference).

Conclusion

The 644740-4 is a versatile connector, offering a unique combination of features and benefits in an easy-to-use package. It is suitable for a variety of applications, from industrial machinery and control systems to computer and peripherals. Its reverse polarity design, compact size, and integrated ground contact make it a reliable, durable, and cost-effective choice.
