• Operation temperature: -55 to +105°C

Working Principle

The 64991-S25-4LF connector is a type of male pin header, meaning that it has pins protruding from it for making connections. The connector itself is made up of two parts – the pin header and the insulator. The pin header is made up of the contact pins, which are made of brass and gold plated to provide corrosion resistance. These pins are mounted on the insulator, which is made from high-temperature Polyamide (Nylon). The insulator provides strain relief and electrical insulation between the pins and the surface to which the connector is attached.

The operation of the connector is simple. The contact pins are inserted into the mating connector and a secure connection is established. The connector’s design ensures that a secure connection is maintained even when subjected to vibration and physical strain. The connector’s robust design and gold plated contacts also reduce contact resistance, ensuring reliable connections.

Conclusion

The 64991-S25-4LF connector is a reliable and robust rectangular connector suitable for a wide range of applications. It has a high current and voltage rating and its gold plated contacts reduce contact resistance, providing reliable connections. Its compact size makes it suitable for space-limited applications, while its robust design ensures a secure connection even when subjected to physical strain and vibration.
