Working Principle

The ESQT-128-03-L-D-340 is a family of female sockets designed to provide a reliable connection between two components. The connection is achieved by metal contacts that are inserted into the socket and are engaged with the device’s pin.The contact system is designed to ensure that a high level of mechanical resistance is achieved, allowing the secure locking of the contact in place. The contact is then firmly held in place by a metal spring that connects the contact to the housing.Additionally, the contact system features a self-cleaning process that maintains a clean contact surface. This helps to reduce contact resistance and subsequently eliminates any potential for contact flicker.The connectors also feature a robust mounting system that provides secure attachment to the mounting panel. The mounting is achieved with the help of screw locks that are fastened to the mounting panel. Furthermore, the connectors are also designed to be used with both vertical and horizontal mounting. The connectors are also designed to be compatible with multiple termination types, such as quick-fit and soldering. This provides flexibility to the user.

Conclusion

The ESQT-128-03-L-D-340 connectors are an example of the family of rectangular connectors designed for high-quality, reliable connections. The connectors feature a high quality contact system, a robust locking mechanism, and multiple options for termination and mounting. The connectors are designed for a range of applications in the field of communications and power supply, and they provide a reliable and secure connection between two components.
