Overload Connectors Overview:
Also known as heavy-duty sockets, widely used in construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives and petrochemical electrical and other electrical and signal connection equipment.
Pre-installation, pre-installation of large and complex circuits, can greatly improve equipment installation efficiency and reduce wiring error rate.
The connector is convenient and efficient to realize the modular structure of each function module block of the equipment, so that the equipment can be transported, installed, maintained and maintained conveniently and safely. Connectors, in the field of transmission and distribution applications widely.
Heavy-duty connectors provide highly integrated connectivity, and a rich combination of methods maximizes the efficient utilization of equipment space.
The high degree of protection provided by heavy-duty connectors (IP65, IP68) is unparalleled in the harsh environment of the equipment connection system. In the dust, rain, cold, snow, oil and other harsh environments to provide effective protection. Heavy-duty connector in the structural design, material use of the international advanced nature of the connector makes the electrical performance outstanding. The reliability of the electrical connection system can not be achieved by conventional connection methods.


Heavy-duty connectors are of industrial importance:

The new interface is generally considered "industrial connector", its application is not limited to the manufacturing sector. The connectors are designed to withstand the harshest industrial environments. Traditional connection devices provide years of service assurance in a typical office environment. However, exposing the same copper or fiber optic connector to extreme conditions degrades performance and reliability, and end users pay high maintenance costs to troubleshoot and replace parts. A new connector designed specifically to create a rugged Ethernet connection in harsh environments, more resilient, stronger, and more resilient than previous connectors.
