INTE-AUTO’s circular push pull interface and housing make it easy to connect and disconnect the device. The simple system allows the cable to seamlessly send signal, power, and current. The connector has a brass outshell implanted in the insulation material to help maintain alignment.

The connector has low-voltage contact and is tough, rigid, and versatile. It is well-suited for application in any industry– be it medicine, energy, communications, broadcasting, or others. The circular connector works equally well whether in a damp or dry environment.

When you need to transfer data, current, or signals between two devices, you must need a medium like a wire and a connector that should connect these two devices.

The push pull circular connectors have two external parts called plug and receptacle that allow your data to transfer between the two devices.

The receptacle is connected with the device, and the plug is connected with the cable that is connecting the two devices to make a closed data transferring path.

So the main use of push pull circular connectors is to transfer data, current, or signals between any two electronic devices.

They are efficiently used in defense and security, instrumentation, medical fields, electronics, broadcast, communication systems, aerospace, industries, transportation, and robotics.

You don’t have to suffer energy, data, power, or signal loss. The circular connector design push pull self-locking circular mechanism is reliable and straightforward.

These circular connectors are cost-effective also. After it was designed by the famous brand in the 1950s, it is now almost used in every industry due to its versatility. There’s no sector where the push-pull circular connector isn’t workable.

It allows simple operations, and one has almost nothing to worry about. You can install it once and then use it for long periods. It is easy to maintain and use. The circular connector puts an end to the difficult user manuals as it is directly operatable.

Its design makes it suitable for usage as a fast push-pull self-latching connectivity solution. It creates connectivity quickly for you while being robust, sturdy, and durable. Circular connectors are easy to handle and are space-saving as well. It maintains a streamlined shape, so the aesthetics of the device aren’t affected.

They are designed to have the most lifespan at least 6000 times, so you don’t need to replace them now and then. Despite using it for years, their connectivity resistance remains the same.

The circular connectors can be used in rugged, harsh, challenging conditions. It is modified to be tough and rigid. You would not have to worry about changing your circular connectors more often.
