Terminal blocks, also known as barrier blocks, are electrical connection devices which allow for the efficient attachment of a conductor to a terminal. A20420707CAR50 is a type of terminal block, a connector specifically designed for the field of industrial automation and machine control systems. This article will provide an overview of its application field and working principle.

The Application Field of A20420707CAR50

A20420707CAR50 terminal blocks, also referred to as double-level terminals blocks, are most commonly used in control panels and factory automation systems because they offer superior performance and a wide range of functions such as reliable, interference-free connections, insulation, and protection.

This terminal block is specifically designed to facilitate the connection of cabled components to controllers such as motor drives, servos, programmable logic controllers (PLCs), and PLC-related devices. The combination of a terminal block, jumper, and termination strip enables a quick, reliable connection making the process of connecting/disconnecting components time-saving. The terminal can also be mounted in a variety of ways such as on rails, frames, and panels.

A20420707CAR50 terminal blocks are also ideal for use in the military/aerospace, telecom, power, and instrumentation industries due to their ability to withstand high power loads and field vibrations. They can also be used in hazardous locations and inherently hazardous environments.

The Working Principle of A20420707CAR50

A20420707CAR50 terminal blocks use barriers to provide safety and ensure reliable connections between terminals and wires. The barriers create an electrical separation between power and control circuits thus preventing the incorrect connection of wiring. The block is typically made up of a base, terminal or connection strip, housing, and a lever or locking mechanism.

To begin the connection process, a jumper or conductor is inserted into the terminal or connection strip. The electrical connection is only optimized when the lever or locking mechanism is engaged firmly. When the lever is pressed down, the conducting part of the terminal block is short-circuited to the base plate. This action makes the connection secure and complete allowing power to flow to the connected component. The locking mechanism also helps to prevent accidental disconnections or voltage drop if there is any vibration in the system.

The advantage of using a double-level terminal block like the A20420707CAR50 is that it can accommodate two separate connections. This allows for multiple components to be connected to one terminal without having to use multiple connectors. This is especially useful in control panels and machine control systems where multiple components have to communicate.

Conclusion

The A20420707CAR50 double-level terminal block is an efficient, reliable, and versatile connection device for use in the field of industrial automation and machine control systems. It is designed to provide safety and ensure secure connections between terminals and wires. This terminal block can also be used in hazardous locations and inherently hazardous environments. With the double-level design, A20420707CAR50 makes it easy to connect multiple components in control panels or machine control systems.
