Terminal Blocks - Barrier Blocks0387203920 application field and working principle Terminal blocks, also known as barrier blocks, are electrical components used in modern industrial automation systems to securely connect two sections of a circuit. They are designed to ensure a secure connection between the two sections while allowing for easy removal and installation of the components. A typical terminal block will contain multiple terminals, each of which is capable of connecting one wire to the next. The terminals are usually mounted onto a base and held in place with a screw or nuts and bolts. The connections between the terminals can be made using either mechanical or electrical methods.Terminal blocks are commonly used in a wide variety of industries and applications, such as: connecting motors and sensors, splicing power and control wires together, providing power to end-devices, and carrying out analogue or digital bus systems. They are an invaluable asset in industrial automation systems and can greatly reduce the cost of wiring, labor, and potential problems with incompatible connections.In terms of their working principle, terminal blocks have a simple design and operation. They use a small amount of electricity to create a current passing through a small embedded wire or other conductor such as a spring or semiconductor. The current then creates an electro-magnetic field which is generated by the terminal block. This electro-magnetic field is used as a connection point between the two sections of a circuit. This connection point is much stronger than that of other connection points and prevents problems such as resistance and heat. The operation of a terminal block is simple and does not require complex knowledge of electronics or physics. There are generally two types of termination blocks; soldered and crimped. Solder connections are simply those where the connection is made with the use of a soldering iron. Crimp terminals on the other hand, use a terminal block with curved bars or blades which are crimped around a wire to create a secure connection. Both methods are reliable and offer a secure, reliable connection between two parts of a circuit, however, soldered connections are generally considered superior due to their reliability and strength.Terminal blocks have a wide variety of uses in modern industry, from providing a secure connection between two sections of a circuit to providing power to end-devices, and carrying out analogue or digital bus systems. They are an invaluable asset in industrial automation systems and can greatly reduce the cost of wiring, labor, and potential problems with incompatible connections. The simplicity of their design and operation ensures that they are an ideal choice for industrial applications where reliability and strength are of paramount importance.
