Terminal Blocks - Barrier Blocks

0386907828 Application Field and Working Principle

Terminal blocks, also known as barrier blocks, are one of the most common types of terminal used in the industrial automation field. They are used to connect wires to electronics devices and provide a secure and reliable connection. Barrier blocks are designed with two components: a terminal block and a barrier strip.

The terminal block is the component that is mounted on a circuit board. It is a simple device that consists of two metal pins or blades that line up with the terminals of a device. This allows for an electrical connection to be easily made. The terminal pin or blade is usually insulated with a plastic or rubber covering to protect it from short circuits. The pin or blade can then be connected to a wiring harness or a printed circuit board via screw terminals.

The barrier strip is the part that is connected to the terminals on the device. It consists of a series of parallel wires or strips of metal. These strips form a barrier between the terminal pins. This barrier prevents short circuits from occurring due to stray or transposed wires. It also helps reduce the amount of noise generated by the device, as it creates an electrical barrier to prevent interference from external noise.

Terminal blocks are commonly used in the industrial automation field to connect electronics devices to controllers, PLCs, and other components. They are available in both vertical and horizontal configurations. They are typically available in various sizes to accommodate different wire diameters and pin lengths. They are also available in a variety of colors to match the color of the device they are connecting to.

Terminal blocks are easy to install and use. To install a terminal block, first the terminal pins are attached to the device. Then the terminal pins are connected to the barrier strip. The barrier strip is then secured to the device with screws. This ensures a secure connection and prevents it from being affected by external noise.

Terminal blocks are used in many applications such as automotive, robotics, communication systems, process control, and instrumentation. They are also widely used in medical, aerospace, and military applications. They provide a reliable and secure connection for various types of electronics devices.
