Terminal Blocks - Barrier Blocks

Barrier Blocks ( also known as Terminal Blocks ) are one of the most versatile and customizable electronic components available. They are used to create electrical connections or break electrical power, thus offering a range of benefits in the applications of electrical communications, automotive and industrial control industries. Barrier blocks are designed to provide efficient and reliable electrical connections. Their construction and design vary depending on the application and the type of material used.

Barrier blocks are typically enclosed by a polycarbonate shell or an electrical insulation flexible conduit. Depending on their construction they are available in either single or dual pole varieties. Single pole blocks are frequently used in low voltage and digital applications such as PLCs, sensors and motor control applications. Dual pole blocks are designed for higher voltages, such as 24V or 48V for power applications. They are also used in many automation, instrumentation and audio/video systems.

Barrier Blocks have two main operating principles: They create a physical barrier that prevents an electrical current from passing through, and they provide a reliable connection between two components. The physical barrier is created when the upper layer of the block is stripped off exposing the copper conductor beneath. This then establishes a contact point between the two components, allowing an electrical current to flow between them.

To ensure a reliable connection, Barrier Blocks are designed to maintain a certain pressure on the contact points. This ensures that the connection between the components is secure, and prevents any electrical problems such as arcing, which can occur if the connection is too loose. Pressure can also be adjustable to accommodate different types of materials such as metal, plastic, or rubber.

In addition to creating electrical connections, Barrier Blocks are also used to help protect both the components and the wiring from over-voltage surges and other potentially damaging electric events. The barrier acts as a safety device, preventing electricity from passing through and causing damage.

Barrier Blocks are used in a variety of electrical applications, such as switchgear, motor control systems, lighting, instrumentation, laboratory equipment, and many other industrial and commercial applications. They are available in a variety of sizes, and colors, making them suitable for nearly any application.

These versatile blocks can provide reliable electrical connections as well as serve as a safety device, making them a must-have component in many electrical applications. Whether you are building an industrial control system or an automotive control system, Barrier Blocks are a great choice for providing reliable and secure electrical connections.
