Terminal blocks, also known as barrier strips, are electrical components used to connect two or more electrical circuits together. More succinctly, a terminal strip is an assembly of insulated terminal blocks, headers, plugs, and sockets. These components are then commonly mounted to an electronics chassis connected to a power source.

Terminal blocks are primarily used to connect wires in an electrical circuit, and can create a very stable connection - as opposed to soldering. These components are essential in many applications, such as in audio equipment, computers, motor control systems, and more. When properly sized and used, they provide a great electrical connection between two or more wires.

Nowadays, many terminal blocks use a pitch size of 5.08mm, which is commonly referred to as a 0.2-inch pitch. It is a popular choice because of the wide range of pins and connections it can easily facilitate. The terminal blocks also work with multiple wire types; from solid core and flexible strand wires to cables designed to assist in the transportation of the signal. A wide range of insulation type also lines terminal blocks: for instance, PVC or PPE insulation.

Various types of terminal blocks are used in different electrical applications, for instance, headers, plugs, sockets, etc. Headers are the most common type of terminal block and are used to easily connect multiple components to a single electronic system. Conversely, plugs and sockets are used as detachable connectors to quickly expand the system or to easily perform maintenance. They are also usually designed with a locking system that prevents the connection from being unintentionally broken.

Terminal blocks come in many shapes and sizes. They may come with a wide range of current and voltage ratings and have various features such as age rating and UL certification. Many manufacturers offer custom terminal blocks, which allows for further characteristics and size specifications to suit any specific application. For instance, 1289950000 is a terminal block from Hellermann Tyton. It is UL94V-0 flame retardant approved and is used for connecting control cabinet and panel wiring.

Terminal blocks are used in a wide variety of applications, from commercial to DIY projects. Their electrical connections play a crucial role in connecting and powering many electronic systems. And, since they are relatively easy to use and replace, it makes them an attractive choice for both professionals and hobbyists.
