Terminal Blocks - Headers, Plugs and Sockets

A terminal block, also known as a terminal board or a terminal strip, is a type of electrical connector designed to join two electrical circuits. The terminal block enables circuit connections to be made or broken by disconnecting one or more wires from a device or equipment. Connections can be made quickly and securely without the need to solder. They are used to facilitate electrical connections between wiring harnesses, cables, peripheral devices, and other electrical components. Terminal blocks come in a range of sizes and styles depending on the application.

Angle Blocks

Angle blocks are also known as right-angle terminal blocks and provide secure electrical connections and strain relief for right-angle applications. They have two sides, where one side features a series of pins, while the other has receptacle slots. Angle blocks are commonly used in electrical control panels, relay racks, and other confined spaces.

Panel-Mount Terminal Blocks

Panel-mount terminal blocks are designed for applications where the terminal block is mounted directly onto a panel or enclosure. They have one side with pins for threading of the wires, and another side with receptacle slots. The pins on the panel-mount terminal block are usually arranged in straight or diagonal rows for easy installation. Panel-mount terminal blocks are often available with additional features such as push buttons, indicator lights, and surge protection.

Blade Blocks

Blade blocks are a type of terminal block compatible with most wire gauges and wire types. They have a knife-style blade with multiple pins that are held in place by a top cap. Wires in the same row have identical pitch sizes, which means that various wires can be connected at the same time. The removable top cap also makes for easy installation and removal.

Plug and Socket Blocks

Plug and socket blocks provide an extension interface between two electrical circuits. They consist of two connectors; the plug and the socket. Most plug and socket blocks are compatible with a standard connector size, making them suitable for a wide range of applications. Socket blocks are often used in applications requiring external connection and disconnection of cables, such as robotics and machine setups.

Header Blocks

Header blocks are terminal blocks that feature two rows of pins or blades, where one row is used for input and the other row is used for output. Most header blocks are vertically polarized, meaning that the pins in each row are staggered in order to ensure proper electrical connectivity. Some header blocks also feature a top clamping system for secure tightness. They are typically used for making patch cables, wiring between cabinets or racks, and other high-density wiring applications.
