With this type of terminal block, you only need one large wire to be connected to your input terminal. To distribute power from one input source to multiple outputs and devices, a power distribution block provides a safe and efficient solution. With one input and one output contact, this is a type of terminal block that allows you to feed two different wires into opposite sides of the block. Feed-through terminalsįor applications where two wires are to be joined to establish a wire-to-wire connection, a feed-through terminal block is a convenient solution.
Phoenix Contact terminal blocks are among the popular PCB mount terminals we offer at Allied Electronics, along with other leading manufacturers. This housing is then soldered to a circuit board. With this option, bare wires are inserted and clamped inside the housing. PCB mount terminals are also known as Eurostyle or wire-to-board connector blocks. As such, it creates ‘barriers’ – or insulating blocks – between each terminal. Used in settings where vibration can be an issue or to avoid a potential short circuit, there is often more than one termination point for cables. Just as some standard terminal blocks use screws to hold the cables or wires, barrier terminal strips do so too. Unlike other single-level feed-through terminals, ground terminal blocks are grounded to where they are mounted e.g. Their role is to ground wires or systems for safety reasons and help to prevent interference from electrical or other signals. The design of ground (or earth) terminal blocks makes it possible to interchange with standard terminal blocks. Here are some device types that can be supplied by Allied Electronics: Ground terminals Having knowledge of the type of connector block you need is essential to the performance of any industrial circuit or system. Not all terminal blocks are the same and there are different types, which are classified by their construction and intended application. Are there different types of terminal blocks? As such, terminal blocks are cost-effective power distribution solutions for commercial and industrial systems.
This can be for testing, wire replacement, safety inspections, and maintenance. Due to the way in which they create the connection, it is easy to insert and remove a wire. Terminal blocks can prove extremely useful where there are semi-permanent connections. It is this frame that also provides a ground for the circuit – creating safe conditions for a circuit to terminate and reducing the risk of a short circuit. The connection is then made by a metal strip found within the insulating plastic frame. In their simplest form, terminal block connectors are arranged in a linear configuration – with each terminal connecting to a single pole. Terminal blocks can also be used to connect switches and outlets to mains power sources. With its insulated construction, the components can distribute electrical power around a circuit (or to another one) safely and effectively. What are terminal blocks and strips?Ī terminal block or strip is a modular electrical connector that is designed to connect a single incoming wire to multiple outgoing wires. Search our huge range of terminal blocks for the type, mount, and configuration you require. It means that you can trust us to supply terminal blocks to your exact specifications every time. We stock components and accessories from class-leading manufacturers including Phoenix Contact and TE Connectivity. No matter the industrial application or electrical load-bearing requirements, Allied Electronics is proud to offer a vast selection of connector blocks to meet all needs. From energy technology to railway rolling stock, terminal blocks – or terminal strips – are the connectors that provide that assurance. In motion and automation control systems, the need for safe and reliable connections between multiple electrical wires and circuits is clear.
