Terminal Blocks – Barrier Blocks

A38930807 is one of the most widely used and useful type of terminal blocks. Generally referred to as Barrier Blocks, they offer the ability to connect two or more wires together within an enclosure. The name derives from the fact that a physical barrier, typically a pluggable tab or a removable door is mounted on the terminal block.

These barrier blocks provide a greater level of safety compared to a standard terminal blocks, and are used in applications where multiple wires need to be connected while also preventing accidental contact or shorting of the wires. This is accomplished by having the barrier block physically separate the wires and prevent inadvertent access to the terminals. Additionally, these terminal blocks are isolated and designed to ensure that even if the wires were to become disconnected, they would not short each other.

The barrier block also has a number of different uses. It is commonly used to connect multiple sensors or other control devices in a control system, where the barrier blocks provide a convenient and safe way to connect the various components. Additionally, they can also be used to provide a method of quickly changing wiring in a machine tool or an RFID system. In this case, the barrier blocks provide an easy means by which the various connections can be modified without having to physically rewire the device.

In terms of construction, the barrier blocks are usually constructed of die-cast aluminum or plastic. The connectors themselves are typically made of brass, with some models also featuring plastic housings for additional protection against corrosion. The terminals are typically locked in place with screws, and the barrier can be mounted in a variety of orientations.

In terms of cost, barrier blocks are generally significantly more expensive than standard terminal blocks. This is due to the added safety and protection that they provide, as well as their ability to quickly and easily isolate individual circuits from each other. Additionally, they are available in a variety of sizes and configurations, depending on their intended application.

As the name suggests, the A38930807 Barrier Block is able to provide a safe means by which to quickly and conveniently make multiple connections without putting any of the wires or components in danger. Its construction and design offer reliable performance, while its versatility and cost make it an ideal choice for a variety of applications.
