Terminal Blocks - Barrier Blocks

Barrier blocks, such as 0387098418, are a type of terminal block used to limit access to certain control circuits and wiring by providing a visible physical barrier. Its basic design includes two metal strips that intersect each other at a 90 degree angle and with insulated material in between.

Application Field

Barrier blocks are used extensively in almost every kind of industry, from military, digital signal processing, telecommunications and general programming to audio and video production. In addition, barrier blocks are ideal for places where large numbers of wires have to be connected quickly and securely, such as in robotics and similar automated machines.

Barrier blocks help in protecting delicate electronic devices from damage by isolating the circuitry. They are also used for troubleshooting, as the barrier blocks can be easily disconnected and reconnected without disconnecting cabling already connected. This is a particularly handy feature in any kind of industrial space.

Working Principle

A barrier block works the same as regular terminal blocks, however, only one terminal is accessible, instead of the two on each side as with regular terminal blocks. Instead of two levers, one is used to open and close the barrier block. A lever in the center of the block enables access to the circuit wires, while the other lever closes the block, effectively isolating the wires again. This is, of course, much safer than regular terminal blocks, as the wires are always protected.

Barrier blocks are available in various sizes and shapes. Common sizes are 0.375 inch wide and 0.500 inch or 0.625 inch for standard rectangular blocks and 0.250 inch or 0.375 inch for square blocks. The larger size blocks are often used in industrial equipment or where there is a higher number of circuits involved.

Barrier blocks also feature a removable connector with terminals at both ends, allowing them to be used in combination with other terminal blocks. This is especially useful in control systems where various electrical devices are connected to a single terminal block. This combination enables the systems to be more reliable and easier to maintain.

Barrier blocks are also highly cost effective and require minimal maintenance. This makes them an ideal choice for a wide range of applications, both in industrial and commercial settings. Whether it’s for power management, visual isolation of control circuits or to provide secure connections, barrier blocks are an invaluable tool.
