Terminal Blocks - Barrier Blocks are found in the core of electronic devices such as industrial machinery, computers, electronic gadgets, and satellites. In many modern devices, they are the backbone of the design and control the flow and direction of current and signals around the device.

The particular Barrier Block number referenced in this article is 325141-12-0. This Barrier Block is a “15mm” type with barriers in between the contacts for added safety. 15mm refers to the panel cut-out size, or the hole which is cut out in the panel that the Barrier Block fits in to. There are various sizes of Barrier Blocks, and the 15mm type is one of the most common.

Barrier Blocks can range from one contact terminal per side, up to many dozens depending on the model. With an increasing number of contacts per side of a Barrier Block there is an increased number of potential applications and uses for that Barrier Block. This particular Barrier Block has 12 contacts per side.

The 325141-12-0 Barrier Block offers great versatility for applications ranging from very small units such as Sat Nav devices and machines used in manufacturing medical products, all the way up to full scale industrial machinery. The 12 contact terminals offer the user flexibility in controlling a multitude of signals and currents. It offers a range of features such as semi insulated solutions for higher operating voltage and environmental protection.

Working principle: The Barrier Block is used to create a “junction point” for several signals or cables to join. It is basically like a mini junction box. The Barrier Block allows for several wires or cabling/terminals to be connected with each other, with a barrier or insulation in between each station. This creates a single point for cabling that maintains multiple signals or currents in different directions.

The Barrier Block terminals are connected to each other with a calibrated screw tension or “finger proof” connection. The insulated area in between each contact point creates an isolation between them, providing electrical containment of the wires or cables. With this method of termination, it allows the user to build panels which are robust, durable and reliable, as the connections are very important to ensure a good quality build for a panel.

In conclusion, Barrier Blocks are an integral component of the signal transmission and control of the electric current and signals in the devices we use on a daily basis. The 325141-12-0 Barrier Block can be used in a wide variety of applications due to its versatility and safety features. It operates absolutely in accordance with a “junction point” principle, which is to give the user the flexibility to connect multiple devices and cables together with one connection, whilst still maintaining the insulation between each contact.
