Terminal blocks - Din Rail, Channel

Terminal blocks are a type of electrical connectors widely used in the industrial and commercial worlds. They are used to create electrical connections between electrical components with relative ease. Of the many varieties of terminal blocks, Din Rail and Channel type blocks are the two most common types. This article will discuss a few features of both the Din Rail and Channel type terminals and their respective advantages and application fields.

Din Rail Terminal Block

Din Rail Terminals sport a 19 mm rail that is specifically designed to be placed in DIN rails typically mounted on an enclosure. This type of terminal block is widely used in industrial and commercial applications since the DIN rail allows for easy installation and holding of the terminal block. These terminal blocks usually are engineered to provide reliable contact between 2 connections over large temperature ranges. Since the Din Rail terminals are separate pieces, they can be easily removed and replaced without affecting the wiring in the installation.

The Din Rail terminals commonly come with a range of features such as current-carrying capability, power-control capacity, multiple connections and quick connectors. They are typically designed from UL94V-0 rated nylon and inherently enhance the robustness of the electrical connection. Moreover, they come with contact bridging options which make serial connection easier with minimum wiring lengths.

Channel type Terminal Blocks

Channel type terminal blocks are a type of terminal blocks that are designed to be placed in an open environment and mounted on a flat surface. This type of terminal block allows for space-saving designs and easy wire entry. Channel type terminals usually come with a variety of features such as current-carrying capability, signal integrity, multiple connections and polarized sections. As with the Din Rail terminal blocks, the channel type terminal blocks also come with contact bridging options for serial connection.

The channel type terminal blocks come in a wide range of sizes and colors, making them ideal for customized electrical assemblies. The ease of wire entry is especially useful in the case of multiple connections, as it enables the use of smaller wiring lengths without compromising the overall performance. Moreover, the terminal blocks are designed with lower contact pressure so as to minimize the chances of shorting of connections.

Application Field and Working Principle

The application field of terminal blocks can range from industrial equipment to residential devices. The Din Rail and the Channel type terminal blocks are particularly used in the industrial and commercial sectors, where there is a need to safely and efficiently direct power supply and signal transfer between electrical components. The working principle of the Din Rail and the Channel type terminal blocks is quite simple since they both come with the same basic design. Both of them have fixed contacts mounted onto a body and when wiring is conducted between the contacts, a secure and reliable connection is formed.

In addition, both the Din Rail and the Channel type terminal blocks also come with options for bridging contacts, which enable them to be used as separate sections for multiple wiring connections. This feature enhances the overall efficiency and performance of the terminal block connection.

Conclusion

In conclusion, the Din Rail and the Channel type terminal blocks are two of the most commonly used varieties of terminal blocks. Both of them are designed for user-friendly installations while ensuring a reliable and secure connection between two points. The Din Rail terminal blocks are typically mounted on an enclosure while the Channel type terminal blocks are usually installed on flat surfaces. Both types of terminal blocks come with multiple features such as current-carrying capability, high-speed signal transfer and contact bridging that make them suitable and reliable connection solutions.
