Terminal blocks, also known as terminal boards or strips, are fastening and connecting devices that connect two electrical conductors. In other words, they are used to connect electrical wires or devices. A marker strip is an accessory on terminal blocks that identifies the connection point on the left, considerably simplifying the subsequent wiring. The application fields and working principles of marker strips are as follows.

1. Applications

Marker strips are mainly used in the wiring of control cabinets and terminal blocks. It is possible to assign individual function names and labels to the connected points, making the subsequent wiring and maintenance simple and efficient. Their application fields mainly include power distribution, factory automation, city power systems, communications, and instrumentation.

2. Features and Benefits

Marker strips are suitable for harsh environments, with their high fire protection compatibility, enhanced weather resistance and increased abrasion resistance. The strip offers outstanding corrosion protection due to its special material. Its insulation-molding technology can effectively prevent electrical short circuits, preventing accidents at work sites. Additionally, its clear and concise marking and designation enables easy and convenient identifications even for complex wiring. Moreover, due to its special abrasion-proof and weather-resistant materials, the marker strip has a long life.

3. Working Principle

Marker strips, as accessories for terminal blocks, are usually divided into two strips, the top strip for labeling and the lower strip for lettering. The working principle of marker strips is based on marking or writing to make the letters and names on it. The writing materials depend on the strip’s printing method, using liquid printing, sublimation printing, screen printing and laser etching. After marking and writing the names of each terminal, the markers are connected to a control cabinet with stainless steel screws and plastic connectors.

In conclusion, marker strips, as accessories for terminal blocks, are widely used in power distribution, factory automation, city power systems, communications, and instrumentation. With their excellent features and benefits, marker strips are designed to make sure the safety of workers. In addition, the marker strip is easy to install and stays in place for a long time due to its durable construction. Therefore, marker strips are the ideal choice for application in harsh environments.
