Terminal Blocks - Accessories - Marker Strips

A marker strip is a fundamental component of a terminal block system. It is a narrow strip of metal or plastic with small printed markers, usually arranged in a specific order. They provide a way to identify the functions of the connections in a wiring system. Marker strips are designed for quick and easy installation, and they can be adapted with various connectors for varying applications.

The most common type of marker strip is a clip-on type. It comes with snap-on lids for attachment to the box or plate. The clip-on type provides a secure fit for permanent mounting, but it also allows for easy removal when necessary. Another type is a slide-in type. This is a two-piece design with a backplate that slides into a groove in the box or plate. It offers good securement and protection against vibration, but requires a slightly larger size.

Sometimes, special marker strips are needed for applications where the electrical system is complex, such as on automotive or medical equipment or with special connectors. In those cases, more elaborate marker strips are often used. These may include multiple rows of circular holes for different types of connectors, or multiple slots for other types of connections. They can also include connector loading points or areas for identification and labeling.

Marker strips have a variety of different prints to accommodate various specifications and requirements. These include numbers, letters, and symbols that identify the connections and functions. Many of these printed markers will provide additional information such as current rating and electrical characteristics of the connections. The most common type of print used is the number-letter combination, to provide both quick identification and technical information about the connection.

Marker strips are also available in different colors depending on the application. Generally, black is the most common color for general wiring, but they can also be found in red, yellow, and green. The colors can help to distinguish different types of wiring and connections, and they can also help in identifying failures during maintenance.

In addition to the prints and colors, marker strips are available with clip-on or slide-in fittings. Clip-on fittings provide a secure fit for permanent mounting but allow for easy removal when necessary. The slide-in type is a two-piece design with a backplate that slides into a groove in the box or plate. This type offers good securement and protection against vibration, but requires a slightly larger size.

Marker strips are an essential component in any wiring system, providing an organized, easy to read guide for connection options and system identification. The variety of prints, colors, and fittings make them exceptionally versatile, and they can be adapted to fit almost any type of application.
