Terminal Blocks - Accessories - Marker Strips

Marker strips are terminal blocks that come in many different sizes and types, to meet a range of application requirements. They are used to mark circuits, to reduce set-up costs and installation times, allowing for faster and easier wiring connection changes. Terminals are printed with a single block or markers can be applied to existing blocks.

For industrial applications, marker strips for terminal blocks come in 12 mm, 24 mm or 32 mm sizes. They are suitable for single-phase or five-phase power distribution systems and for mounting onto insulating and shielding DIN rails.

For automation and process control applications, marker strips are used to identify circuits in control panels. They are available in 8, 12 and 18 mm sizes and feature a range of legends, colors and a variety of marker types.

The main application fields for marker strips are commercial buildings, telecommunications equipment installations, industrial plants, motor control centres, process control centres, automotive manufacturing and automated warehousing.

Working Principle

Marker strips are made up of two components: the sleeve and the block. The block is inserted into the sleeve and when it reaches the base of the sleeve, its edges are locked into place by the mounting posts. The mounting posts also serve to disconnect the two components when needed.

The marker strips have an identification marking or legending on one side which is visible from the outside. The opposite side is flat and designed for electrical connections. The legending can be a printed label, a die-stamped numerals or letters, or a printed inkjet label.

Connections can be made between two marker strips using a variety of tools, such as horizontal or vertical terminal presses, clamps or screwdrivers. The marker strips must be inserted into mating blocks which are connected to the relevant wires in the terminal blocks.

Marker strips are available in several sizes and colours, to suit specific application needs. The marker strips can also be supplied with different types of mounting holes, depending on the particular application.

Conclusion

Marker strips for terminal blocks are used for a range of industrial and automation applications, for identifying circuits and making connections between them. They offer easy installation and low setup costs. Marker strips are also widely used in telecommunications and automotive equipment installations, as well as in commercial buildings.
