Terminal Blocks - Accessories - Marker Strips

Marker strips, also known as 0805221, are essential components of terminal blocks which allow for easy identification of terminals within the blocks. These strips are usually composed of a plastic or metal material which has a low electrical insulation electricity that is 25 volts or less and a temperature threshold greater than 80 degrees Celsius. They are primarily employed for the purpose of connecting two separate electronic and electrical circuits.

Application Field

These strips are utilized in instruments, such as household appliances, laboratory equipment, computers, office machines, and robots; they are also used in the fields of communications, medical, transportation, and military. Commonly, the strips are applied in automotive industry, electronic industry and the production of outdoor lighting fixtures. Furthermore, they are applied in energy management systems, monitoring, controlling, and data acquisition, as well as in rail and maritime industries.

Design and Construction

The design of marker strips is important in assuring they are suited for their relevant application. Generally, they are manufactured by stamping a punched metal or plastic strip into desired shapes. The stripped portions of the metal or plastic can be knurled for holding and connection purposes, while the edge of strip is usually chamfered to form a sharp edge which can be used for marking purposes.

The design of 0805221 also incorporates features that protect against any environmental and operational hazards. These features include the use of insulation material that has the capability to protect against current overloads as well as excessive humidity or temperature. Most of these strips are also designed to be moisture and oil resistant in order to increase their overall durability.

Working Principle

Conventional marker strips operate using a process of plug and play, which makes it a breeze to get started. They can be easily mounted onto any device, such as the terminal block, with a simple manual insertion and removal, thereby eliminating the need for complex electrical tools or manual wiring. Additionally, Marker strips have the ability to recognize the numerical indexes printed on the strips, thus allowing them to identify the terminals from one another and allowing for straightforward installation or changes of any particular one.
