Terminal Blocks - Accessories - Marker Strips - application field and working principle

49039YELLOWSP Marker Strips are a kind of easily recognizable electronic terminal block accessories that help identify connected electronic components. The marker strips allow for a quick and efficient connection and are largely used in the aviation, railway, auto and shipbuilding industries. They are also widely used in telecommunications, medical and food industries, and various other fields.

49039YELLOWSP Marker Strips are composed by molded plastic, circuit board, and stepper motor. We focus in this article on the working principle of these components.

Molded plastic

The upper part of the marker strips is made of molded plastic, which is needed to prevent vibration when working. The plastic is self-lubricating and highly resistant to external forces. This ensures high current carrying capacity and durability.

Circuit board

Marker strips are equipped with a printed circuit board. This board is connected to the terminal blocks and each terminal block has its own printed circuit board. This helps to quickly and simultaneously connect the terminals to their respective elements. Furthermore, this circuit board allows for concurrent operation of multiple circuits connected to the same signal lines.

Stepper motor

The stepper motor in the marker strip helps to ensure that the terminal blocks are properly connected. The motor itself is composed of a shaft that rotates at different numbers of revolutions based on the position and direction of the terminal connectors. The stepper motor helps to accurately and securely close contacts and maintain their current carrying capacity.

In order to ensure proper operation, the installation should be performed in accordance with the instructions handled by the manufacturer. It is also highly recommended that maintenance checks are performed on a regular basis.

49039YELLOWSP Marker Strips are a reliable and efficient solution to make quick and long lasting connections between terminal blocks. They provide high current carrying capacity and are suitable for a variety of applications in different industries.
