The product is a label strip from the brand Phoenix Contact, type ZB 5,LGS:FORTL.ZAHLEN 121-130, with manufacturer number 1050017:0121. It is a 10-piece identification element specifically designed for use with terminal blocks having a width of 5.2 mm. Label strips serve for clear identification of terminals in electrical control systems, particularly in industrial electrical engineering, where quick and accurate assignment of wires to respective connection points is required. The labeling is applied lengthwise on the top surface of the strip, with numbers 121 to 130 printed consecutively. The strip is white, ensuring good readability of the black digits and enhancing visibility within the enclosure environment.

Label strip

The label strip is made of a flexible, durable plastic material suitable for industrial environments. The shape of the strip allows for secure mounting by snapping into the terminal, ensuring it is held firmly in place and does not accidentally slip off. The length of the strip is designed to cover the entire width of the terminal, ensuring clear identification of the connection point. The labeling is printed in a sans-serif, highly legible font, which remains visible even under low lighting conditions or from a distance.

Applications

The label strip is used in industrial electrical engineering, particularly in enclosures, control systems, drive technology, and machine wiring. It serves to identify terminals in rows of terminal blocks, where consecutive numbering enables systematic and unambiguous wire assignment. Its use is especially beneficial in complex control systems with a high number of connection points, where quick identification is essential for maintenance, servicing, and fault diagnosis. The white color of the strip provides high contrast against the black labeling, improving readability.

Functions and features in detail

The primary function of the label strip is visual identification of terminals. The consecutive numbering from 121 to 130 allows for structured labeling that can be adapted to existing identification systems. Installation is done by snapping, which secures the strip to the terminal without requiring additional tools or adhesives. The material selection ensures high mechanical stability and resistance to mechanical stress, such as during installation and maintenance in enclosures. The surface of the strip is smooth, allowing for easy cleaning and maintenance.

Technology explained simply

The label strip is a passive identification element that performs no electrical function and serves exclusively for visual identification. The labeling is applied lengthwise, meaning the numbers are arranged along the longitudinal axis of the strip, so they are oriented perpendicular to the terminal row when installed. The snap-in mounting method means the strip is inserted into a corresponding groove in the terminal and secured by a locking mechanism. This prevents accidental slippage and ensures permanent fixation.

Compatibility and accessories

The label strip is specifically designed for terminal blocks with a width of 5.2 mm. It is therefore compatible with terminals meeting this standard dimension, commonly used in industrial electrical engineering. Its use is independent of other components, as the label strip functions as a standalone identification element.

Installation and mounting

Mounting is done by simply snapping the strip onto the terminal. The strip is inserted into the designated groove of the terminal, where the locking mechanism automatically secures it. No additional tools or adhesives are required. Installation is quick and easy, reducing mounting time during enclosure wiring. The labeling is pre-printed, so no additional marking or labeling is necessary.

Individual strips are not available as single units, but only as a 10-piece set.

Operational benefits

Using the label strip enables quick and unambiguous identification of terminals, significantly simplifying maintenance and servicing of electrical systems. The consecutive numbering supports structured identification systems and reduces error risk during wiring. The simple snap-in mounting reduces installation time and labor effort. The white color and clear labeling ensure high readability, even in poorly lit environments. The material is durable and withstands the demands of industrial environments.
