Label plate Siemens 3SU1900-0AD16-0AA0 square 27×27 mm unmarked

Siemens label plate 3SU1900-0AD16-0AA0 is a square, unmarked identification plate with external dimensions of 27×27 mm. It offers a blank, durable surface intended for custom marking or labeling on control panels, operator stations and retrofit applications. The compact 27×27 mm format is compatible with standard control and signaling device housings and allows users to apply their own text, symbols or adhesive markers as required.

Advantages

The unprinted plate provides flexibility for custom identification, enabling consistent labeling across panels without pre-set text. Its square shape and precise dimensions ensure reliable fit with devices and cutouts designed for standard 27×27 mm plates. The neutral appearance integrates with industrial environments and operator interfaces while simplifying inventory management by reducing the need for multiple pre-printed variants.

Suitable for

• Custom marking of control and signaling devices
• Replacement plates in maintenance and retrofit work
• Operator stations and machine panels requiring standard-size identification
• Applications where blank plates are required prior to on-site labeling
