Siemens 3SB1904-2MF Labeling Plate For Label Holder

Siemens 3SB1904-2MF is a silver-colored inscription labeling plate sized 17.5 × 28 mm that snaps onto the matching label holder used with Siemens 3SB-series devices. It features black lettering and the graphic symbol O I O I on its surface, providing a compact, high-contrast inscription for panel labeling. Designed specifically for attaching to the label holder, this plate gives technicians a durable, pre-printed inscription that stays legible in production environments. The 17.5 × 28 mm format is tailored to fit the designated labeling area on the label holder, helping keep control panels organized and readable at a glance.

Suitable for use on Siemens automation panels that employ the 3SB labeling system, this plate conveys function or status through its pre-printed symbol and text, contributing to safer, more efficient operation.
