Selector Magnet Set for Otis  Reader Boxes – Magnet & Holder

Magnet set (21 × 10 × 40 mm) for Otis A7003AT/A7003AW/7003BB/AAA25500AAA reader boxes; choose standard holder or curved tab lodgment.

This selector magnet set is designed specifically for use with the Otis reader boxes A7003AT, A7003AW, 7003BB, and AAA25500AAA. The core magnet measures 21 mm wide × 10 mm high × 40 mm long, providing consistent magnetic detection performance in the selector tape system. You have the choice of two mounting configurations: either the magnet plus a standard straight holder (housing) or the magnet plus a curved holder featuring a tab (lodgment) that assists in locating and securing the magnet assembly in the reader box mounting groove.

This kit is ideal for replacing worn or damaged magnets in older Otis floor selector systems. It ensures proper alignment in the reader box channel and accommodates either the standard straight positioning or a curved alignment with tab for improved retention and positioning. The holder materials are engineered for elevator selector environments and resist shop‑floor contamination and vibration. Sold as a complete assembly (magnet + chosen holder) for immediate installation.
