Allegro MicroSystems A1262
The A1262 is a two channel, latching Hall-effect sensor IC that features both vertical and planar Hall elements. The vertical and planar Hall elements feature sensing axes that are orthogonal to one another and provide 90° of phase separation for ring magnets that is inherently independent of magnet pole spacing and air gap. The 2D architecture of the A1262 simplifies the design of motors and magnetic encoders by providing quadrature output signals in a very small footprint.| Part No. | A1262 |
