These transducers provide separate digital outputs that provide information on X X magnet rotation speed, direction, and magnet pole count. These devices eliminate the major manufacturing hurdles encountered in fine-pitch direction-detection applications, namely maintaining accurate mechani- LOGIC T VCC is a C 1 2 3 4 5 SUPPLY DIRECTION GROUND E1 OUTPUT SPEED 1xKA PRODUxKA; Dwg.
