The MA3 is a miniature absolute magnetic shaft encoder that provides shaft position information over 360° of rotation with no stops or gaps. The MA3 is available in two output versions, analog and pulse width modulation (PWM). The analog version outputs a voltage that is proportional to the absolute shaft position. PWM output is available in 10-bit (1024 positions) and 12-bit (4096 positions) resolutions and outputs a variable pulse width proportional to the shaft position. Absolute encoders have traditionally been larger, more expensive, and more complex than incremental encoders. In contrast, the small size, low cost ($29.00 / 1 piece price, $21.00 / 100 piece price), and simplicity of the MA3 now provides absolute position feedback for a new spectrum of applications that would otherwise be impractical. Typical applications for the MA3 include front panel control, camera pan-tilt position sensor, rotary valve position sensor, rotary air duct valve position sensor and studio lighting position feedback.
