Miniature Absolute Magnetic Shaft Encoder
The MA3 from US Digital is a miniature absolute magnetic shaft encoder that provides shaft position information over 360° of rotation with no stops or gaps. The encoder 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. 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.
