The MA3 is a miniature rotary absolute shaft encoder that reports the shaft position over 360° with no stops or gaps. The MA3 is available with an analog or a pulse width modulated (PWM) digital output.
Analog output provides an analog voltage that is proportional to the absolute shaft position. Analog output is only available in 10-bit resolution.
PWM output provides a pulse duty cycle that is proportional to the absolute shaft position. PWM output is available in 10-bit and 12-bit resolutions. While the accuracy is the same for both encoders, the 12-bit version provides higher resolution.
Three shaft torque versions are available: high torque (-D option), low torque (-N) and ball-bearing (-B). The high and low torque versions have a stainless steel shaft and brass bushing lubricated with grease to provide ideal torque for panel mount, human-interface applications. The ball-bearing version has a brass shaft and miniature precision ball bearings suitable for high speed and ultra low torque applications. The ball-bearing version is only available with a 1/8" shaft diameter.
Connecting to the MA3 is simple. The 3-pin high retention snap-in 1.25mm pitch polarized connector provides for +5V, output, and ground.
