Introducing the MA3

issue44_ma3.jpgVancouver, WA - Vancouver, WA - US Digital is proud to announce the release of its latest miniature absolute magnetic shaft encoder, the MA3.

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 (MA3-A) 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 width duty cycle that is proportional to the absolute shaft position. PWM output is available in 10-bit (MA3-P) and 12-bit (MA3-P12) resolutions. The accuracy is the same for both resolutions, even though the 12-bit version offers higher resolution.

Next Generation
US Digital continually seeks to improve our products by making them smaller, faster, more accurate, and lower cost. We found a way to make the current MA2 even smaller by changing the connector from 4-pins to 3-pins. This new product became the MA3 and only has a diameter of 0.48". This next generation MA3 product is recommended for all new designs and applications.
