Absolute Encoders
US Digital designs and manufactures absolute encoders in both optical configurations, for the highest possible resolution and accuracy, and magnetic versions for demanding environments. In either case, absolute encoders report a shaft angle within a single 360-degree shaft rotation without stops or gaps. Unlike incremental (sometimes called "relative") encoders, absolute encoders provide true (absolute) shaft position, eliminating the need for a "home" or "zero" cycle after a supply-voltage power cycle.

Absolute Magnetic Kit Encoder
MAE3
The MAE3 is an absolute magnetic kit encoder that provides shaft position information over 360 of rotation with no stops or gaps. This magnetic encoder is designed to easily mount to, and dismount from, an existing shaft to provide digital feedback information. The MAE3 is available with an analog or a pulse width modulated (PWM) digital output.

Absolute Optical Encoder
A2
Product DescriptionRestriction of Hazardous SubstancesThe A2 absolute encoder is a non-contacting optical rotary position sensor which reports the shaft angle within a 360 deg. range. As opposed to incremental encoders, the A2 reports the absolute position rather than the change in position. When powered up, it does not require a home cycle, even if the shaft was rotated while the power was off. In multi-turn mode, it tracks the position in a 32-bit counter as long as the power supply is maintained. Internally, an infrared LED flashes through a circular bar code onto a linear array sensor. The microcontroller decodes the image into a unique position. All user programmable parameters such as resolution, origin, direction and mode are permanently stored in an internal EEPROM
