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 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

Absolute Optical Inclinometer
A2T
The A2T is a single axis, digital gravity angle sensor. The A2T serves as a full 360 range absolute tilt sensing programmable level with either digital or analog output. Internally, a rotary bar coded disk is mounted to a weighted gravity driven wheel. A micro-controller strobes an LED to transfer the bar code image onto an optical linear array, then decodes the position every 2 mSec. Magnetic damping provides fast response and settling time while virtually eliminating overshoot and oscillations. An internal EEPROM stores field programmable parameters such as resolution, zero position, direction swap, and mode. This second generation design virtually eliminates the primary accuracy limitation of first generation inclinometers, which is sitation (hysteresis).

Incremental Encoders
Versatile, compact and flexible – Incremental encodersIncremental encoders are used when retention of absolute position upon power loss is not required. These encoders provide information about the position, angle and number of revolutions. The number of lines per revolution determines the resolution. The current position can be determined by counting these pulses from a reference point. Upon activating the machine, a reference run to the reference point is required to determine the absolute position of the encoder.
