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 Kit Version
A2K
-
The A2K 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 A2K 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).

T7
-
The T7 is available in several interface and protocol options. The physical interface can be RS232, RS485 or US Digital's CAN (Controller Area Network). The protocol can be either US Digital's serial protocol or Modbus RTU. The RS232 version supports a single T7 with up to 100 ft of cable. For users that need longer cable lengths or multiple T7s on a single bus, the RS485 or US Digital CAN (Controller Area Network) version can be used. The USD-CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the CAN network cable. The host accesses the USD-CAN T7s through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple, easy serial port commands, just like the RS232 version. The RS485 version supports up to 32 T7s on the bus.
