Description

Installs onto shafts 12-bit resolution, and resolution field programmable Full 360 degrees range, 7 msec update time Low power drain of 18.5 mA max., and 2.5 mA in sleep mode Field programmable parameters such as setting zero position point (free demo software provided) EEPROM stores downloadable parameters Multi-turn mode (note: power must be maintained to prevent reset to zero) Product Description Restriction of Hazardous Substances The A2K optical encoder is a 12-bit absolute rotary kit style encoder that reports a shaft angle within a single 360-degree rotation of a shaft. The kit style A2K allows the encoder to be easily assembled onto an existing shaft and bearing assembly. Unlike incremental, sometimes called relative, style encoders, the A2K provides true (absolute) shaft position eliminating the need for a home or zero cycle after a supply voltage power cycle. The A2K communicates over a RS 485 style serial bus utilizing US Digital's SEI (Serial Encoder Interface), which allows for simple, quick and convenient networking of multiple SEI devices on a single network. PLCs, motion controllers, and computers can also reside on the SEI bus by using US Digital's SEI to USB interface device. For complete information about the SEI bus, please refer to the SEI Communications Protocol webpage. The A2K is also available with an optional analog output. The analog output option provides a maximum voltage range of 0 to 4.095 volts with 12-bit resolution. The output voltage can be scaled by simple SEI commands to provide user-defined voltage ranges. From the factory, the analog output voltage is set to 0 to 3.599 VDC range.
