The AD58 is an absolute encoder with a true geared Multi-Turn and optical sensing technology: The mechanical design consists of two ball bearings and a flexible torque support. The AD58 is ideally suited for integration into BLDC servo motors for demanding Applications such as CNC precision machining and printing in professional quality. Through its low current consumption the AD58 is contributing to lowering cost of ownership.

Additional Information

N/A Fully digital control loop
The new and completely digital OptoAsic technology enables the transition to a truly digital drive system. The conventional absolute encoders still have analog sine wave signals for the feedback of speed and position data. The AD 58, however, provides fully digital position data up to 22 Bit ((Single-Turn)) and 12 Bit (Multi-Turn) over the BiSS interface with a variable clock rate up to 10 MHz. This corresponds a (Single-Turn) resolution of more than 4 million measured steps
