MP55 Industrial Absolute Optical Rotary Encoders With BiSS-C Interface 0
● Full-scale true multi-turn encoder composed of precision reduction gears, no battery needed, power-break memory; any position within the range is unique, even if there is interference or movement after power break, the number of turns will not be lost .
● All parameters can be set through the communication of the computer, and the zero position can be set at any position, so when installing the encoder, the equipment can stay at any position, the connecting shaft can be fixed without considering the rotation position of the encoder, and can be automatically corrected by a zeroing operation at the external lead or through RS485/SSI BiSS-C  communication.
