Lika Electronic present SMAB, the absolute bearingless encoder with flat ring and through hollow shaft suitable for large diameter applications and harsh environments. SMAB bearingless absolute encoder + MRAB flat ring combines the advantages of the shaftless design with the benefits of the contactless and wear-free magnetic scanning. It is distinguished by its 6 mm-thick flat ring with large through hollow shaft (80 mm bore) and the unconventional installation. The poles in fact are oriented axially and the low profile sensing head is mounted over the flat surface of the ring instead of radially as usually.
SMAB encompasses fully overmoulded electronics with up to IP69K protection rate and guarantees great resistance to dust, liquids, shocks, and vibrations as well as immunity to contaminants and interference. Furthermore it affords excellent durability under adverse conditions and even wash down applications. Comfortable mounting tolerances make installation easier.
SMAB has a resolution of 16 bits (higher resolutions on request) and provides the absolute information through the SSI interface. Along with standard functions such as preset and counting direction, it also delivers warning and error bits. In addition it is fitted with an integral LED to signal correct operation and alignment. Cable and M12 connector outputs are both available.
By virtue of the compact slim design and the high rotational speed, SMAB modular encoder is perfect for position control of motors, direct drives, industrial robots, and constricted space applications.
