SMA3 is the new bearingless absolute encoder from Lika Electronic. It is designed in a compact readhead with a diagnostic LED and can be installed either in rotary applications or in linear applications. Whether it is coupled with a ring or with a magnetic tape, it offers great flexibility and several competitive advantages.
SMA3 can reach very long linear measuring lengths, up to 2.5 m / 8.2 ft in the first stage and will be increased up to 20 m / 65.617 ft afterwards.
SMA3 is not bound to defined pole pitch dimensions. In most applications, the pole size can be limiting because the diameter of the ring depends on the width and the number of the poles and may not match the needs of the specific application. SMA3 does not place limitations on the construction or diameter of the ring so it can be made to perfectly fit most applications.
In addition, the SMA3 features a high counting frequency up to 200 kHz, which allows the measuring system to reach counting speeds much higher than those of competing products in the market. SMA3 is also easy to install thanks to the wide mounting tolerances larger than 1 mm / 0.039”.
SMA3 offers a resolution down to 0.5 µm and provides both the absolute information for position feedback through BiSS-C and SSI interfaces and additional incremental information for speed feedback. SMA3 is designed for demanding position and motion control applications and provides high performance and reliability in many industrial sectors.
