The SMA2 is the linear absolute encoder capable of gaining the top of Lika’s range thanks to the many new features and improvements. It is ideally suited for applications where small size and fine resolution are mandatory such as linear motors, product handling equipment, pick & place robots and lines, electronic assembly systems, printing and measuring machineries, electro-medical instruments, machine tools.  This slim magnetic scale system is designed to provide both the absolute and the incremental information. Fitted with a polymer ferrite composite media, the magnetic scale is magnetized with two tracks: a true absolute track for position information and a 2 mm (0.08″) pole pitch incremental track for speed feedback.

It has been narrowed to a width of only 10 mm (0.39″) while the measuring length has been lengthened up to 8 m (26.2 ft). The scale is insensitive to dust, oil, grease, water and most common chemical agents; thus the measuring system will reliably operate in the most aggressive industrial environments.  Also, the dimensions of the sensing head have been minimized; the enclosure is very compact and slim, yet preserves its durability. It encapsulates the Hall sensors, the incremental sensor and the miniaturized electronics and guarantees IP67-rated environmental protection along with immunity to contaminants and interference.  By virtue of the non-contact operation, the SMA2 is  virtually wear and maintenance-free, and ensures unparalleled reliability over time. The new advanced sensor produces high resolution up to 1 µm and enables velocities up to 7 m/s (23 ft/s).

The encoder delivers absolute information through the BiSS-C or SSI interface and the incremental information through the NPN o. c. output circuit. SMA2 encompasses only first-rate components and high-flex cables especially suited for use in cable drag chains – tested for more than 1 million cycles.
