SMAH2 bearingless absolute encoder is designed to operate on very large shafts with diameter up to 2.6 m / 8.53 ft. It must be paired with a flexible magnetic tape which is secured to the circumference of the drive shaft. The tape can have a length of up to 8.1 m / 26.57 ft., according to needs, and is only 10 mm / 0.39” wide.
It fits perfectly and easily on very large shaft applications, also in constricted spaces, such as wind generators, turbines and hydroelectric power plant machines, rotary tables, cranes, construction machinery, steel mills, paper machines, textile, wood, metal & stone working machinery, etc.
The ends of the tape are open and must be clamped together around the shaft, so the measuring system is perfect for retrofitting since no disassembly of the existing shaft is required. Furthermore, it is able to read the absolute position even when crossing the joint area in the tape without any loss of counts.
SMAH2 is bearingless and contactless, its operation is wear- and maintenance-free.
The magnetic tape is insensitive to dust, oil, grease, water, and common chemical agents.
The max. speed allowed by the measuring system can be up to 2 m/s (RPM value depends on the shaft diameter; for example, it can be 38 RPM max. when the shaft diameter is 1 m / 3.28 ft.).
SMAH2 provides the position information with a resolution of up to 21 bits through the SSI and BiSS interfaces.
