Absolute, high-resolution motor feedback sensor from SIKO

The MSAC501 absolute sensor from SIKO offers a truly absolute solution for measuring motor feedback. The exact sensor position is available immediately after a current interruption so additional reference or mechanical activity is not necessary.

The MSAC501 sensor works with standardized SSI or RS485 interfaces. An optional LD output for digital signal output is also available. Rim speeds of 25 m/sec (incremental) or 5 m/sec (absolute) can be easily realized. The MSAC501 has a system accuracy of up to +/- 0.06 ° (in combination with the magnetic ring MRAC501); resolution and repeatability can even reach +/- 0.0014 °.

All components are rated at protection class IP67 and can be used across a broad range of temperatures, from -30 to + 80° C. The sensor has a high contamination tolerance (dust, oil, grease), long working life, and resistance to wear thanks to the contactless, magnetic measuring principle.

As a “partner” for the MSAC501 sensor, the MRAC501 (solid aluminum ring) and the MBAC501 magnetic tape are available. The MRAC501 is available as a solid ring with fixed aluminum flange, and is therefore suitable for measuring revolutions up to 360 ° (single turn). The MBAC501 measuring tape includes a magnetic tape and steel carrying case, and is designed for self-assembly by the customer on a ring or external radius. With this combination, measurements can be conducted over a range of 360°.

These different components can serve a large variety of requirements, regardless of whether they involve different diameters of bottles, different interfaces, special resolutions, high accuracy demands, or simply extreme robustness with respect to dust and dirt.

The MSAC501 sensor is already available on the market and can be tested free of charge on request by contacting SIKO GmbH.
