Magnetic encoders

Bearing-free magnetic encoder systems

The heavy industry demands encoder solutions which deliver reliably process control signals over many years. This is required in the face of the harshest conditions resulting from heavy loads such as mechanical shock, vibration, extreme temperature, dust, dirt and fluids. Each and every unplanned downtime causes high production losses. Applications in the field are either unsuited or it is simply not possible to fit encoders with optical scanning. The reasons are generally to be found in installation situations, for example extremely confined spaces, no free shaft end or large shaft diameters. And that in conjunction with excessive axial and/or radial shaft excentricity.

With the experience of installing thousands of applications in heavy industry across the globe Johannes Hübner Giessen, the specialists for genuine heavy duty encoder solutions, now offers the ideal solution in form of its modular, bearing-free magnetic encoder system MAG.

Product overview

  • MAG Incremental

    MAG Incremental

    Die lagerlosen, magnetischen inkrementalen MAG Drehgebersysteme sind besonders flexibel und bieten dank der Ausführung mit Polrad und Abtastkopf ein Höchstmaß an konstruktiver Freiheit.

  • MAGA Absolute singleturn

    MAGA Absolute singleturn

    The bearingless, magnetic absolute encoder systems MAGA are particularly flexible and offer a maximum of design freedom thanks to the design with pole wheel and scanning head.

  • Protection covers for split pulse wheels

    Protection covers for split pulse wheels

    A well-established solution for our magnetic encoders with a one-piece pulse wheel is now also available for our MAG/MAGA series with a split pulse wheel: high-quality protection covers made of stainless steel or carbon fiber reinforced plastic (CFRP), which reliably protect the pulse wheel and thus significantly extend its lifetime.

  • MAG Ex Incremental / MAGA Ex Absolute

    MAG Ex Incremental / MAGA Ex Absolute

    The explosion-proof encoder systems MAG Ex incremental with HTL or TTL output signals are available with immediate effect. Ex certification for the encoder systems MAGA absolute with SSI output signals is in preparation.
