    The encoder ALS 40 or FGL 40 from Hübner Giessen is a specially developed encoder for most extreme environment conditions like we have at the looper of a hot strip mill.

    In rolling mills loopers are normally used to control the tension of the metal strip between roll stands. The rotational angle of the looper is measured by a feedback encoder designed to meet special requirements. The slight swing motions of the looper result in an unfavourable grease distribution in the ball bearings and thus in an insufficient built-up of a lubrication film formation. At nonmoving shaft high vibration loads can additionally contribute to local fatigue of the raceway and aging of the lubricant film. On site the encoder is furthermore subject to oil/cooling emulsion/water. The standard encoders used to date by customers have been unable to offer the required service life.

    Modular universal encoder system with up 10 functions in one unit: Speed, position, electronic overspeed switches, electronic position and cam switches, diagnostic and others.

    The U-ONE® is based on an universal basic unit connected to electronic function modules in the switchgear cabinet via optical-fiber cables that are immune to EMI. Alternatively, a compact version is available. There the electronic function modules are just backpacked to the detection unit.

    The electronic function modules are linked by an internal bus structure.

    A large number of possible electronic function modules results in high planning flexibility and easy expandability for later additional requirements. This concept offers considerable cost savings, thanks to its simple mechanical fitting, standardized electronic function modules, and reduced wiring requirements.

    Advantages at a glance:

    - Compact design

    - Central programming with self explaining software (Teach-in programming)

    - Extreme reduction of cable costs

    - Extreme reduction of commissioning time

    - Easy to extend (fiber optic version)

    - High flexibility

    - Saving spares


  • Incremental encoder
    Incremental encoder for speed control of main and auxiliary drives. Reliable.Precise.Flexible.
    Hübner Giessen provides a wide range of incremental encoders for all applications at the steel mill process as well as EOT cranes in the steel plant.

  • - Solid shaft

    - Hollow shaft

    - NEMA C-Face

    and many more different types.

    - All possible signal outputs available such as HTL, TTL, SIN/COS

    - CE, UL, CSA approval

    - Explosion proofed types and Safety certified types (SIL certified)

  • Absolute encoder
    Absolute encoder for position control for the whole steel process as well as EOT steel plant cranes....

  • The absolute encoders made by Johannes Huebner Giessen are mechanically and electrically robust and reliable unit for use under the harshest ambient conditions. The encoders are providing position feedback and can also supply an incremental speed signal as option. 
    The absolute encoders are based on the latest photoelectrical scanning technology with highest accuracy on the market and are available in single turn or multi turn configuration. It supplies several output protocols such as ProfiBus, SSI, Parallel, EtherCAT and further more. The pulse-disk scanner consists of an LED and a specially designed optical system, with substantial separation between the disk and the scanning unit. Because the electronics board is encapsulated, the encoder are not susceptible to mechanical effects such as higher shock and vibration, loads and thermal expansion.

  • Magnetic encoder
    Magnetic encoder systems from Hübner Giessen for many application at the steel process. Flexible design for various shaft diameters. Solutions for applications with no free shaft end....

  • Magnetic encoders from Huebner Giessen are bearing less encoder systems for speed and position feedback from rotating parts. The high-precision signal through special multiple scanning system is providing a reliable signal feedback even in the harshest environment e.g. in cold- or hot rolling mill process. The modular concept enables customized solutions for shaft diameters up to 60”. The system consist of two parts. The pulse wheel and the scanning head. An extra-slim design makes installations possible even for areas with extremely restricted installation spaces.
    Product details:
    - Split pulse wheel available – ideal for retrofit projects
