Absolute HeavyDuty encoders deliver the absolute angular position of shafts, for example rotor shafts in electric motor or cable drums at container cranes. Singleturn encoders acquire the absolute position within one turn of the encoder shaft, while multiturn encoders additionally provide the number of turns completed by the encoder shaft. Usually, referencing of absolute encoder shaft position is carried out during commissioning. In this way, the need for reference travel after power-on is eliminated.

In addition to the absolute position output via serial digital interfaces such as SSI or fieldbuses, absolute HeavyDuty encoders still allow the output of the incremental position, for example, as HTL / TTL signals, for simple processing in speed controllers with incremental input. Individual HeavyDuty encoder versions are also available with speed switches, which report a too high or too low speed via a switch output.

Absolute HeavyDuty encoders are designed for maximum robustness and durability, with enormous mechanical reserves to ensure reliable performance even in the harshest environments:

  • Steelworks and rolling mills
  • Port installations and crane technology
  • Hoists and lifting platforms
  • Underground and open pit mining
  • Materials handling equipment
  • Large drives and generators
  • Wind turbines
