Heliostat – tracking in concentrated solar power plants

In order to align and adjust the mirrors to best track the sunlight, the heliostat is guided by encoder systems that adjust and identify the exact x and y position of the mirror. SICK manufactures a range of absolute and incremental encoders, for example the AFS60 absolute singleturn encoder that provides very high accuracy, even at extreme ambient temperatures.

  • Following product families can be used
    • High-resolution absolute encoder with up to 30 bits (AFM60) or 18 bits (AFS60)
    • Face mount flange, servo flange, blind hollow shaft or through hollow shaft
    • SSI, SSI + incremental or SSI + sin/cos interface
    • Resolution, offset, etc. can be programmed (depending on the type)
    • Connectivity: M12 or M23 male connector or cable connection
    • Enclosure rating: IP67 (housing), IP65 (shaft)
    • Operating temperature: –40 °C ... +100 °C (depending on the type)
