Rotary Encoders For Space Applications -icon

Space

Typical Characteristics

Netzer Precision Sensors is offering custom absolute rotary encoders for low-orbit & deep-space applications. Space high-resolution encoders are application-dedicated and the specifications and configuration are built in close cooperation with the customer. The space encoders are based on Netzer’s unique capacitive technology which provides high absolute accuracy with extremely high shock and vibration resistance.

Space encoders are offered in various configurations

  • Absolute analog output (Sine + Cosine in two or three channels)
  • Absolute digital encoders with a resolution of up to 19 bit
  • Combined configuration with separate analog and digital boards to be installed separately
  • Standard component or Mil / EEE / ESA standards. (RoHS Vs Non RoHS)
  • Rad hardened or Non-Rad hardened (45 -100 Krad)
  • Enclosed spindle configuration or “Two plates” contactless configuration

Space requirements capabilities:

Environmental testing

  • Shock – Up to 100 g 10 ms
  • Vibrations
  • Thermal cycles under vacuum (10־⁵ Torr)

Clean-environment components assembly (SMT)

Dedicated mechanical assembly – design, and production

Note: It should be taken into account that some specific configurations might be included under the export control regulations
