  • Extremely rugged, tried-and-tested absolute multiturn encoder with a resolution of up to 26 bits
  • Mechanical interface: through hollow shaft with shallow installation depth
  • Zero-set and preset functions via hardware or software
  • No battery required
  • Electrical interface: SSI with gray or binary code type
  • Electronically adjustable, configurable resolution
  • Magnetic scanning
  • Your benefits

  • Fewer variants are required since one freely programmable encoder offers all singleturn and multiturn resolutions
  • Easy setup due to various electrical connection adapters (cable, M23)
  • Application flexibility due to easily interchangeable collets for the blind hollow shaft
  • Quick commissioning using the zero set/preset function either at the press of the button on the device or via software
  • Increased productivity due to highly reliable shock and vibration resistance
  • Worldwide availability and service ensure quick and reliable customer service
