RIK 4 vac

The LIK Series was especially designed for applications with limited installation space. The very flat and light design of the encoder enables the user a wide range of applications.

  • Special vaccum version of the RIK 4 with EPIFLEX sensor module (1-field scanning)
  • Components are vacuum compatible up to 10 E-9 mbar (UHV) athmospheric pressure
  • Heating cycles of 12 h at 150 °C possible
  • 1 Vpp or RS 422 output signal
  • Up to 100-times signal interpolation
  • Measuring steps up to 0.135 arc seconds
  • Rotational speed up to 22,200 rpm (with 1 Vpp)
  • Minimal mass moment of inertia of the aluminium grating disk, therefore applicable for high angular accelerations
  • Up to 24,000 increments on a grating disk (RS 192)

Kit R4 vac

The Kit R4 Series was especially designed for applications with especially customized requirements. These systems are not only extremely small, they are also particularly configurable. Your ideas won't be hardly limited with this series.

  • Special vaccum version of the Kit R4 with EPIFLEX sensor module (1-field scanning)
  • Components are vacuum compatible up to 10 E-6 mbar (HV) athmospheric pressure
  • Heating cycles of 12 h at 150 °C possible
  • Integration even in smallest applications (motors, piezo stages, etc.)
  • 1 Vpp or RS 422 output signal
  • Up to 100-times signal interpolation
  • Smallest measuring step 0,135 arc seconds
  • Rotational speed up to 22,200 rpm (with 1 Vpp)

Graduated Disks

Aluminum Graduated Disks

Suitable to our rotary encoders we offer aluminium graduated disks in different sizes and numbers of lines. Our team likes to support you in the conception and planning of your application. We offer the graduated disk assembly on your customized hub and measurement as a service, for example. If required we also take over the manufacturing of the hub.

Glass Graduated Disks

For applications with special environmental conditions (e.g. magnetic fields, heat sources, vacuum, etc.) we also offer graduated disks made of glass.
