Numerik Jena: Standard Incremental Rotary Encoder (RIK 4 Series)

Our exposed rotary encoders consist of a scanning head and a grating disk. These measuring systems are basically characterized by the following main features:

  • Non-contact optical scanning of the ratchet disk by the measuring head, thereby no mechanical retroactive effect on the shaft

  • No mechanical coupling between rotary axis and measuring system, thereby no transmission errors

  • Low space requirement

  • High resolution up to 0.135”

  • Large mounting tolerances

  • Integrated compensation of the measurement signals’ offset- and amplitude fluctuations


Typical fields of application:

  • Production and inspection machines for the semiconductor industry

  • Rotary and Pivot axes

  • Pick-and-Place positioning systems

  • Controlled drives

  • Direct drives (torque motors)

  • Handling technology

  • Positioning and measuring systems for medical engineering

  • Robots


RIK 4 Features:

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.

  • With EPIFLEX sensor module (1-field scanning)

  • Individually configurable

  • 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 aluminum grating disk, therefore applicable for high angular accelerations

  • Up to 24,000 increments on a grating disk (RS 192)

  • Special vacuum version available


Scale Types:

Aluminum Grating Disks

Suitable to our rotary encoders we offer aluminum grating 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 grating disks assembly on your customized hub and the measurement as a service, for example. If required we also take over the manufacturing of the hub.


Glass
Grating Disks

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