Numerik Jena: Compact Incremental Rotary Encoder (ULTHEMIUS 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


ULTHEMIUS Features:

ULTHEMIUS is a sealed micro shaft encoder with an especially small diameter of only 16.1 mm. Due to his special components this encoder is a light-weight and can be mounted to a motor shaft.

  • Very good signal quality due to transmitted light technology

  • Measuring steps up to 16.2 arc seconds

  • Rotational speed up to 6.000 rpm

  • High counting frequency up to 16 MHz

  • 1 Vpp or RS 422 output signal

  • Minimal mass moment of inertia of the plastic grating disk, therefore applicable for high angular accelerations

  • Overall weight of 12g
