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
