Specifications and Drawings

Numerik Jena: Vacuum Incremental Rotary Encoder (RIK 4 VAC & KIT R4 VAC)

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 VAC 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.

Special vacuum version of the RIK 4 with EPIFLEX sensor module (1-field scanning)
Components are vacuum compatible up to 10 E-9 mbar (UHV) atmospheric 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 aluminum grating disk, therefore applicable for high angular accelerations
Up to 24,000 increments on a grating disk (RS 192)

KIT R4 VAC Features:

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 vacuum version of the Kit R4 with EPIFLEX sensor module (1-field scanning)
Components are vacuum compatible up to 10 E-6 mbar (UHV) atmospheric 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)

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.
