Numerik Jena: Sealed Linear Incremental Encoder (LIS 73-1 Series)
Our exposed linear encoders consist of a scanning head and a scale tape. These measuring systems are basically characterized by the following main features:
The users slide system takes over the steering between the scanning head and the scale tape
Non-contact optical scanning of the scale tape by the scanning head, thereby no mechanical retroactive effect on the slide system
Low space requirement and uncomplicated assembly
High traversing speed up to 10 m/s
Signal interpolation up to 100 times integrated in the measuring head or the connector and high resolution up to 50 nm
Large mounting tolerances
Automatic signal adjustment after mounting possible
High scale accuracy up to ±1 µm
High interpolation accuracy and low sensibility to contamination due to dynamic offset- and amplitude control
Reference signals with increment-precise repetitive accuracy independent to the reference marks’ approach
Defined thermal behaviour supported by our DOUBLEFLEX scale tapes
Typical fields of application:
Production and inspection machines for the semiconductor industry
Linear units and linear drives
Coordinate tables
Measuring machines and measuring microscopes
Robotics
Precision devices in reprography
Precise machining
Positioning and measuring devices in medical technology
LIS 73-1 Features:
Sealed measuring system based on our approved sensor technology with housing version 1
The steering between the measuring head and the measuring unit happens measuring system-internally
The measuring systems components are protected from contamination by an aluminum capsule and elastic sealing
Tilting or deviations of the driver perpendicular to the direction of measurement are balanced within ranges of large tolerance without measuring errors
