EMAX-HI Absolute Measuring System Magnetic high-resolution linear encoder for dynamic processes
High-resolution magnetic measuring system for absolute position measurement in dynamic applications. Ideally suited in linear drives.
- High-resolution - up to 1 µm
- Operation speed up to 10 m/s
- For measuring lengths up to 8 m
- Standard interfaces: SSI, CANopen (DS406)
on request: RS422, CAN BASIC ELGO or BISS-C - Additional incremental square-wave signals (A, B) or analog signal output Sin/Cos (1 Vss) in real-time for highly dynamic control (option)
- High safety during installation and operation by visual (LED) and signal output error message in case the max. allowable reading distance to scale is exceeded
- Typical applications: linear actuators, pick&place, medical technology
