EMAX-RO Absolute Rotary Encoder (SSI / CANopen) Bearingless, wear-free and high-resolution for rotative applications
EMAX-RO features a very short design, so it's perfectly suited for use in cramped installation conditions and on direct drives.
- Magnetic single-turn absolute encorder
- Direct measurement on motor shaft or axis
- High resolution 16,000 measuring steps / revolution
- Diverse interfaces available: SSI or CANopen (standard), BISS-C, on request: RS422, RS422 (adressable), RS232 or CAN BASIC ELGO
- Additional incremental signals for highly dynamic drives
- Non-contact, wear-free measuring principle
