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), on request: RS422, RS422 (adressable), RS232 or CAN BASIC ELGO, in preparation: BISS-C
  • Additional incremental signals for highly dynamic drives
  • Non-contact, wear-free measuring principle
