842e cm integrated motion on ethernet ip encoder

Bulletin 842E-CM Integrated Motion on EtherNet/IP™ Absolute Encoders are designed for motion control applications that require feedback-only axes. These encoders support the standard motion instruction set in the Studio 5000 Logix Designer™ application. By providing auxiliary feedback directly through an EtherNet/IP network, these encoders eliminate the need for point-to-point wiring. You can use them in a variety of network topologies such as linear, ring, or star. These encoders leverage CIP Sync, a time synchronization extension that is fully compliant with IEEE 1588. 

  • Provides EtherNet/IP Interface that is compliant with IEEE 1588
  • Offers high resolution feedback through single-turn and multi-turn options 
  • Supports Ethernet topologies including linear, ring and star 
  • Provides easy IP addressing 
  • IP67 protection class 
  • Available in solid and hollow shafts
