843E Absolute Encoders with EtherNet/IP
843ES CIP Safety over EtherNet/IP Absolute Encoders
843E Absolute Encoders with EtherNet/IP
Our EtherNet/IP™ Absolute Encoders are designed with an embedded EtherNet/IP switch and dual Ethernet ports to support linear networks and Device Level Ring topologies. By providing auxiliary feedback directly through an EtherNet/IP network, these encoders eliminate the need for point-to-point wiring. These encoders are designed for high performance and reliability in harsh industrial environments. Our encoder offerings include models that brings in the encoder as a feedback only axis for machine applications using integrated motion on EtherNet/IP. We also offer models designed for safety applications that require speed, direction, or position monitoring safety functions.

In Episode 3 of ROK Talk, Rob and Nathan have two guests Linxi Gao, Product Manager, and Jon Riemer, Commercial Project Engineer for Safety Systems. Linxi gives an overview of Safety Encoder features and application examples, while Jon talks about selection, and the differences between drive- and controller-based applications.
