Absolute Encoders on 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.
