The CANopen interface option has been added to the previously announced SSI, Ethernet/IP, Ethercat, Powerlink, Profbus DP, and Profinet interfaces of the Ixarc absolute rotary encoders. The precision rotary encoders, first introduced in 2013, provided a step forward in encoder technology: with improved magnetic field measurement sensors and signal processing techniques, Posital was able to offer devices with accuracy and dynamic response characteristics. Single- and multi-turn models are available. For multi-turn versions, the rotation counter is self-powered, with no need for backup batteries.

The Ixarc encoders with the CANopen communications interface are a suitable choice for applications in vehicles, mobile machinery, cranes, lifts, and offshore equipment. The communication interface features the autobit function, so these encoders can be directly connected to a CANopen network without the need to manually set transmission speeds. Diagnostic LEDs show the device status. A variety of connection options are available, including cables of various lengths and radially or axially oriented M12 or M23 connectors. Housings with bus-in/bus-out connectors are available for applications where it is convenient to connect several devices in series (daisy chain).
