Sku: SIK-WH5850
Absolute rotary encoder with hollow shaft and industrial Ethernet
Product Information
The absolute optical multiturn rotary encoder WH5850 is particularly high-resolution and designed for time-critical applications. Thanks to the large selection of Industrial Ethernet interfaces, such as PROFINET (also with PROFIdrive profile), EtherNet/IP and EtherCAT, as well as short reaction times and 100% magnetic insensitivity, it is ideally suited for use in drive technology, bearing technology and factory automation. Thanks to the support of the latest PROFINET, EtherNet/IP and EtherCAT functions, it offers easy integration and optimum system availability!

Industry 4.0
In most cases, data exchange with the absolute rotary encoder is limited to the exchange of process data. In addition to the process data, intelligent industrial Ethernet rotary encoders provide additional information that can be evaluated for condition monitoring up to predictive maintenance:
| Process Data | Smart Value | Smart Function |
|---|---|---|
| Actual position | Temperature | Condition monitoring |
| Speed | Limit speed | Application overload |
| Operation hours counter | Operating time | |
| Electronic type label | Asset management | |
