Absolute encoder WV5850

Absolute rotary encoder with solid shaft and industrial Ethernet

open expert video

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 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 functions, it offers easy integration and optimum system availability!

Profile WV5850:

Absolute optical encoder
High-precision and up to 19 bit single-turn resolution
PROFINET IO, EtherNet/IP interfaces
Robust bearing construction as well as high shock and vibration resistance
100% magnetic insensitivity
Fast commissioning and high system availability
Industry 4.0 ready

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
