Description

Versatile absolute rotary encoders

The rugged singleturn absolute rotary encoders AS…40 and AS…H 40 can be deployed in a wide variety of applications to detect positions in steel and rolling mills, in mining operations as well as in ports and crane systems. The absolute rotary encoders supply precise information about the position of the shaft. The encoders are installed for position measuring as well as positioning tasks. Thanks in particular to the extremely rugged foot construction it is possible to easily attach additional encoders to the second shaft end.
