Description

Siko AV58M Absolute Encoder: Metal housing with solid shaft. The AV58M rotary encoder with teach-in function is a magnetic absolute value encoder with analog output. The user himself can set the rotary encoder’s desired measurement range via two buttons on the rear as well as two external inputs. The device features batteryless multi-turn technology.

Rotary encoders based on the absolute measuring method

Absolute rotary encoders also called Absolute value encoders, are encoders that unambiguously encode every shaft position and display it as a position value. Thus, absolute value encoders are able to deliver unambiguous position values from the moment they are started. For instance, an absolute rotary pulse encoder detects its position exactly also after restart even when it has changed in the de-energized state. Therefore, with the absolute measuring method compared to incremental rotary encoders, there is no need for time-consuming reference travels after the machine start or after the loss of supply voltage.
