Singleturn absolute encoder with a solid shaft 

Absolute encoders from Johannes Huebner Giessen are designed for operations in extreme operating conditions: They have a robust, thick-walled aluminium casing and large ball bearings with a high dynamic load rating; the encapsulated interior space remains sealed even when the generously dimensioned terminal box is open. All screwed connections are vibration resistant. The singleturn version of the absolute encoder with a solid shaft AS... 40 is compatible with all customary interfaces, such as PROFIBUS DP, PROFINET IO, DeviceNet, EtherCAT, SSI and parallel interfaces and can be supplied with an incremental output, if required. The singleturn version offers a maximum resolution up to 16 bit (steps per revolution: 65536). A second shaft end is available on request.
