Singleturn absolute encoder with hollow shaft

Rugged, thick-walled aluminium casing, large ball bearings with high dynamic load rating and an encapsulated interior space that remains sealed even when the terminal box is open – absolute encoders from Johannes Huebner Giessen are designed for reliability even in extremely harsh conditions. The encoders are very vibration and shock resistant by design. The singleturn version of the absolute encoder with a hollow shaft AS...H 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. The long torque bracket arm facilitates a higher signal quality.
