Multiturn absolute encoder with a solid shaft

A multiturn version of the absolute encoder from Johannes Huebner Giessen is also available. The solid shaft version of the absolute encode AM... 40 is equipped with all customary interfaces, such as PROFIBUS DP, PROFINET IO, DeviceNet, EtherCAT, SSI or a parallel interface and can be supplied with an incremental output, if required. The multiturn version offers a maximum resolution up to 12 bit (number of revolutions: 4096). The absolute encoder AM... 40 multiturn is considered to be the standard version for heavy duty applications. It has a robust aluminium casing and large ball bearings with a high dynamic load rating; the interior space remains sealed even when the terminal box is open. Consequently, it is extremely vibration and shock resistant.
