Function
This multiturn absolute encoder with modern fast technology transmits a position value corresponding to the shaft setting via the SSI interface (Synchronous Serial Interface). The maximum resolution of the AHM58-H is maximum 65536 steps per revolution at 16384 revolutions.
In contrast to the AHM58 series the encoder does not have a microcontroller. Thus, it is a pure hardware encoder.
The control module sends a clock bundle to the absolute encoder to obtain position data. The rotary encoder then sends the position data synchronous to the cycles of the control module. It is possible to select the counting direction with the function input.
The absolute encoder is mounted directly onto the application shaft, without any coupling. Rotation of the absolute encoder is prevented by a torque rest.
The electrical connection is made by a 12-pin round plug connector. A version with a 1 m cable connector is also available.
