Get the most out of your machines

Absolute Profinet encoders of the ACURO series are offered by Hengstler for those of you looking to get the most out of your machines, expecting to use latest technology, who want to install an encoder and forget about it and are new to implementing Profinet. You can use one of the top absolute encoders with any Profinet system to greatly simplify the process of device design and enabling reliable communication. The latter is especially important in complex installations and multi-purpose machines.

There are two sub-series of ACURO encoders with the additional Profinet interface available, the ACURO AC58 and ACURO AC61. They also feature standard SSI, BiSS, EtherCAT, Profibus, CANopen, CANlayer2, DeviceNet, Interbus and SUCOnet interfaces.
