Recording of the angular position and revolutions by means of Hall sensors - multiturn version with absolute multiturn transmission for up to 4096 revolutions - data output plus parameterisation and diagnosis via PROFINET. Robust housing manufactured from seawater-resistant aluminium or stainless steel - stainless steel shaft - ball bearing with radial shaft seal-sensor circuit consisting of ASIC with Hall elements - electrical connection via M12 connector or cable outlet. The Profinet interface according to IEC 61158 / 61784 or PNO specifications order No. 2.712 and 2.722, version 2.2, is integrated into the model series TRT absolute encoders. Real time classes 1 - 3 are supported, i.e. Real Time (RT) and Isochronous Real Time (IRT) plus the requirements of conformance class C. Setting the address, baud rate or terminating resistances is not necessary. A name, which is stored in the absolute encoder's non-volatile memory, is assigned via the PROFINET controller to address the device.
