Rotary shaft seals - Import export

Sealing solutions for rotary shaft applications

Recording of the angular position and revolutions by means of Hall sensors - 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 and 3 are supported, i.e. Real Time (RT) and Isochronous Real Time (IRT) plus the requirements of conformance class C. To achieve the SIL2 level, the TRT/S3 contains addtitional internal monitoring mechanisms as well as safe communication via PROFIsafe. The PROFIsafe protocol is implemented according to the PROFIisafe Profile for Safety Technologie version 2.4 (PNO Order No. 3.192)

Robust case with wall thickness of 5 mm either in seawater resistant aluminum or in stainless steel - shaft in stainless steel - rotating components with permanent magnet in front chamber - electronic circuit with ASiC and Hall elements and interface components fitted within main chamber, separated from rotating components by a metallic wall - integrated absolute multiturn gearbox for the acquisition of revolutions - optional potting against water jets (IP 69K) - electrical connections via round plug M12x1 or lead exit.

Recording of the angular position and revolutions by mens of Hall sensors - multiturn version with absolute transmission for up to 4096 revolutions - data output plus parameterisation and diagnosis via Profibus-DP. Robust housing manufactured from seawater-proof aluminium or stainless steel - stainless steel shaft - ball bearing with radial shaft seal - sensor circuit consisting of ASIC with Hall elements - electrical connections via the connecting cap with threaded cable connections. The absolute encoders are designed for direct connection to the PROFIBUS-DP. The interface is implemented with the SPC3 Siemens PROFIBUS controller. The protocol corresponds to DP-Slave Class 2 functionality in accordance with Profibus profile for encoders, No. 3.062, and is described in detail in the TRD 12770 user manual. The TRD is mechanicallly and electrically compatible with the electro-optical encoder CRD.
