The optical safety SIL CL 3 absolute rotary encoder by Posital delivers digitally the sensed position values via the integrated CANopen interface according to CANopen Safety protocol CiA 304 and CANopen standard  CiA 301.

The main features are

  • Certified by TUV Rheinland, Number: 01/205/0701/10
  • Safety integrity level (EN 62061): SIL CL 3
  • PFDav (EN 62061): 27% according to SIL 3
  • Performance Level (EN ISO 13849-1): PL e
  • Safety category (EN ISO 13849-1): Cat 4
  • CANopen Safety communication profile acc. to EN 50325-5
  • Simultaneous operation of CANopen protocol according to CiA 301
  • Transmission of "Safety Position Value", no position validation in PLC necessary
  • More cost efficient than redundant realization with two standard encoders and coverage of common failure
  • Housing 58 mm in diameter
  • Shaft: 6 mm or 10 mm in diameter, hollow shaft: 15 mm
  • High protection degree up to IP66
  • Rresolution / revolution up to 16 bit (non safety)
  • Total resolution: up to 30 bit, 16 bit steps at 16 384 revolutions (gearing, no battery back up)
  • Code: binary
  • Galvanically isolation of bus interface
  • Diagnostic LEDs in connection cap
  • Standard version with connection cap or connector

Programmable parameters
