The encoders above are available with several analoge or digital output signals:

  • 5 VDC or 1-30VDC with TTL/RS422
  • 11-30 VDC with HTL Push-Pull
  • 5VDC or 11-30VDC with Sin/Cos 1 Vpp
  • Other signal types on request

The Bei Sensors Functional Safety line will help you to achieve SIL 1, SIL 2 and even SIL 3, or the comparable PL (B,C,D or E) levels. Further expanding their FS possibilities, Bei Sensors offers specific functional safety modules. These assist in reaching the different FS certifications, without the need for a complete control system overhaul. This is achieved by adding different safety circuits in your current operating system (Motors/Sensors/PLC/Drives).
