SLB400 Safety Light Barriers
Key Features

  • Connection of up to four safety light barrier pairs
  • very small design
  • can be coded (up to four systems do not interfere with each other)
  • start-up test
  • different operation modes selectable: with or without start/restart interlock with or without contactor monitoring
  • integrated pollution monitoring
  • switching condition and fault indication
  • signalling outputs for external displays
  • meets the requirements of the highest category (self-monitoring, ESPE-S) 
  • EC-test type certificate according to the latest standards and directives (IEC 61496)
Application

  • The series SLB 400 is suitable for applications to Control Category 4 (EN 954-1) and for sensing ranges up to  15 m. Typical application fields are e.g. the safe guarding of:
  • perimeter guarding
  • operating range of industrial robots
  • palletisors
  • rack equipment and devices
  • stacking systems
  • winding and unwinding machines
  • printing and paper processing machines
  • machines of the chemical, rubber and plastic industry

The complete safety light barrier system consists of:

  • the safety monitoring module SLB 400- C10-1R
  • up to four through-beam safety light barrier pairs type SLB 400-E/R50-21P The safety monitoring module in combination with the safety light barriers are designed as a self monitoring device according to IEC 61496, type 4.
