Safety Light curtains BLCT

Properties

  • Integrated control-unit with contactor control and restart can be programmed without a PC
  • Contactor/valves directly connectablly, switching capacity 0,5A/24V
  • Smallest safety distances by short response times 4 ms to 29 ms, depending of the protection high
  • Finger and hand protection with up to 5m protective width(resolution 14 mm and 30 mm)
  • Protection heights from 100mm to 1500 mm in steps of 100 mm
  • Microcontroller monitoring of the safety functions (self-monitored)
  • Semiconductor outputs with short-circuit and crossconnection monitoring
  • Integrated self-diagnosis with a fault indication by 7-digit display
  • Optional safety switchgears permit muting and clocked operation
  • Direct connection via M12 connector
  • Compact design 25 x 35 mm w/ flexible fastening by tenon blocks and protection category IP 65

The light curtain correspond to the highest safety regulations:
Safety Integrity Level SIL 3 (IEC 61508) 
Performance Level PL e (ISO 13849-1)
Safety category cat. 4 (EN 954-1)
