Application:
Optoelectronic safety devices are used to protect access to hazardous points or hazardous areas.
SLB range safety light barriers are utilised as entry guards to dangerous areas. These protection devices operating without physical contact achieve Control Category 2 or 4 to ISO 13849-1 in combination with SLB 200-C or SLB 400-C safety monitoring modules.
Design and mode of operation:
On the SLB/SLC/SLG ranges of optoelectronic safety devices, the emitter and receiver are fitted in two separate enclosures. An invisible infra-red signal is sent from the emitter and this is picked up by the lens system of the receiver and evaluated either by an integral or external safety monitoring module. If the light beam is interrupted, the secure outputs are switched.
All of the optoelectronic safety devices listed here are maintenance-free and are characterised by simple fitting and adjustment.
