Safety Light Curtains
Safety Light curtains are electro sensitive devices using one or more light beams, emitted by an Emitter and received by a Receiver, to create an intangible controlled area.
SAFETY LEVEL
Defines the self-monitoring and safety principles contained in the device; it must be chosen as a function of the risk level characterising the machine.
PROTECTED HEIGHT
This is the height protected by the light curtain. If it is positioned horizontally, this value shows the depth of the protected zone.
RANGE
This is the maximum working distance that may exist between the emitter and the receiver.
RESPONSE TIME
This is the time it takes for the safety light curtain to transmit the alarm signal from the time the protected zone is interrupted.
LIGHT CURTAIN RESOLUTION
The resolution of a light curtain is the minimum size of an object that, placed into the controlled area, will obscure the controlled zone and hence stop the hazardous movement of the machine.
