The opto-electronic safety edge OPTOEDGE is comprised of an infrared
safety light barrier enclosed in a hollow rubber profile. When the
hollow rubber profile is deformed, the optical channel is inter-rupted,
causing a dynamic safety signal to fail. This is detected by the
control unit which interrupts the enable circuit. The potentially
hazardous movement is halted.The OSE does not require direct
visual contact between transmitter and receiver. Since the infrared
light beam is reflected by the surface of the rubber profile, operation
of the safety edge is not affected by minor bending due, for instance,
to wind loads. Major bending or compression of the optical channel, on
the other hand, attenuate the light so strongly that the safety edge
switches off reliably.
