ABB JOKAB SAFETY has introduced Focus II Light Curtains and Light Grids, a model that can be used for many applications, eliminating the need to stock multiple versions for varying machine safety requirements. The product consist of two optical units, a transmitter and a receiver, which are continuously scanned, quickly detecting any objects that break the optical barrier. Five LEDs in the receiver and the two in the transmitter show the status of the light curtain. If any light beam is interrupted, the machine movement is stopped by the outputs from the light curtain. The reaction time for the device varies from 14ms to 45ms, depending on the number of beams in the light curtain or grid. Both curtains and grids have received all necessary national and international safety approvals.
