Auto-Floating Blanking

The operating mode auto-floating blanking is required for applications with moving objects that continuously move through and even exit the safety field (e. g. skid carriers and forklifts), thus interrupting specific safety light curtain beams in a defined fashion. Only intrusions into the safety field at any other point within the safety light curtain cause the safety output to switch and stop hazardous motion. As opposed to floating blanking, not only is the geometry of the object significant for correct functioning, but rather entry of the object into the safety field as well. The period of time during which the object is permitted to dwell within the safety field is limited.
