Hard Disk Detection

To detect whether shiny disks are properly seated


Because disk surfaces are shiny, many sensors have difficulty detecting whether a hard disk is properly seated in a hard drive.

The divergent-beam MINI-BEAM Expert sensor is installed above a conveyor transporting hard disks. The sensor is programmed to recognize a predetermined amount of returned light. When the sensing beam is directed onto a perpendicular specular surface, such as a properly seated hard disk, more light is returned to the receiver.

The MINI-BEAM sensor pair triggers the MINI-BEAM Expert.
