The DAF100 Adjustable Stroke Detect-A-Finger® drop-probe device for riveters and welders reduces accidents at the point of operation where the operator’s fingers can enter. This device is an electric-air system that consists of two main components: the drop-probe assembly and the control box. The standard unit can provide a stroke of up to 4-inches and can be mounted on the left or right side of the machine. Location of the DAF100 should be determined by the availability of the mounting surface, the size or shape of the workpiece, and the throat depth of the machine.
The drop-probe assembly functions by allowing the sensing probe to drop around the point-of-operation hazard prior to each intended machine cycle. If the sensing probe encounters the operator’s fingers and fails to drop to a preset position, the machine cycle will not be initiated. If there are no obstructions to prevent the sensing probe from dropping, then the control unit will allow the machine to cycle when the sensing probe reaches the preset position.
