Edge hold mode ignores slow distance changes and detects only sudden changes in height. The GV Series detects the change of the distance so the detection is not affected by the traveling speed of the workpieces.
With a workpiece that has a dual reflection
Some workpieces reflect the light from both top and bottom
surfaces, making detection difficult.
The surface detection mode ignores all other reflections and detects only the nearest surface.
When the target comes too close to the sensor head
Even when the target comes too close to the sensor head and does not enter the detecting area, this function keeps the previous ON/OFF state.
