Fiber sensor used to measure mobile phone speaker dimensions. Use of fiber with led light eliminates the need for more costly laser.
In order to be installed closely, a compact narrow-beam sensor is required. But a laser sensor is too big and expensive.
Solution
If we try to focus on the tip when the tip is not present, the beam spot will hit the land (end side in copper pattern) or soldering part and reflect more light. Purposely shifting the focus of the spot to achieve a stable detection.
A fiber sensor is applicable to small jigs accompanying small targets. When a super fine spot lens FX-MR6 is attached, detection of super fine boss (0.6×0.6mm) is also possible. Detection is done using safe LED light source instead of laser. Saves cost in comparison to using a laser sensor.
