Optical pinhole inspection unit


The C12760 is a versatile pinhole inspection unit designed for rechargeable battery separators and can detect pinholes in translucent materials that allow light to pass through and so cannot be detected with other units of our lineup. The C12760 is compatible with high-speed conveyor lines moving at a maximum speed of 600 meters per minute and is usable on various workpiece widths by arranging them in multiple inspection units.


  • Minimum detectable pinhole size : 10 μm
  • Detection width (per unit) : 50.8 mm
  • Maximum detection speed : 600 m/min
