●Non-contact detection applies no stress or impact to workpiece
●Detecting tiny pinholes with high accuracy
Using a high-sensitivity photomultiplier tube allows detecting tiny pinholes of a minimum of 2 μm in
diameter at a maximum rate of 30 meters per minute, which has not been possible to detect by image sensor image analysis.
●Pinhole determination based on threshold
Detection sensitivity and pinhole pass/fail threshold are adjustable to any value from front panel.
●Self-diagnosis function
Checks detector operation to ensure high reliability of inspection results
●Safeguard circuit to protect the unit from excessive light
Includes a safeguard circuit that minimizes damage to the detector even when excessive light enters the unit.
●Two types with different light source positions are available to match your application
The light source emits light onto the inspection target and the detection unit on the opposite side detects any light leakage from pinholes.

NOTE:
①Detection pinhole size depends on light intensity and installation environment.
Supplied: Control input / output connector, light source connection cable and pinhole sample plate (pinhole size 2 μm)
◎ Aluminum laminate films
◎ Metal foils
◎ Aluminum blister packaging materials
The inspection object should be positioned as close to the detection unit as possible to boost detection performance and prevent fluctuating ambient light from entering the detectors.
For example, when inspecting aluminum blister packaging materials, the molded convex side should preferably face the light source unit and the concave side face the detection unit.
