METAL-SHEET DOUBLE-FEED DETECTION

From ultra-thin lead frames to iron sheets…
Double feed detection of various metal sheets

Detecting overlap of washers

GD-3 detects an overlap of small components such as washers.

Detecting double feeds of lead frames

The high precision sensor head GD-10 does not miss double feeds of lead frames even if they are very thin and highly perforated.

Detecting double feeds of sheet metal

The long sensing range sensor head GD-20 allows the object thickness to be as much as 10 mm 0.394 in. Hence, various objects can be detected.

Detecting seam of hoop material

Even a minute difference in thickness can be detected.

Detecting double feeds of aluminum foils

GD-10 can detect double feeds of thin aluminum foils which are several tens of micrometer thick.

Detecting missing tablet package in box

GD-20 can check if each box contains a given number of aluminum tablet packages. Since GD-20 has a sensing range of up to 70 mm 2.756 in, thick boxes can pass through the sensor heads.
