Metal-sheet Double-feed Detector GD


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

Features

Double metal sheets detected

The high-end GD sensing technology detects double feeds of any metal sheet 0.01 mm0.0004 in, or more, thick.

Double metal sheets detected

Easy sensitivity setting with actual samples

Optimum sensitivity setting is easy by using the teaching function with actual samples.

Easy sensitivity setting with actual samples

Small object detection sensor head [GD-3]

This is an extremely small sensor head, only ø3.8 x 15 mm ø0.150 x 0.591 in, suitable for detecting small components.

Small object detection sensor head [GD-3]

High precision sensor head [GD-10]

It is suitable for high precision detection of double feeds of lead frames or thin metal sheets.

Long sensing range sensor head [GD-20]

It achieves a long sensing range of 70 mm 2.756 in. Further, it employs a robust metal case with IP67 protection to withstand harsh environment.

Seven LEDs indicate the sensing level

The optimum sensing point can be confirmed at a glance as seven LEDs indicate the sensing level.

Suitable for flexible manufacturing

Since sensitivities of eight channels can be stored, product changeover is smooth and easy. Select channel number by the "Channel shift key" on the operation panel or by using external channel select inputs. Further, since GD-C2 is equipped with RS-232C communication function, the sensitivity values can be stored in a personal computer, etc., and fed into the controller as per requirement.

Suitable for flexible manufacturing

Two-sheet threshold level shift function

The two-sheet threshold level set by teaching can be shifted in nine steps to suit the detection conditions. This enables very stable detection.

External initialization

Teaching is possible by external devices, such as, PLC, etc. This enhances productivity by machine automation.

Applications

Detecting overlap of washers
Detecting overlap of washers

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

Detecting double feeds of lead frames
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

Even a minute difference in thickness can be detected.

Detecting double feeds of aluminum foils
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
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.
