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. LASER SENSORS PHOTOELECTRIC SENSORS MICRO PHOTOELECTRIC SENSORS AREA SENSORS GD-3 GD-10 Detecting seam of hoop material Even a minute difference in thickness can be detected. SAFETY LIGHT CURTAINS / SAFETY COMPONENTS PRESSURE / FLOW SENSORS INDUCTIVE PROXIMITY SENSORS GD-20 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. PARTICULAR USE SENSORS SENSOR OPTIONS SIMPLE WIRE-SAVING UNITS WIRE-SAVING SYSTEMS MEASUREMENT SENSORS GD-3 GD-10 Tablet packages GD-20 LASER MARKERS PLC FUNCTIONS HUMAN MACHINE INTERFACES Seven LEDs indicate the sensing level Suitable for flexible manufacturing The optimum sensing point can be confirmed at a glance as seven LEDs indicate the sensing level. 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.

If real objects differ from teaching samples in size or in characteristics, or the detecting condition deviates, an error may occur. Please note that magnetic metals or metals with low magnetic permeability such as steel especially have a strong tendency. • In situations when magnets are in close proximity such as during electromagnet conveyance, this causes malfunctions due to electromagnetic disorder. • When conducting minute detections, favorable sensing conditions are obtained only after having elapsed 60 min. after the initial introduction of the power supply. Metal-sheet Double-feed Detector DIMENSIONS (Unit: mm in) GD-3 GD SERIES 1142 The CAD data can be downloaded from our website.
