Digital CMOS Laser Sensor GV Series Up to 1 m Away Stable detection of metal targets Innovative solution for black targets
Conventional laser sensors have problems with... Metals Multiple reflection Metal workpieces scatter the laser light The correct valve cannot be detected due to multiple reflections Black rubber Low reflectance Black workpieces absorb light The detection is unstable due to the low reflectance 2
GV Series The latest light intensity control system reliably detects any colours. Best in the class Super wide dynamic range The advanced technology that responds to the 00,000 fold light intensity variation of workpieces. Dynamic range Accommodates a wide variation of light intensity reflected from a workpiece without degrading the accuracy of distance detection. Low intensity light for light workpieces High intensity light for dark workpieces The GV Series sets laser emitting time, power and gain optimally on a workpiece basis in real time. Targets with any colours can be reliably detected. Reflectance Super wide dynamic range ratio Power Adjustment range approximately 00,000 fold Item Laser power Light emitting time Gain Total Lowest detection range 1 1 1 1 Highest detection range* Two fold 3,92 fold 77 fold approximately 00,000 fold *When the response time is set at 50 ms. The DATUM function of the GV Series eliminates these problems!! Amplifier unit GV-21/21P GV-22/22P DATUM function Newly developed GV CMOS Stable detection and high-speed response The size per pixel of this CMOS is larger than that of the conventional one to receive a larger amount of light than before. This provides stable detection and high-speed response. Measurement principle The wider pixel size of the GV CMOS can receive more light than conventional CMOS imagers. The end result is: Stable detection High-speed response GV CMOS * A CMOS is a device with multiple light receiving elements aligned. 3

GV Series Sensor Head Four variations ranging from long-distance to high-accuracy detection. 45 mm 130 mm 450 mm Short-range type GV-H45/ NEW GV-H45L Middle-range type GV-H130/ NEW GV-H130L Long-range type GV-H450/ NEW GV-H450L Washable sensor head (head only) <IP7> Rugged, IP7-rated sensor heads can be put to the test in harsh environments. Ultra Long-range type GV-H1000/ NEW GV-H1000L 1000 mm Amplifier unit Wire-saving structure! Up to four units can be connected The power is supplied through the side connector when connecting expansion units. This saves two wires per unit (power +, -). 1 spot indicator This indicator tells you from the reflection whether the target is at the optimal position for detection. Make sure that the 1 spot indicator is lit when you perform the DATUM tuning. No multiple reflection Head side The GV Series amplifiers should not be connected with those of other models. Amplifier side Interference suppression function When expansion units are connected, up to two adjacent units can operate in close proximity to each other with no interference. Those two units should be set for the same response time.. This Interference suppression function is invalid for response times of 20 or 50 ms. There is a multiple reflection Head side Bar LED This bar LED shows you the detection state at a glance. Amplifier side Close Output ON Near the setting value Output ON Distant Output OFF Detection is understood at one view. External input (selectable) External shift input-------- The current value can be shifted to any value. Bank switching input----- The bank switches two setting values with each other. Timing input---------------- This input enables the output. Timer function (selectable) Off-delay, On-delay, One-shot On-delay/Off-delay, On-delay/One-shot 5
World s first DATUM Algorithm <Patent pending> When the DATUM (background, reference surface) tuning is performed, workpieces can be correctly detected. DATUM ALGORITHM Based on: Distance Received light pattern Detection image CONVEYOR <<< DATUM tuning >>> Easy tuning just by pressing the [SET] button with a target on a conveyor CMOS light received image CMOS Setting range Light waveform When performing the DATUM tuning (reference surface calibration) with a target on a conveyor (background), the values are set slightly above and slightly below the conveyor position. With no workpiece in place, the light waveform falls within this range. Output OFF <<< Detection example 1 >>> Flat workpiece Detection image CMOS light received image Setting range Light waveform The CMOS light receiving position changes The distance changes CONVEYOR CMOS The workpiece is judged as present Output ON <<< Detection example 2 >>> Rough workpiece Detection image CMOS light received image Setting range Light waveform 2 peaks appear on the waveform The light receiving pattern changes The workpiece is judged as present CONVEYOR CMOS Output ON <<< Detection example 3 >>> Round workpiece Detection image CMOS light received image Setting range The light is not reflected properly The distance changes The workpiece is judged as present CONVEYOR CMOS Output ON
GV Series Other convenient sensing algorithms <<< Edge hold mode >>><Patent pending> With an unstable background Normal state With an unstable background Edge Hold Detection of a workpiece on a conveyor Setting value Conveyor This operation mode ignores slow distance changes and detects only sudden changes in height (workpieces). The GV Series detects the change of the distance so the detection is not affected by the traveling speed of the workpieces. Setting value Position display Output (a) Distance detection mode ON (b) Edge hold mode ON (a) Distance detection mode Undetectable ON Does not turn ON (b) Edge hold mode Setting value The display is kept until OFF Change amount Output ON ON ON ON at the rising edge OFF at the falling edge Only the target is detected <<< Surface detection mode >>> With a workpiece that has a dual reflection Detecting cap height Translucent cover thickness A B Cover surface Cover inside A B CMOS Judgment A Cancellation B Some workpieces reflect the light from both top and bottom surfaces, making detection difficult. The surface detection mode ignores all other reflections and detects only the nearest surface. Translucent plastic container <<< Clamp function >>> When the target comes too close to the sensor head Setting value C B C Setting value B A CMOS Even when the target comes too close to the sensor head and does not enter the detecting area, this function keeps the previous ON/OFF state.
