3 The Keyence advantage... World's first Extremely high power Utilizes the world's first hybrid structure The SUPER RGB sensor was developed by a dramatic redesign of the sensor head structure to improve overall performance. The transmitter uses an optical fiber, which creates an incredibly uniform beam spot and helps reduce the size of the sensor head. The lightreceiving circuit is built into the sensor head, enhancing its detection ability and improving stability. First-in-its-class RGB light source for triple 16-bit calculation Three-color light source for accurate target recognition The SUPER RGB sensor incorporates three separate color LED s. The signal from each color is converted into 16-bit data in the receiver to enable color recognition. This ensures accurate detection regardless of target vibration. New sensor head cancels luster Virtually immune to luster, changes in shape/position, or inclination See page 4 for details. Internal structure Transmitter lens Receiver lens Operating principle of the RGB light source Green light source Blue light source Light-emitting fiber (The light-emitting element is located in the amplifier.) Receiver cable Light-receiving element Red light source Special half mirror The beams of three colors are brought into a straight line. World's first Automatic selection of 7 different light combinations (patent pending). See page 7 for details. Dual Digital display, amplifier CZ-V21 V22 Simple sensitivity adjustment One-touch calibration The SUPER RGB sensor can be calibrated with the push of a button. This simple approach eliminates variation between operators and ensures continuous, stable detection. 3

4 Choose the sensor head that is right for your application Adjustable spot, reflective type Adjustable beam spot Three beam spot sizes can be easily selected by adjusting the slide switch, allowing a wide range of targets to be inspected. Medium Large Small Long detecting range of 1.97" to 3.74" (50 to 95 mm) Detection is available within a range of 1.97" to 3.74" (50 to 95 mm). The sensor can be mounted at a long distance and is less affected by changes in target position. Distance vs. beam spot diameter (Typical) ø0.22" (ø5.5) (Large) ø0.18" (ø4.5) (Medium) ø0.12" (ø3) (Small) Beam spot diameter (inch mm) 0.35" " " " " " " " " " 2.36" 2.76" 3.15" 3.54" Large Medium Small Distance (inch mm) Luster-cancel, reflective type Less affected by shape, position, inclination, and surface luster (Patent-pending) Detection in an actual production line often fails due to variation in target conditions. In most cases, the failure results from ambient light reflecting off the shiny surface of a target. The incorporates a polarizing filter which cancels the reflection from the glossy section and only recognizes targets by their color components. The maintains accurate detection despite changing target conditions. Distance: 1.57" (40 mm) Beam spot diameter: ø0.18" (ø4.5 mm) What is luster? As the picture on the right shows, depending on the illumination some sections on a pepper s surface can appear white. Like human eyes, conventional sensors can not recognize the correct colors of such a target. 4

5 High resolution amplifier for triple 16-bit calculation RGB light source for diversified target recognition The SUPER RGB sensor enables stable detection by using a three-color light source. Advantage of the RGB light source 1 Accurate target recognition Single-color light source Three-color light source Almost no difference is recognized between certain colors, resulting in unstable detection. R G B R G B The received light is converted into a ratio of three colors, and the target is recognized by its color. This ensures accurate detection. Advantage of the RGB light source 2 Less affected by changes in target position Single-color light source Three-color light source R G B R G B When the target position changes, the received light changes according to the distance between the target and the sensor head, resulting in unstable detection. Even when the target position changes and the received light changes, the ratio of the three colors does not change. Stable detection is ensured. Dual digital display & Direct access Both the current value and set value are displayed simultaneously. Sensitivity and fine adjustment can also be done manually. CZ-V21/V22 Digital display amplifier MODE button Current value display SET button One-touch calibration The touch of a button completes the sensitivity setting. Quick plug-in connector (Receiver side) Set value display Manual buttons 1-line connection supported. Interference prevention for up to 2 amplifiers 4 outputs x 2 channels Heatsink Fiber cable (Transmitter side) CZ-V21 (Main unit) CZ-V22 (Expansion unit) Power is supplied through the connector on the side, saving connection cables. 5

6 A wide variety of detection applications from every industry Unacceptable Acceptable Detecting the presence/absence of grease By canceling the influence of surface luster and target position, the CZ-V20 reliably detects grease, despite its non-uniform shape and position. Detecting a mark on a tube Selecting the small beam spot allows stable detection of small marks even from a long distance. Checking parts assembly The enhanced detection ability ensures stable detection of darkcolored targets. Detecting the presence/absence of O-rings The optimum beam spot can be selected according to the target. Detection by color recognition is stable even for targets with variable shapes. Detecting improperly positioned labels Detection is stable because the color recognition is not affected by the change in bottle colors. The interference prevention function assures successful detection when two sensor heads are mounted in close proximity. Detecting the seam on a spray can Even when patterns are printed on spray cans, the sensor detects only the seam. Detecting caps of different colors The CZ-V20 Series stably detects subtle color differences that are difficult to detect with conventional sensors. Since detection is based on RGB components, it is less affected by target position or vibration. Detecting defective marks on PC boards Detection is stable even for dark-colored targets. The dual digital display allows easy sensitivity adjustment in fine increments. 6

7 Detections that were once difficult can easily and reliably be achieved. ( Mode) World s First Automatic selection of 7 different light combinations (Patent pending) In the mode, the sensor detects the received light and automatically selects the most stable light from seven patterns. (There is no need for complicated settings because the light source is automatically selected during the sensitivity setting.)* * In reality, the color of the emitted light does not change because the light combination is selected by the receiver. Red Green Blue Red + Blue Blue + Green Green + Red Red + Blue + Green SUPER mode + 3 LEDs for exceptionally powerful detection SUPER 16X TURBO FINE 2X 8X 3 LEDs Red, green, blue HSP (High speed) 1X level The combination of the SUPER mode + 3 high-intensity LEDs has achieved unrivaled detection power. Even dark-colored targets can be reliably inspected. Three detection modes for every target Detects the received light C Detects the color components C+I Detects the color components and received light 7

8 Advanced features that provide 100% reliability Four independent outputs This function is useful for target differentiation. The sensor stores data of four types of targets simultaneously and allows the setting and output for each target independently. When the C or C+I mode is used, the bank function enables differentiation of up to eight different types of targets. C C+I Shift function This function is useful for detecting subtle color differencs. When there is a change in the surrounding environment over time, the displayed value can be compensated with the external shift input. (Patent pending) Shift input When the difference in sensitivity between the target and the background is small, providing shift inputs periodically will compensate for data variations. External calibration function C C+I The sensitivity can be adjusted by using an external device such as a PLC. Automatic calibration adjustmant C C+I After the sensitivity setting is complete, the set value can be finely adjusted by detecting actual acceptable or unacceptable targets and adding (increasing) or excluding (decreasing) the set value. (Patent pending) Attenuation function C C+I When the reflection from a target is too strong, the attenuation function can be used to decrease the sensitivity. Three types of timer functions C+I Built-in self-stabilizer C C+I The self-stabilizer internally monitors fluctuations of the transmitted light due to temperature changes or aging, and automatically adjusts the light intensity to a constant level. C Three types of timers are available: ON-delay, OFF-delay, and Oneshot. The timer value can be set between 1 ms and 1,000 ms.
