Contact Image Sensors (CIS)
High-quality, high-performance CIS developed based on many experiences through more than 30 years!
Mitsubishi Electric develops unique key parts-everything from CMOS sensor integrated circuits (ICs) to illumination based on know-how and expertise accumulated through many years of solid results. This enables our products to provide high-speed digital output of clear, vivid high-definition images. Our high-quality, high-performance CIS are utilized by many customers in a variety of ways, including application in copy machines, ATM cash sorters, and surface inspection machines both in Japan and around the world.

Applications
All forms of surface inspection are supported, from printed material/label/package inspections to length measurement inspections. You can utilize the CIS to find scratches, dirt, part defects, and color defects by connecting it to your software.

| Compared to an optical reduction line camera system, CIS offer smaller distortion in the peripheral area of scanned image and are therefore suitable for length measurement. | Color reproduction is the same level as that achieved using standard line cameras. |
Features
1. Ease of installation - Compact device (module)
The KD Series CIS includes the image sensor, lens and LED illumination in one package. The fixed focal distance saves installation time with the use of simple brackets and mounting.
2. One CIS captures a long, wide picture all at once
Three scanning widths are selectable, from 309㎜ to 926㎜, as a module for the application.
To suit each scanning width, the lens, light source and sensor (photodetector) have been integrated into one product, thereby eliminating the hassle of equipment adjustment when using multiple line cameras.
3. Distortion-free & uniform images
The GRIN lens system, which transfers a real, erect image at the same magnification and has same length as each scanning width, is used for Mitsubishi Electric CIS.
Thereby image distortion in the peripheral region of the scanning image is minimized and inspection accuracy is more stable compared to conventional line cameras and optical reduction scanning methods.
4. Clear edge detection
The CIS system captures clearer images than conventional line camera systems. This makes it easy to determine minor defects.
5. Lineup includes both built-in light source and no light source
CIS with built-in illumination are equipped with our standard white LED array. There are also non-LED options for backlight or other custom lighting strategies. It is flexible to set CIS and the illumination at any viewing angle.
6. Monochrome output model
The new monochrome CIS has been proven complaint and carries the CE marking. It has a camera link connectors concentrated in one spot, and a transfer speed twice as fast as color models!
Easier cable routing is realized by placing the CameraLink® connectors in one place regardless of scanning width. The number of cables can be reduced for low-speed scanning, which helps to reduce peripheral costs.
