LI5040SAI
Canon
With an electronic shutter and all pixel progressive readout of 120 fps, the 5MP CMOS sensor offers fast, enables the capture of distortion-free images even when shooting fast-moving objects. In a 2/3″ format, proprietary pixel designs with low power consumption and enhanced sensitivity further improve performance.
- Enhanced Near-Infrared Sensitivity 5MP GS CMOS sensor (RGB-NIR)
- Overlap Trigger Mode (External Trigger Width Control Mode)
- Full area readout: 120 fps
Features
Adopts a global shutter that exposes all pixels simultaneously. This allows for the accurate image capture of even subjects moving at high speeds, making the sensors ideal for cameras performing such tasks as inspecting parts on factory conveyor belts.
Using a high frame rate would lead to increased electricity consumption. However, through proprietary Canon circuit technology, the sensors achieve low energy consumption.
In the external trigger width control mode, it’s possible to control the exposure time with the width of the Low period of the external trigger (TRG). Readout and exposure can be overlapped.
About this series
Specialized RGB-NIR Pixel Filter Array
By replacing one of the green filters on a standard colour CMOS sensor with a Near Infra-Red (NIR) filter, image processing from this sensor allows for the separation of visible and NIR spectrums.
Near-infrared images can be used to check for internal foreign matter, and colour images for printing errors on the surface of packages.
Overlap Trigger Mode for Factory Automation application
In the external trigger width control mode, it’s possible to control the exposure time with the width of the low period of the external trigger (TRG). Readout and exposure can be overlapped. This delivers a high frame rate.
