A vision sensor built for stability and simplicity. With built-in camera and optimized lighting, a wide area can be captured with an image and stable detection of multiple targets is possible even if they are misaligned. KEYENCE CMOS image sensors convert light into digital image data, to be sent to the controller in as little as 2 ms. Lenses are used to focus the light onto the camera’s image sensor. KEYENCE’s high-resolution, low-distortion lens options ensure stable inspection across the whole image.
Vision sensor is utilized for detecting defective object, measurement size of object, character recognition,sorting objects, etc. Vision sensor utilize image processing technologies like distinguishing “White or Black”, “Bright or Dark”,”Deep color or Thin color”, “Difference of the color”, etc. Vision sensors share several common components with vision systems, including lighting, lenses, image sensors, controllers, vision tools, and communications protocols There are two types of vision sensors, the monochrome model, and the color model.
The difference between vision sensors and vision systems is fairly basic: A vision sensor does simple inspections like answering a simple yes-no question on a production line. A vision system does something complex like helping a robot arm weld parts together in an automated factory. Each cell of a CCD image sensor is an analog device. When light strikes the chip it is held as a small electrical charge in each photo sensor.
