Vision Sensors analyze images to perform appearance inspections, character inspections, positioning, and defect inspections, Most of the time a quite user-friendly software interface is supplied which essentially simplifies the use for many standard applications.By melting together image capture, digitalisation and evaluation into a small module, designing the system has become much easier for the integrator and use.Due to the compact design, many vision sensors and smart cameras have high IP protection classes and can also be used in rough environments.
