Vision & Control GmbH has launched the S26 and S28, compact machine vision sensors that include a tutorial and that offer automatic parameter preselection. Providing full VGA resolution, they are suitable for identification and comparison of patterns in optical inspection applications that require recognition of minute differences in the test object. The S26 is supplied with optics, lighting, electronics and software, and the S28 offers a choice of optics and lighting. Both use gray-scale processing and have a user interface that supports fast start-up and easy changing of parts. Processing steps and defect images can be stored in the sensors. The acquired data can be transferred for use with smart cameras and multicamera systems.
