Device for use in sensor system for securing object e.g. mechanical switch, against changes in e.g. stamping tool, has evaluation device formed as evaluation logic device and comparing two-dimensional images in image signal with each other

摘要

The device (10) has an image sensor (12) for receiving radiation (31) from an observation surface (18) and for outputting a signal (S1). An evaluation device (15) receives the signal and determines a change in the signal to detect a change in position and to output an alarm signal (S2). The image sensor is utilized to perform angle-resolved detection of the surface and to output image signals. An imaging lens (14) maps the surface on the sensor. The evaluation device is formed as an evaluation logic device and compares two-dimensional images in the image signal with each other. An independent claim is also included for a sensor system with a device for securing an object against changes.
