Operating principle of the device
Figure 1 - Operating principle of the SC300
The SC300 safety camera system comprises a camera as well as a reflective tape with
which the contour to be monitored is defined.
The camera monitors the area bounded by its field of view and the reflective tape – the
protective field – for interruptions. If the SC300 detects an interruption in the shape of
the protective field, the camera shuts down its safe outputs.
Please refer to “Technical Specifications” on page 47 for the data sheet. Please refer to
page 50 for the dimensional drawings.
