SC300 Hand Detection Safety Sensor

ab guardmaster sc300 handdetect smlThe Allen-Bradley® Guardmaster® SC300 is a Type 3 vision-based protective device designed for use in a variety of machine guarding applications.

This latest addition to the Rockwell Automation® safety opto-electronic product family is targeted to light and medium industrial machine guarding applications which have a square or rectangular frame in front of the hazardous area and an environmental rating requirement of IP54.

The sensing function is performed by the SC300 viewing a two-dimensional image against a passive pattern as the background. The detection principle is that the view of the pattern is blocked by an object of the appropriate resolution (24mm or 30mm).
