4. Sensor Mounting and Installation
When mounting the SR50, the sensor's beam angle needs to be considered (see
Figure 5). It is important to remember that the SR50 has a beam angle of
approximately 22 degrees. This means that no objects should obstruct the
intended target within this 22 degree beam. If an obstruction is within this
beam angle the SR50 may detect the unwanted object instead of the intended
target. By inserting a height value in Formula 2, a Clearance Radius in the
same measurement units as the height can be obtained.
