5.1 Basic concepts
5.1.1 Determining factors
The optimum position of the sensor depends on:
l sensor field of vision
l depth of the dangerous area (and therefore the stopping area)
l sensor installation height
l sensor inclination around the transverse axis
l the presence of other sensors (see "Applications" on page35)
The actual field of vision of the sensor depends on the height of installation and inclination of the sensor.
5.1.2 Sensor installation height
The installation height (h) is the distance between the center of the sensor and the ground or installation
base of the sensor.
5.1.3 Sensor inclination
Sensor inclination is the rotation of the sensor around its transverse axis. Inclination is defined as the angle
between the center of the sensor's field of vision and a line parallel to the ground. Three examples are
presented as follows:
l sensor tilted upwards: α positive
l straight sensor: α = 0
l sensor tilted downwards: α negative
