5.5 Side Approach

For the side approach, Figure 5-7 and Figure 5-8 show the resulting detection field using the approach shown in Figure 5-6. The detection field is very symmetrical along the X-axis with a maximum detection distance of approximately 0.75 inches at 0.25 inches in either direction off the axis, with the detection tapering from this point outwards.

Figure 5-9 shows the DRV5032 side approach field to better show the axes values and the field shape. The Z axis height sharply tapers at 0.6 inches above the device and is no longer perceptible after approximately 0.8 inches.
