The object mode enables the SUPERPROX ® sensor to operate as a universal, all-materials-type, proximity detector.

Sensing in this mode is done by first setting the window limits as shown in Figure 1 and ensuring that the object surface is properly positioned in-line and parallel (See Figure 2) with the sensor face.

In this mode, the sensor accepts all ultrasonic pulse echoes received from objects that are either at or within the window limits as shown in Figures 2 and 3a. All echoes, excluding coincidental secondary echoes (explained below), received from objects outside the window limits (See Figure 3b) are ignored.
