TOF/Spot-Safety
5.

Overview

Based on Time-of-Flight
TOF/Spot-S consists of an active infrared emitter and
receiver combined in the same housing. There is one size
of spot-like detection area available which reflects an exact
picture of the safeguarded area.
One output signals the detection of an object within the
detection area.

Detection area dimensions

The maximum detection range is 6 m (20 ft). Object
detection at a range less than 0.2 m (0.7 ft) cannot be
guaranteed.
The TOF/Spot-S features a detection area of 20 mm ×
20 mm at 2 m (0.79 in × 0.79 in at 6.5 ft) range. It reads the
correct distance and switches the output reliably for objects
covering the full beam size (detection area). For objects
being only partially in the detection area, a correct distance
evaluation cannot be guaranteed.

Figure 11: Illumination size of the TOF/Spot-S
As the illumination size is bigger than the detection size,
at 2 m (6.5 ft) range, the TOF/Spot-S needs at least
20 cm (7.87 in) space to the next sensor to avoid
interference.
