Illumination size of the TOF/Spot
As the illumination size is bigger than the detection size,
at 2 m (6.5 ft) range, the TOF/Spot needs at least 20 cm
(7.87 in) space to the next sensor to avoid interference.
5.2 Alignment
As the detection area of the TOF/Spot looks like a square,
it is important to know where the flat borders and where
the edges are:
Important:
For proper functionality, the remission range of the
background or the object has to be between 2 ... 90%.
Do not use high reflective, retro-reflective or mirroring
backgrounds or objects. They can lead to malfunction
of the sensor due to the emitted beam not being
directly remitted back to the sensor, which leads to
measurements out of the operating range.
6. Configuration and operation
There are different TOF/Spot types available. Some of them
need to be set manually, others are factory set.
IMPORTANT
The sensor uses a ±40 mm (±1.57 in)
hysteresis. The hysteresis is the difference
between the switching points changing the
status from “free field” to “object detected”
and back from “object detected” to “free
field” compared to the nominal limit.
