TOFniva

4. Introduction

The TOFniva is a compact yet powerful and flexible range
of sensors. These detect people and objects within a planar
area of max 2.0 m by 2.0 m. TOF technology enables
TOFniva sensors to operate with all types of backgrounds
without any need to recalibrate. Their main feature is their
ability to easily adapt to different detection field needs –
this is done using two potentiometers for x-axis and y-axis.
TOFniva sensors are available with and without blanking
in both center and side mounted versions.

5. Configuration

Type of threshold setting

The distance at which the sensor triggers an output is the
threshold. The TOFniva requires a threshold setting for the
x-axis as well as the y-axis using potentiometers. A factory
setting as well as a mixture of potentiometer and preset
are also possible on request.
Note: The sensor uses a ±120 mm (±4.72 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.
5.1.1 Threshold setting via potentiometer
The threshold distance at which the sensor triggers
an output is set with a potentiometer for the x-axis and
y-axis. This is done using the potentiometer at the back
of the sensor. If the sensor points to a background, the
distance of the switching threshold to the background is
recommended to be set at 150 mm.
Important:
The cable exit of the sensor in the Figure 3
is always at the bottom.
