Wiring diagram
Convergent mode sensors are equipped
with a lens before the emitter diode that
produces a small and intense focal point at
a defined distance from the sensor. Similar
to diffuse mode sensors, the light reflected
by the target is evaluated. Convergent
mode sensors are ideal for detection of
small targets or colour marks and edge gui-
ding or positioning control of transparent
materials. The targets must always be wi-
thin the focal depth of the sensors. The fo-
cal depth is defined as the area before or
behind the focal point within which the ob-
ject can be detected. Based on the intense
light concentration in the focal point, con-
vergent mode sensors are capable of de-
tecting targets with a low reflectivity.
