Wiring diagram
Just like with retro-reflective sensors, op-
posed mode sensors incorporate the emit-
ter and receiver circuitry in a single housing.
However, diffuse mode sensors do not de-
tect the interruption of the light beam but
the reflection of the target. A target is de-
tected if it reflects a sufficient amount of li-
ght back to the receiver. The switching
distance of diffuse mode sensors thus lar-
gely depends on the reflectivity of the tar-
get. This type of sensor is especially suited
for detection of transparent objects (diffuse
mode sensor with or without background
suppression or convergent mode sensors).
