In many industrial processes, it is not only important that an object is present, but also that it is in a specific position or on the conveyor belt at a specific distance from the machine. Even checking whether an object is separate or lying on top of another object on the conveyor belt can be crucial for the subsequent (packaging) process steps. To perform these tasks with a single sensor, the sensor must supply both switching and measuring information to the machine control. We have achieved this with the development of the new ODT 3C.
