3.2.2.3.2 Sensor assembly with the standard assembly bracket
REA JET offers three, virtually identical in terms of mechanical dimensions, product sensors. They
can be mounted directly to the print head and differ only in terms of functionality. The assembly
steps for these three sensors are the same and are described in the following using the example of
the energetic reflection light sensor.
Figure 52: Delivery scope of the photo-optical product sensor
The sensor is equipped with two M3 through-hole threads at the upper and lower end in the front
area for assembly. The delivery includes by default two "
long
" (M3 x 16mm) screws (A) for
fastening to the assembly bracket. The long screws are used to fasten the sensor to the assembly
bracket.
Figure 53: Scope of delivery of the assembly bracket for the photo-optical product sensor.
The assembly bracket is used to mount the photo-optical sensor directly to the print head. It can be
mounted to both sides of the print head. The scope of delivery includes two "
short
" (M3 x 8mm)
screws (B) and a cable tie. The short screws are used to fasten the sensor to the print head.
As it is important to use the correct length screw for its intended purpose, both types of screw are
illustrated in the following figure to enable the reader to see the difference.
