5.6 Alignment
When using the WLL80 fiber-optic sensor with through-beam fibers, align the sender fibers with the receiving
fibers. Select the position so that the emitted light beam hits the receiver. Tip: Use white paper or a reflector as an
alignment aid. The sender must have a clear view of the receiver. There must be no object in the path of the beam
[see figure 8]. You must ensure that the optical openings (fiber surfaces) of the fibers are completely clear.
Figure 8: Alignment of through-beam fibers
When using the WLL80 fiber-optic sensor with a proximity fiber, align the fiber to the object. Select the position
so that the emitted light beam hits the center of the object. You must ensure that the optical openings (fiber
surfaces) of the fibers are completely clear [see figure 9].
