The COUP2000EX Pro adopts a transmitter-receiver fiber optic sensor, which determines the
difference in the amount of incoming light sensed by the sensor under two conditions: with
and without parts in the material strip.
Therefore:
*For black plastic material strips with no holes in the center of the part slot (as shown in
Figure P1, this function is invalid!
*For a completely transparent material strip, the amount of light entering when there are no
parts in the part slot is very close to the amount of light entering the material strip between
the part slots (as shown in the Z part of Figure 3-1), which can easily lead to misjudgment.
*This function can be achieved for black plastic material with holes in the
Center of the part groove and paper material strip
4.2.2 Pocket Check device consists of three parts ：
4.2.2.1 Fiber
We have updated to use SUNX's transmitter-receiver type fiber FX-501-C2, which can also
be replaced with other transmitter-receiver type fibers of the same grade, diameter, and
flexibility。

4.2.2.2 Fiber optic alignment mechanism
To activate the empty material detection function for different widths of material strips, the
fiber optic alignment mechanism must be relaxed first to align the fiber optic emitting end
with the center hole of the part slot on the material strip (i.e. D1 in Figure 3-1), and then
locked.

4.2.2.3 Amplifier for FX-501-C2
4.2.2.3.1 Part description：
4.2.2.3.2 Threshold value of the amplifier
The threshold value is very important, this value represent the difference of 2 status, with
and without components. When using pocket check function, we need to set this
threshold value. Once the light input exceeds the threshold value, the amplifier will
determine that there are missing parts in the material strip. As shown in the figure below:
