Introduction
GDJ series photoelectric detecting sensor (Its popular name is photoelectric head
photoelectric eye) adopts the principle of photoemission and photo receiving. It shots
out modulated ray to the measured object and receives the ray reflected from the
measured object, then according to the intensity of the received ray to determine the
color of the object or to distinguish whether or not is the object existed. As a sensor it
is used in the control systems of the soft packaging machine, the printing machine,
foodstuff machine, textile and papermaking machine together with other circuits and
devices. It can also detect the color-mark printed on the color-background or other
pattern color block as its mark and can check whether or not are the lines and objects
existed. It have the functions of automatic orientation, deciding constant length,
distinguishing color, correcting error, checking edition, counting number, etc.

3. Principles
The objects having different colors are provided with different reflectivity for the
same incident light. Hence, when we emit the light with constant color and constant
intensity, we can distinguish different color or determine whether or not the object is
existed according to the intensity of reflected light that was received by the sensor.
