描述

I. overview
GDJ series photoelectric sensor (valley called photoelectric head, photoelectric eye) using light emitting and receiving principle, a modulated light, reflective of the measured object, and to distinguish between different colors according to the received optical signal intensity, or recognize the existence of objects. Used as a sensor with a circuit or device in the flexible packaging machinery, printing machinery, food machinery, textile and paper machinery, automatic control system, for color printing in one color on the background, or other as a marker of pattern color, lines, or objects have no detection, can realize automatic positioning, set long, color correction, and other functions, to version.Integrated optics technology, the sensor of semiconductor optoelectronic technology, modulation and demodulation technology, using SMT advanced surface mount technology, has the advantages of high sensitivity, quick response speed, strong anti-interference ability, compact structure, easy to use.GDJ-411 is the company according to the development of new varieties of user requirements, it is particularly suitable for miniaturization photoelectric sensor particles, liquid, powder, paste vertical packaging machine, pillow packing machine, bag making machine.

II. characteristics

1, there is resistance to external light interference and electromagnetic interference is very strong;

2, precision metal die casting shell (150 tons casting machine), good heat dissipation, electromagnetic shielding and sealing;

3, the sensitivity (sensitivity) to adjust how ring, single ring potentiometer two specifications, can be selected by the user;

4, using the optical coating technology advanced, color discrimination ability. And can be well used for detection of gold foil, aluminum foil and transparent film.

5, the power reverse polarity protection and output short circuit protection;

6, using advanced SMT technology.

III. work principle

The objects with different colors to the same color of the incident light with different reflectivity; the same light emitted intensity unchanged, according to the reflected light signal received strength, can distinguish between different colors, or identify objects have no. The sensor working principle as shown in figure 1. Source L sends modulation pulse light, photoelectric receiving no reflection optical signal G receiving objects, and converted into electric signals, and then through the detection, amplification, filtering, comparison and amplification, drive the output level (switch) signal.
