Color Mark Sensors

GDJ-511, GDJ-411, GDJ-211, GDJ-311
* NPN, PNP output or analot output
* Light source: green, green + blue, red or white

* According to the principle of photo emission and receiving, color mark sensor sends out modulated ray to the target object, and receives the ray reflected from the object. The color of object can be detected or the object can be identified existed or not by the intensity of the reflected ray.

* High capability to reject the radial and the electromagnetic interferes.
* Housing: Precision die casting metal housing, well heat elimination, electromagnetic shield and compatness.
* With light -on and dark-on function, with output LED indicator.
* Sensitivity adjustable by point meter, single loop or multi loops optinal to user.

* Against polarity reversal, short circuit and overload protection.
* Adopt SMT automatic techinique.
* Capable of detecting transparent objects.

* Application: Color mark sensor is used in the control systems of the soft packaging hine, the printing machine, food stuff machine, textile and paper-making machine as well as other cuircuits and devices. It can also identify the color mark printed on background color.
