photoelectric mark sensor

Description

General Description 

GDJ series photoelectric detecting sensor (Its common name is photoelectric head photoclectric eye) adopts the principle of photoenmission 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 the object exists. As a sensor it is used in the control systerms 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 has the functions of automatic orientation, deciding constant length, ditinguishing color, correcting error, checking edition, counting.

 

Features

  • High capability to reject the radial and the electromagnetic interference.

  • Precisions die casting metal case, well heat elimination, electromagnetic shield and compactness. Red and green status indicators, adjusting the sensitivity with either multiple or single loop potentiometer that was selected by user.

  • Adopting the advanced optics pasting technique, the limpidity ability is very strong. Can used to detect the gold foil, aluminum foil and other transparence thin foil well.

  • Having the safeguard in the power supply applied in reverse and the short circuit of the power lines.

  • Adopting the advanced SMT technique.
