1. Introduction
GDJseriesphotoelectricdetecting sensor(Itspopularnameisphotoelectrichead
photoelectriceye)adoptsthe principleofphotoemission and photoreceiving. Itshots
outmodulated raytothe measured objectandreceivesthe rayreflected fromthe
measured object,then according tothe intensityofthe received raytodetermine the
coloroftheobjectortodistinguishwhetherornotisthe objectexisted.Asasensorit
isused inthecontrolsystemsofthe soft packaging machine, theprinting machine,
foodstuffmachine, textileand papermaking machine togetherwithothercircuitsand
devices.Itcan alsodetectthe color-markprinted on thecolor-backgroundorother
patterncolorblock asitsmarkand can check whetherornotarethe linesand objects
existed. Ithavethe functionsofautomaticorientation, deciding constantlength,
distinguishing color, correcting error, checking edition, counting number, etc.

3. Principles
The objectshaving differentcolors areprovided withdifferentreflectivityforthe
sameincidentlight.Hence, when weemit the lightwithconstantcolorandconstant
intensity,wecan distinguishdifferentcolorordetermine whetherornotthe objectis
existed according to the intensityofreflected lightthatwasreceived bythe sensor.

5．Installationand Wiring
1. The sensorshouldbe setupverticallyon the top ofthe measured object.The
distance betweenthe surfaceofmeasured objectshouldbe approximately10mm
tothe sensorlensaccordingtothedifferentmodel.Theverticaladjustment
distance ofmounting base plate should be 10mm.
2. The sensorhasfourwireswhich differentiated byitscolor.Wiring showninthe

6．Sensitivity adjustment
In general, （No matterthe lightaimsto the deep colororlightcolorobject）Rotating
the knob ofsensitivitybyclockwise, then the green light(OUT1)turnson.
Firstly:Make the light-spotaimstothe darkcolorside ofobject(Generallyascolor
patch),adjusttheSensitivityknob,and make thegreenlight-spotjustbe inthestatus
ofdisappeared,rememberthe position ofthe knob (NotesA).
Secondly:Make thelight-spotaimstothe lightcolorside ofobject(Generallyas
background color),adjusttheSensitivityknob byanticlockwise, andmake the green
light-spotjustbe inthe statusofdisappeared, rememberthe position oftheknob
(NotesB).
Thirdly:Turnsknob to the middle ofAand B.
Notes:Becausethe Sensitivityknob ismultiturnpotentiometer.Notonlyremember
the position ofAand B, butalsorememberthe numberofknobturns.Then, turnback
the knob to themiddle ofnumberofknob turns.
