Analog output A sensor with an analogoutput does not switch at aparticular target distance.These devices havean analog output with adistance-dependent
output signal. The outputvoltage is proportionalto the object point in thesensing area.These systems operate onthe same principle as
sensors with backgroundsuppression. They generatea linear output signal withina certain range (measuringrange)
Focusing To achieve a smaller lightspot, the light beam fromthe emitter is focused usinglenses. Focusing and theresulting light spot allow the
switch to better detect smallparts and details.Focusing is often used withretroreflective sensors, aswell as with diffuse sensors,

and in conjunction withbackground suppression.
Gray scale shift Gray scale shift is theswitching distance differencewhen calibrating usingdifferent object reflectivities.The sensor is calibrated fora distance using a Kodak
gray card with 90 %reflection. A Kodak graycard having 18 % reflectionis used and the resultingdistance measured. Thedifference between these
two switchpoints in % isreferred to as the gray scaleshift. The smaller the grayscale shift the less color-dependent the sensor willbe.

Background suppression(background suppression)
Background suppressionallows objects within acertain switching distanceto be detected withoutbeing affected by a reflectingbackground and virtuallyindependent of objectreflectivity (color or surfacetexture).Background suppression isrealized by allowing the beamcones of the emitter and
receiver to intersect. Thisresults in a division of the fieldof view intoan active area and thebackground. In addition, bydividing the receiver intoat least two adjacent areas(e. g. by using a dual diodeor a PSD element) andby means of a geometricarrangement (triangulation),the actual position of the
object within the sensingrange can be determined.These two design featuresallow the object to be reliablydistinguished from thebackground. Diffuse sensorswith background suppressionare characterized by low grayscale shift and hysteresis.

Kodak gray card The “standard target” forphotoelectric sensors is theKodak gray card. This isa cardboard sheet whose
surface has a defined degreeof reflectivity. The sidewith 90 % reflection is usedfor determining the range of
diffuse sensors, and the sidewith 18 % for determiningthe gray scale shift.
Short circuit protection The output leads can beconnected to the wrongpotential without destroying
the sensor. Together withtheir polarity reversalprotection, these sensors
are completely protectedagainst miswiring.
Laser, laser class The purpose of laser classesis to protect persons fromlaser radiation by specifyinglimit values. Based on this,the lasers used are classifiedaccording to a scalereflecting the degree ofhazard. The calculations andassociated limit values for theclassification are described inEN 60825-1:2001-11. Thegrouping is based on acombination of output powerand wavelength, taking intoaccount emission duration,number of pulses and angleextension.
Balluff sensors operate inthe following laser classes:
Class 1: harmless,no protective measuresnecessaryClass 2: low power, eyelidreflex is sufficient protection.
Appropriate warning labelsmust be affixed to thedevice and in some casesto the machine in whichthe laser is used. No othermechanical or opticalprotection measures arerequired. When usingdevices from Class 1 and 2,no person responsible forlaser protection needs to bepresent.

Diffuse With diffuse types, theemitter and receiver areintegrated into a singlehousing. Orientation to thetarget is not critical.A target object (e. g. astandard target which is90 % reflective) bounces apart of the light from itssurface back to the receiver.Once the standard targetenters the effective beam
(see illustration), a changein the output switching stateoccurs.The sensing distancedepends upon size, shape,color and surface charac-teristics of the reflectingtarget object.Using a Kodak gray cardwith 90 % reflectivity (like

Teach-in Sensor settings on teach-insensors do not have to bemade using a potentiometeror slide switches; everythingis controlled with the push ofa button. The microcontrollerintegrated into teach-insensors allows the entiresetup sequence to becontrolled by pressing the
button. The use of definedcalibration steps also meansthat the sensor cannot becalibrated for an unreliablezone. The microcontrolleralso assumes control of thecontamination indicator andthe contamination output.A variety of Balluff teach-insensors also provide the
option of remote operation,whereby the teach-incalibration process isinitiated “externally” througha cable line.

BODDistance Sensors
Optical distance sensorsare used when distancesof objects need to bemeasured or monitored ortheir precise positiondetermined.
Distance measurement isbased on the principles oftriangulation or speed of lightmeasurement.
PSD elements or CCD arraysare used for the receivingelements, with the emitterconsisting of a red light orlaser light source.
Analog current and voltagevalues, serial interfaces anddigital outputs are availableto the user.

The BOD 63M in itstough metal housing has aworking range of200...2000/6000 mm. Itfeatures adjustablebackground fade-out and ananalog output of 0...10 V or4...20 mA.
Speed of light measurementenables longer rangesthan triangulation-based orenergetic diffuse sensors.
The switching outputsare set using a multi-turnpotentiometer.
This innovative sensortechnology is used inapplications where traditionalmethods meet eithertechnological or economicallimits. Such applicationsinclude detecting smallobjects at great distancesand operating in difficultconditions. e.g. if sensingmust be performed“externally” in process withhigh temperatures or inrobotic cells.
Applications
– Exact detection tasks overlong distances (e.g. due todesign limitations or heatat the target location)
– Detecting objects withchanging colors, shinysurfaces or unfavorableangle to the light beam
– Flexible solutions forposition sensing, leveldetection and monitoring,distance and heightmeasurement, qualityassurance applications

Laser class(see page 55)
The emitter meets LaserClass 2 perEN 60825-1:2001-11.This means no additionalsafety measures arenecessary.
Install the device so that thelaser warning label is easilyvisible.
Features
– Small laser spot fordetecting small objectsover large distances
– Virtually independent ofthe reflective properties ofthe target object withina particular sensing range
– Background suppression(HGA) over the entireworking range
– Analog, binary and alarmoutput
– Laser beam can be turnedoff
These sensors are also available asIO-Link types.Please request our separate IO-Linkbrochure!
