Switching frequency 100 Hz / 500 Hz<br />
2x PNP or NPN, 4-20mA, RS485<br />
Specification:<br />
The LDS 400 series offers an innovative<br />
laser distance sensor with time of<br />
flight measurement. This technology<br />
is based on the measurement of the<br />
time between the emmision and the<br />
receipt of the laser light pulses.<br />
In the 300-4000 mm distance range,<br />
it provi<strong>de</strong>s a very accurate measurement<br />
in<strong>de</strong>pen<strong>de</strong>nt of the target's<br />
colour with 12 bit resolution and high<br />
linearity. A 4-digit display on the<br />
sensors top visualises the value of<br />
the measured distance in mm, as well<br />
as all the parameters that can be set<br />
with three pushbuttons.<br />
The LDS 400 sensors have two<br />
switching outputs, available as PNP<br />
or NPN mo<strong>de</strong>ls, that can be set at<br />
different distances, while the<br />
measurement value ist supplied at<br />
the 4-20 mA analogue output and<br />
RS485 interface. This interface can<br />
also be used to set all the parameters.<br />
A response time selection with 5 ms<br />
normal and 1 ms fast response is<br />
available.<br />

RS485 serial connection<br />
The RS485 serial interface allows the complete remote control of the<br />
sensor. All functions as channel status, normal/fast mo<strong>de</strong> selection or<br />
output <strong>de</strong>lay can be configured by serial connection. The serial<br />
communication parameters are:<br />
9600 baud, non-parity, 8 data bits,1 stop bit.<br />
The SYNC-input is used to <strong>de</strong>termine the communication direction.<br />
SYNC active (LOW)<br />
LDS400 -> user<br />
SYNC passive (HIGH)<br />
user -> LDS400<br />
With SYNC active, the sensor continuously transmits the <strong>de</strong>tected<br />
distance value (with a precision of 12 bit) by means of a binary data<br />
format. 2 byte are used; one with bit 0 at logic level 1 i<strong>de</strong>ntifies the high<br />
byte.<br />

Keylock (SET pushbutton block)<br />
The keylock function is activated after powering on, if the SYNC terminal is connected to the positive<br />
power supply (+VDC) for at least 1 s.<br />

To <strong>de</strong>activate the keylock function, the sensor has to be turned off and re-powered while maintaining<br />
the SYNC wire not connected or ground connected (GND).<br />
SYNC-Input<br />
The SYNC signal allows to calculate the beginning and the ending instants<br />
of the measurement. Reading cycle beginns after the transition of the SYNC<br />
signal from passive to active and the sensor outputs are updated after<br />
max. 400 µs. All the outputs are <strong>de</strong>activated after max. 400 µs from<br />
the active-passive transition. (SYNC passive=Vcc, SYNC active=GND)<br />
The SYNC wire is also used to <strong>de</strong>termine the transmission direction<br />

system with extensive functional features. Through the<br />
integral controller the system can be completelyconfigured<br />
via the supplied PC software and also offers extensive<br />
functions such as limit switches, averaging, adjustable<br />
measurement ratesand the synchronizationoftwosensors,<br />
e.g. for thickness measurement. With the unique Real-Time<br />
Surface Compensation (RTSC) the system facilitates<br />
measurements against awi<strong>de</strong> range of material surfaces<br />
(e.g. bare metals, black rubber or shiny painted surfaces).<br />
Due to the large selection of different measurement ranges<br />
from 2 to 750 mm there is a perfect sensor for each<br />
application. The compact <strong>de</strong>sign makes the series LDS 85<br />
sensors particularly suitable for industrial applications in<br />
automatedmachineryandproductionequipment.<br />
The series LDS 85 operates according to the triangulation<br />
principle.Alaserdio<strong>de</strong>projectsavisiblespotoflightontothe<br />
target surface. The light reflected from this spot is directed<br />
throughanopticalreceivingsystemontoaposition-sensitive<br />
element(CCDarray).Ifthetargetchangesitsdistancetothe<br />
sensor,this leads to achange of the imaging spot on the<br />
CCDarray.Thepositionofthespotinci<strong>de</strong>ntontheCCDarray<br />

ADVANTAGES<br />
• RTSC fast adaptation to changing surfaces<br />
• Compact <strong>de</strong>sign with integral electronics<br />
•Configuration and control via software PC<br />
• Synchronization of two sensors mandatory<br />
for differential and thickness measurement<br />
• Analog and digital outputs<br />
•Programable limits<br />
Performanceproof<br />
Every sensor is calibrated according to ISO<br />
9000 quality standards and an individual<br />
calibration protocol is inclu<strong>de</strong>d with every<br />
sensor.<br />
Compact<strong>de</strong>signwithintegralcontroller<br />
Despite its compact dimensions, the LDS 85 series has a<br />
completely integrated controller. There is no separate<br />
controllerhousingwhichmeansthatinstallationandwiringis<br />
carriedouteasilyandquickly.Itssmallsizeallowsthesensor<br />
tobeintegratedintotightinstallationspaces.<br />
The measurements are processed digitally in the integral<br />

required).<br />

Typical applications<br />
Contourmeasurementoncatalyticconverters<br />
During the production of ceramic billets for car catalytic<br />
converters, the billets are measured for roundness and<br />
diameteronanumberofradialtracksforclassification.Using<br />
the IF2004 interface card (page 6),<br />
the enco<strong>de</strong>r and sensor signalsare<br />
synchronized to obtain precise<br />
correspon<strong>de</strong>nce in angle and<br />
shape.<br />
Partsmeasurement<br />
On machined surfaces of metal products,<br />
the LDS 85 is employed for quality<br />
assurance.Quantitiessuchasroundness,<br />
concentricity, eccentricity and bending<br />
<strong>de</strong>flectionare<strong>de</strong>termined.<br />
Synchronousthicknessmeasurement<br />
Thethicknessofthevariouswebmaterials<br />
can be reliably acquired with LDS 85<br />
sensors. With their high measuring rate<br />
andthepossibilityofsynchronizingtwoor<br />
more sensors (simultaneous<br />
measurement), the sensors are i<strong>de</strong>al for<br />
movingandoscillatingtargets.<br />
FlatnessmeasurementofICpins<br />
Toachievethebestqualityduringboardassembly,allICpins<br />
mustlie inone plane. Inmo<strong>de</strong>rn<br />
automatic placement systems<br />
the ICs are therefore measured<br />
directly before placement. The<br />
tiny light spot diameters enable<br />
the measurement of the finest<br />
pingeometries.<br />
Shapeconformanceon<br />
aluminumwheels<br />
After casting, aluminum wheels<br />
are measured for a range of<br />
features, e.g. hub <strong>de</strong>pth, roundness,<br />
bulging, etc., before being<br />
processedfurther.<br />
Surfaceprofiling<br />
Due to the small measuring spot and<br />
RTSC(Real-TimeSurfaceCompensation),<br />
the LDS 85 is excellent for the high<br />
precision mapping of any target<br />
regardless of its reflectivity, angle, shape<br />
andcolor.<br />
Partpositioninginproductionlines<br />
Forautomatedprocessing stagesoncarbodiesorvehicles<br />
an exact <strong>de</strong>termination of the<br />
position relative to the<br />
processing tool is necessary<br />
(drilling, punching, fitting subassemblies).<br />
Due to the<br />
adjustable exposure time and<br />
the real-time surface<br />
compensation, the series LDS<br />
85 is particularly suitable for the<br />
highprecisionacquisitionofhighlyglossysur-faces.<br />
<strong>Distance</strong>ofvehicletoroadsurface<br />
In road tests pitching and rolling movements, spring<br />
compression during braking and other quantities are<br />
measured with LDS 85 sensors. The series LDS 85 is<br />
particularly suitable here due to<br />
the compact construction and<br />
the possibility of supplying the<br />
sensor from the vehicle power<br />
supply(11...30VDC).Forthese<br />
applications there are special<br />

SynchronousdatarecordingwiththeIF2004<br />
With the IF2004 PCI interface card, which is available as an<br />
accessory, the data from up to four sensors can be<br />
synchronously read via aFIFO memory.Readings from an<br />
enco<strong>de</strong>rorlinearmeasurementsystemasthefourthchannel<br />

Analoganddigitaloutputs<br />
Withtwoanalogueoutputsignals0...10Vand4...20mAas<br />
well as the serial RS422 interface, the LDS 85 range of<br />
sensorsfulfilsallinterfacerequirements.Thebaudrateofthe<br />
RS422 can be set in standard steps from 9,600 to 115,200<br />
baud. This allows adirect communication to aPLC or any<br />
other host. In addition the dataformat of the serial interface<br />
canbechangedfrombinarytoASCIIcharacteroutput.<br />

Adjustablefilterfunctions<br />
Toachieve the best results for each application,<br />
three different filter functions can be applied to the<br />
measurementresults.<br />
The recursive mean works similar to an analog<br />
low-passfilter.<br />
The moving average enables ahigh dynamic<br />
responseevenwithfiltering.<br />
The median filter is especially suitable for<br />
surfaceswithrandomfalsereadings.<br />
