Laser Description and Safety Information
CAUTION:
Return defective units to the manufacturer.
Use of controls or adjustments or performance of procedures other than those specified herein
mayresultinhazardousradiationexposure.
Donotattempttodisassemblethissensorforrepair.Adefectiveunitmustbereturnedtotheman-
ufacturer.
Class 2 Laser Models
CAUTION:
Never stare directly into the sensor lens.
Laserlightcandamageyoureyes.
Avoid placing any mirror-like object in the beam. Never use a mirror as a retroreflective target.

For Safe Laser Use - Class 2 Lasers
Donotstareatthelaser.
Donotpointthelaserataperson’seye.
Mountopenlaserbeampathseitheraboveorbeloweyelevel,where
practical.
Terminate the beam emitted by the laser product at the end of its useful
path.
Reference IEC 60825-1:2007, Section 8.2.
Class 2 Lasers
Class 2 lasers are lasers that emit visible radiation in the wavelength range from
400nmto700nm,whereeyeprotectionisnormallyaffordedbyaversionre
sponses,includingtheblinkreflex.Thisreactionmaybeexpectedtoprovideade
quate protection under reasonably foreseeable conditions of operation, including
theuseofopticalinstrumentsforintrabeamviewing.
FDA (CDRH) warning label (Class 2)
Class 2 Laser Safety Notes
Lowpowerlasersare,bydefinition,incapableofcausingeyeinjurywithinthedu
ration of a blink (aversion response) of 0.25 seconds. They also must emit only
visible wavelengths (400 to 700 nm). Therefore, an ocular hazard may exist only
if individuals overcome their natural aversion to bright light and stare directly into
thelaserbeam.

The remote input provides limited programming options and is Active Low by default. For Active Low, connect the gray input
wiretoground(0VDC),witharemoteswitchconnectedbetweenthewireandground.TousetheActiveHighfunction,con-
figure the sensor for Active High using the buttons on the sensor, then connect the gray input wire to V+ (12 to 30 V DC).

Window and Midpoint Example

12 mA
(500 mm) (700 mm)
(600 mm)
Midpoint
The Midpoint TEACH uses both the window size and the 12 mA
(5 V) setpoint to determine the actual measurement window. For
example, a window of 200 mm with a 12 mA (5 V) setpoint of 600
mm places the measurement window from 500 mm to 700 mm.
To use the Midpoint TEACH:
The Analog Output Midpoint TEACH and the Discrete Output
MidpointTEACHareindependentsettings(see"Midpoint
TEACH" on page 26).
WindowSize
TheA_OUT›TchMid›WndSizeoptionsetsthewindowsizethattheMidpointTEACHusestosetthe4mA(0V)and20mA
