Safety instruction
Laser safety
•
The laser diode installed in the OWLF emits visible red laser lights. This
laser belongs to the Class 2 laser standard specified by the IEC 60825-1
/ 2001. It also complies with 21 CFR 1040.10 and 1040.11 except for
deviation pursuant to laser notice No. 50, July 2001.
•
Max. average output power < 1 mW
•
Laser radiation, do not stare into beam
•
To avoid uncontrolled laser exposure we recommended stopping the
beam with a matte object.
•
For laser safety reasons, the voltage supply of the sensors must
be turned off when the whole system or the machine is turned off.
•
Safety concept information and limiting parameters as published in
the sales documentation apply at all times.

Introduction
The latest generation of laser distance sensors are setting new standards in terms of speed and
performance. The short response time (300…900
µ
s) makes it possible to measure small and fast
moving objects up to 600 mm away and 0.3...2.7ms up to 1000 mm away. The advanced teach-in
function allows arbitrarily configuring the measuring range between the default limits in order to
increase the resolution. This allows the complete output swing of 4 – 20 mA and 0 – 10 V to be
mapped on the new range.
The alarm output switches on as soon as the sensor receives no usable signal or as soon as the
object is outside the measuring range.
The sync. output allows the sensor to synchronize the measurement or to use several sensors in a
non-synchronous mode when they would normally interfere optically or to synchronize sensors to a
machine clock or pulse.
The distance measurement is based on the triangulation principal. The use of a photodiode array as
the receiver and the intelligence of a high performance microcontroller produce measuring results
that are almost independent of object colors and just a very small linearity error in the analog output
signal.
The rugged sensor has a metal housing with a front cover made of glass. The 90° rotating connecter
allows wiring the sensor from the bottom or the rear .
