Laser class 2
BOD 21M photoelectric distance sensors meet the
requirements of safety standard IEC 60825-1:2007 for
class 2 laser products. In addition, they meet the directives
as per U.S. 21 CFR 1040.10 and 1040.11 for class II laser
products with the exception of the deviations described in
the document "Laser Notice No. 50" dated June 24, 2007.
Radiated power
The BOD 21M uses a laser diode with a low output in the
visible light spectrum. The emitted wavelength is 650 nm.
The peak output of the laser beam is 1.2 mW. The
measured radiated power at a distance of 20 cm through
an aperture of 7 mm and over an average of 1000 s is
lower than 1 mW as per the specifications for
CDRH class II.
More detailed information on the guidelines,
approvals, and standards is included in the
declaration of conformity.
Safety
Intended use
BOD series photoelectric distance sensors are intelligent,
adjustable sensors with a CCD element for measuring
distances and were developed only for applications in
accordance with NFPA 79 (machinery with a maximum
supply voltage of 600 volts). Application examples include:
– Distance measurement
– Contour determination
– Stack positioning
– Fill level measurement
– Packet conveying machines
Non-approved use
These sensors may not be used in applications where
personal safety depends on proper function of the devices
(not designed in accordance with EU Machinery Directive).
Examples of non-approved use include rooms with
explosive atmospheres and operation for medical
purposes.

Safety (continued)
Opening the sensor or non-approved use are not
permitted and will result in the loss of warranty and liability
claims against the manufacturer.
General safety notes
Installation, startup, and maintenance may only be
performed by trained specialists with basic electrical
knowledge. Qualified personnel are those who can
recognize possible hazards and institute the appropriate
safety measures due to their professional training,
knowledge, and experience as well as their understanding
of the relevant conditions pertaining to the work to be
done.
Repairs may only be performed by the manufacturer or an
authorized representative.
Do not attempt to make changes to the device or to
modify it in any way.
The operator is responsible for ensuring that local safety
regulations are observed.
In particular, the operator must take steps to ensure that a
defect in the sensor will not result in hazards to persons or
equipment.
If defects and unresolvable faults occur in the sensor, it
should be taken out of service and secured against
unauthorized use.
Laser protection regulations
The emitter features a class 2 red laser as
per EN 60825-1 (2007/03).
DANGER
Eye injuries
Looking into the light beam over an extended period of
time can damage the retina beyond repair.
► Never look directly into the light beam!
► Do not aim the BOD 21M laser beam at people!
► When assembling and aligning the BOD 21M,
prevent laser beam reflections due to reflective
surfaces!
Use of photoelectric instruments or devices in
conjunction with the device increases the risk of damage
to the eyes!
► Observe all relevant legal and operational
requirements with regard to eye protection from laser
radiation in accordance with the latest version of
EN 60825-1!
The glass front panel is the only opening through which
laser radiation can escape from the device. The BOD
housing is sealed and does not feature any components
that have to be set or maintained by the user. The device
must not be altered or changed in any way! Breaking the
seal renders the warranty null and void!
File no.
