Laser safety notices

Laser diode of the transmitter – laser class 1M
INVISIBLE LASER RADIATION – CLASS 1M LASER PRODUCT
Do not expose users of telescopic optics!
The device satisfies the requirements of IEC/EN 60825-1:2014 safety regulations for a product
of laser class 1M and complies with 21 CFR 1040.10 except for conformance with IEC 60825-1
Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019.
Ä Looking into the beam path for extended periods using telescope optics may damage the
eye's retina. Never look using telescope optics into the laser beam or in the direction of re-
flecting beams.
Ä CAUTION! Use of controls or adjustments or performance of procedures other than speci-
fied herein may result in hazardous light exposure.
The use of optical instruments or devices (e.g., magnifying glasses, binoculars) with the
product will increase eye danger.
Ä Observe the applicable statutory and local laser protection regulations.
Ä The device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
The device emits invisible laser radiation with a wavelength of 785 nm (device with designation
"Frequency F3") or 852 nm (device with designation "Frequency F4") through the laser aperture of the
optical window. The beam spread of the beam cone is ≤ 1° (± 0.5°).
The power density distribution in the light spot is homogeneous; there is no elevation of power density in
the center of the light spot. The average emitted laser power of the device is < 12 mW. For transmission of
the data, the emitted laser radiation is amplitude modulated (on-off keying). Pulses and pulse pauses of the
emitted laser light are between 8 ns and 32 ns long. The laser power emitted during the pulses is < 24 mW.
