Eye safety
The transmitter device emits light with a wavelength of
650 nm (red). This product is designed to avoid damage to
the unprotected eye. To indicate the classification of the
light source, a label as depicted in figure 10 can be used.
However these labels are not mandatory on the product
according to IEC 60825 version 1.2 paragraph 1.1.

Temperature Measuring Point GND PIN
max. Temp. : Tcase max = 105° C
Maximum Temperature at FOT
The maximum abient temperature must not exceed 95° C.
To guarantee the reliability of the AFBR-1012 transmitter
and AFBR-2012 receiver the operation temperature has
to be determined at a defined measurement point at the
GND pin of the transmitter.
The maximum temperature at this particular measure-
ment point for an operating MOST transmitter must not
exceed Tcase,max = 105° C. This temperature value is veri-
fied by measurements during HTOL qualification test.
The receiver has a lower operation temperature than the
transmitter and therefore it is not necessary to consider
the receiver temperature.
The temperature measurement point is defined in the
center of the AFBR-1012 GND pin dambar as shown in
Figure 8.
