Chapter 4 Requirements for Use
Environmental requirements
Operating
temperature
-20℃ ~ 60℃
storage
temperature
-40℃ ~ 70℃
Working
humidity
5%RH~95%RH (non-condensing)
Static Protection
In the process of unpacking and use, pay attention to anti-static measures, such as using a grounding wrist strap
and grounding the work area .
Thermal Considerations
WSM-QL1601 will emit heat during operation, and in the case of continuous operation at full speed for a long
time, the heat will accumulate to a certain extent . Although WSM-QL1601 can be adapted to work in high
temperature environment, in high temperature environment, it will increase image noise, reduce image quality and
reduce reading performance . Consider the actual use environment to determine whether the heat dissipation design
is appropriate .
When designing, consideration should be given to reserving space for WSM-QL1601 to form natural
convection or forced convection .
Avoid wrapping WSM-QL1601 with insulating materials such as rubber .
Ripple noise
Since the power input of WSM-QL1601 is directly provided to the image sensor and decoding chip, in order to
ensure stable operation, please use the power input with low ripple noise, which is guaranteed not to exceed 50mV
(peak-to-peak) .
Optical correlation
Scanning area distribution
