Application Note
・
For optimum performance, allow 15 minutes for the sensor to
warm up.
・
Since the detection distance may change due to the surrounding.
environment or aging, please perform correction and maintenance
on a regular basis.
・
In an operating environment with a temperature change, please set
the sensor with sufficient margin.
・
After the SA1F housing, when transporting or storing under high
temperature environment, please reconfirm the sensing range at
startup.
・
Depending on the use environment, the housing may be
discolored, but performance of the sensor is not affected.
・
When handling, take measures against static electricity and
surges.
・
If the power supply voltage is not stable, malfunction may occur.
