Countermeasures to Handle Inductive Noise
4. Insert a plastic insulator of approximately 10 mm between
the Sensor and the mounting base.
Effects of Inductive Noise
• When there is inductive noise in the Sensor mounting frame
(metal), the output of the sensor may be affected. In this case,
ensure that there is no electrical potential difference between
the sensor 0-V terminal and the sensor mounting frame, or put
a 0.47-μF capacitor between the 0-V terminal and the frame.
<Effects when the power supply is turned ON>
(Digital only)
An output pulse may occur when the power supply is turned ON
depending on the power supply and other conditions. Use the
sensor in the stable ready-for-detection state reached in 100 ms
after turning on the power supply.
