those above Effect of noise. Effect of noise is excessive. If other devices using the same
power supply generate noise, do
not share the same power supply
with other devices and use it as
that exclusive for the safety
component.
The inductive noise tends to be
induced especially if the power
line and the power supply line are
arranged in parallel. Arrange the
exclusive power supply near the
light curtain or lay the power line
away from the power line.
If the power supply for operation
is located near the power supply
and it uses the same ground, it is
subject to the influence of
common mode noise from the
ground. Separate the grounding
point or use it as the exclusive
ground.
