• This product is only intended to detect object(s). Do not use
this product for the purpose of protecting a human body or a
part of the human body.
• This product is not intended for use as an explosion-proof prod-
uct. Do not use this product in a hazardous location and/or
potentially explosive atmosphere.
• This product uses DC power. Do not apply AC power. The prod-
uct may explode or burn if an AC voltage is applied.
• Do not wire the amplifier line along with power lines or high-ten-
sion lines, as the sensor may malfunction or be damaged due to
noise.
• When using a commercially available switching regulator,
ground the frame ground terminal and ground terminal.
• Do not use the LV-N10 series outdoors, or in a place where
extraneous light can enter the light-receiving element directly.
• Due to individual dispersion characteristics and the difference
in sensor head models, the maximum sensing distance or dis-
played value may not be the same on all units.
