Safety Precautions
General Precautions
• This product is only intended to detect objects. Do not use this
product for the purpose of protecting a human body or a part of
the human body.
WARNING
NOTICE
• This product is not intended for use as an explosion-proof product. 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 product may explode or burn if an AC voltage is applied.
• Do not wire the amplifier line along with power lines or high-tension 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 displayed value may not be the same on all units.
Safety Precautions on Laser Product
• This product uses a semiconductor laser for the light source.
• Use of controls or adjustments or performance or procedures
other than those specified herein may result in hazardous radiation exposure.
WARNING
FDA (CDRH) Part 1040.10
• Follow the instructions mentioned in this manual. Otherwise,
injury to the human body (eyes and skin) may result.
Precautions on Class 1 laser products
• Do not stare into the beam.
• Do not disassemble this product. Laser emission from this
product is not automatically stopped when it is disassembled.

Reference
Laser Transmission OFF input
When the laser transmission OFF input is set for external input, the laser
transmission can be stopped by turning the external input ON (2 ms or
longer). The transmission is stopped while the external input is ON. Once
the external input is turned OFF, the laser transmission will resume within
20 ms.

Connecting multiple amplifiers
Up to 16 expansion units can be connected to 1 main unit. Note, however, that the 2output type is considered as 2 expansion units.
This method applies only when using the main unit independently. If the
main unit is connected with an expansion unit(s), use the method of mounting on a DIN rail.
Mount the amplifier on the amplifier mounting bracket (OP-73880, sold separately),
using the same manner as "Mounting on a
DIN rail".
Secure the unit with two M3 screws as
shown in the illustration.
Mount on DIN rail and install on metal surface when connecting

Point
• Contact your nearest KEYENCE office when connecting a unit
other than the N-bus (KEYENCE’s wire-saving system) compatible
sensor amplifier, including LV-N10 Series, or the NU Series communication module.
• Turn the power off before connecting multiple expansion units.
• Do not touch the expansion connector with your bare hands.
• When using the LV-N10 Series as a main unit, use the products
within the expansion unit’s power voltage range if the power voltage range of the expansion unit is narrower than the LV-N10
Series.
Remove the protection covers from the main unit
1
and expansion unit(s).
Mount the main unit and expansion unit(s) on the
2
DIN rail.
Slide the main unit and expansion unit(s) together.

Engage the 2 claws of the expansion unit with the
recesses on the main unit side until you hear/ feel
a click.
Attach the separately sold end units (OP-26751: a

Adjusting the Sensitivity
In this manual, the value at which the sensor amplifier's ON/OFF output switches is
expressed as the "setting value". The process of adjusting the setting value is expressed
as "adjusting the sensitivity". This section explains the method of adjusting the sensitivity.
List of Sensitivity Adjustment Methods
The methods of adjusting the LV-N10 series sensitivity is largely classified into 2 types.
(1) Preset
At the same time as adjusting the sensitivity, the received light intensity can be
calibrated to "100.0" or ".0" using simple operations.
This method can decrease the variation of the received light intensity depending on
the contents of the detection and the workpiece, and is useful for predictive
maintenance.
However, this is not suitable for when difference in received light intensity varies little
with or without a workpiece, such as when detecting a transparent workpiece.
(2) Calibration
The sensitivity can be adjusted with simple operations. The received light intensity is
not compensated.
This method is used to adjust without calibrating the received light intensity, or when
highly accurate detection is required.
Calibration can be performed in the preset state.

The sensitivity is adjusted just by
pressing and holding the [PRESET]
button when a workpiece is absent.
The states at which to display
"100.0" and ".0" can be set randomly.
The sensitivity can be calibrated
using a workpiece which moves at
high speed.
The setting can be established just
by pressing the [SET] button on ce
when a workpiece is present and
absent.
The sensitivity can be calibrated
using a workpiece which moves at
high speed.
This setting prevents malfunctions
even when using in an easily contaminated environment.
A setting suitable for positioning can
be made.
This is useful for calibrating from an
external device, such as a PLC.
