LV Series-IM_E

•

To extend the amplifier cable length, use a cable that has a crosssectional area of

at last 0.3 mm

. Limit the length of cable extensions to 100 m. (For further

information on connecting several units contact KEYENCE)

•

Placing the amplifier cable together in the same conduit with power lines or high
voltage lines may cause detection errors due to interference or sensor damage.
For this reason, always isolate the amplifier cable from these lines.

•

If using a commercial switching regulator, make sure to ground both the frame
ground terminal and ground terminal.

•

Do not use the LV Series outdoors, or in any location where extraneous light can
directly enter the light receiving surface.

•

At the maximum sensitivity setting, detection distance may vary somewhat due to
slight differences in the characteristics of individual units.

•

Improper wiring may cause the amplifier to become hot or alter sensitivity. (Input/
Output Circuit Diagram: page 7)

•

Do not use connectors for sensor head-to-amplifier connections more than 100
times.

•

Displayed values may vary due to surrounding conditions (e.g. temperature
changes, dust)

Cautions on using the LV-H62/H62F/H67
•

Use FINE mode when there are any white or mirror-surfaced objects near the
sensor head.

•

When the output is unstable in standard 1 mode (Std), change the detection mode
to standard 2 (Std2).

Reflector
•

The values on the received light intensity display may vary depending on the
surface condition of the reflector.

•

Use the exclusive bracket (optional LV-B101, LV-B102, LV-B301, LV-B302) to
mount the sensor. Adjust the light axis of the transmitter and receiver in both the
vertical and horizontal directions without any target in the detection area. Then,
mount the sensor while maximizing the value displayed on the amplifier. (Adjust
the light axis so that the transmitter beam is at the center of the receiver block)

•

When mounting the sensor, mount the transmitter and receiver so that their sides
on which the indicator is mounted face the same direction.
