PRECAUTIONS FOR SAFE USE

Be sure to follow the safety precautions below for added
safety.
( 1 ) Do not use the sensor under the environment with
explo-sive or ignition gas.
( 2 ) Never disassemble, repair nor tamper with the product.
( 3 ) Keep the supply voltage within the specified range.
( 4 ) Do not use the sensor over the rated values.
( 5 ) Do not short-circuit the load. The sensor type has a
load short-circuit protective function, but avoid
keeping it short-circuited for a long time.
( 6 ) Do not use the sensor in the water.
( 7 ) Be careful not to confuse the terminal polarities.

PRECAUTIONS FOR CORRECT USE

( 1 ) Do not use the product under the following conditions.
In the place exposed to the direct sunlight.
In the place where humidity is high and condensa-
tion may occur.
In the place where corrosive gas exists.
In the place where vibration or shock is directly
transmitted to the product.
( 2 ) Connections
Before turning on the power, make sure the supply
voltage is below the maximum voltage level.
Routing the wires of the photoelectric switch with
high potential power lines may cause malfunction or
damage to it because of the inductive effects.
Be sure to route the switch wires separated from the
power lines or though an exclusive conduit.
2
For extending wires, use a cable of 0.3mm
100m max. in length.
( 3 ) Cleaning
Do not use thinner such as alcohol and benzine because it
may damage a product.
( 4 ) Power supply
When using a commercially available switching regula-
tor, be sure to ground the FG (Frame Ground) and G
(Ground) terminals.If this is not done, failure in opera-
tion may happen by switching noise of the regulator.
( 5 ) Function of this sensor will be stable 100ms after turning
on the power supply.
( 6 ) Water-proof
Do not use in the water, rain or outdoor.
( 7 ) Control cover
Tighten the cover screws at the torque of 0.2 to 0.3
N ・ m to keep water-proof.
■ Installation
( 1 ) Position the photoelectric switch so that direct sunlight,
flourescent light, incandescent light and any other
strong rays do not come within the response angle.
( 2 ) Sensors that are installed facing each other may cause
mutual interference. Set them up with their optical axes
not facing each other.
( 3 ) Use 3M screws to secure the unit.
( 4 ) Tighten the casing screws to 0.54 N-m or lower.
● M8 connectors
( 5 ) Before connecting and disconnecting the connectors,
be sure to turn off the power.
( 6 ) In connecting and disconnecting the connectors, be
sure to hold the connector covers.
Setup direction
●
( 7 ) Be sure to place the photoelectric switch so that
its sensing face be parallel with (not tilted against) a
detect-able object.
Sensor
Work
( 8 ) When detecting a glossy object, however, place the
photoelectric switch tilted 5–10° to the glossy object. See
the figure bellow or select Zone one-point teaching.
Glossy object
( 9 ) If there is something mirror-surfaced below the
photo-electric switch, the switch performance may be
adversely affected. Tilt the switch or keep it away
enough from the mirror surface.
Detectable object

In placing the photoelectric switch, pay attention to the
moving direction of a detectable object. See the figure

with the UP/DOWN selector. Each time the SET but-
ton is pressed, the threshold moves up or down. Up to
13 levels can be preset (at Normal one-point, two-point
teaching and Zone one-point teaching).

THRESHOLD indicator light-up in adjusting the sensitivity
Up to 13 levels are adjustable for the normal teaching.
(Up to 5 levels are adjustable for the zone teaching.)
3 . Finally set the MODE selector to the RUN position.
● THRESHOLD and DISTANCE indicator light-up
・ Light-up in the case of distance setting in normal teaching.
The DISTANCE indicators tell the distances that are
re-lative to the thresholds.
Using the UP/DOWN selector and the SET button, the
threshold can be shifted. The distance differential is fixed,
however.
About 21g ・ Light-up in the case of distance setting in zone teaching.
The DISTANCE indicators tell the current distance range
that is relative to the threshold.
Using the UP/DOWN selector and the SET button, the
output ON range can be shifted. The distance differential
is fixed, however.
