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.

(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.
For extending wires, use a cable of 0.3mm

2

 min. and

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.

(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.

(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.

(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.

(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.

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

3 .   Set the MODE selector to the  RUN  position.
4 .   Using the RUN MODE selector, select L-ON or D-ON. 

L-ON: Output is given by the background.
D-ON: Output is interrupted by the background.

2. Direct the sensor toward the background and hold

down the  SET  button. All the THRESHOLD indicators
(red) light up. Then release the SET button.

When the teaching is acceptable, all the DISTANCE 

indicators (green) light up.

If the teaching is rejectable, all the THRESHOLD 

in-dicators (red) start flashing. Re-arrange the sensor.
Repeat steps 2 to 3 again.

1.  Set the NORMAL/ZONE selector to the ZONE posi-

tion.

Set the Mode Selector  to   TEACH.
Set the selector to RUN to complete the distance setting.

The following settings can also be made.
To set the sensor's distance differential to the maximum 
distance, see "Maximum distance setting".
To set it to the minimum distance, see "Minimum distance 
setting".

Note 1: Background distance.

In case of Normal one-point teaching and Zone 
one-point teaching, the distance between the 
sensor and background is more than Xmm.

Note 2: In case the setting distance is more than 

150mm, the maximum detecting distance 
de-pend on color of the object. Before using,
make sure if it works. (Type E3G-L3

)

Be also careful when a detectable object has quite 
different colors or is made of different materials.

(7)  Be sure to place the photoelectric switch so that 

its  sensing face be parallel with (not tilted against) a 
detect-able object.

DISTANCE SETTING (TEACHING)

 

Zone one-point teaching

 

Normal one-point teaching

1 .   Set the NORMAL/ZONE selector to the NORMAL 

position.

2.   Direct the sensor toward the background and hold down 

the  SET  button.

All the THRESHOLD indicators (red) light up.

If the teaching is rejectable, all the THRESH 
indicators (red) start flashing.

3 .   zSet the MODE selector to the RUN  position.
4 .   Using the RUN MODE selector, select L-ON or D-ON.

L-ON: Output is given between the background and 

the sensor.

D-ON: Output is interrupted between the background 

and the sensor.

 

Minimum distance setting

1.   Set the NORMAL/ZONE selector to the  NORMAL

position.

2.   Set the UP/DOWN selector to the DOWN (

) position.

3.  Hold down the SET button for 3 seconds or longer.

All the THRESHOLD indigators (red) light up.

To set the sensor's distance differential to the minimum 
distance, take the following steps.

To set the sensor's distance to the maximum distance,
take the following steps.

4. Wait until all the DISTANCE indicators light up. Set

the MODE selector to the RUN position.

5.  Using the RUN MODE selector, select L-ON or D-ON. 

(Refer back to the normal one-point teaching.)

4.   Wait until all the DISTANCE indicators (green) light

up. Set the MODE selector to the RUN position.

5.   Using the RUN MODE selector, select L-ON or D-ON. 

(Refer back to the normal one-point teaching.)

 Normal two-point teaching

1.Set the  NORMAL/ZONE  selector to the   NORMAL 

position.

2.Direct the sensor toward a work and hold down the

SET  button.

All the THRESHOLD indicators (red) light up.

3.  Move the work. Direct the sensor toward the back-

ground and hold down the  SET  button.

When the teaching is acceptable, all the DISTANCE 

indicators (green) light up.

If the teaching is rejectable, all the THRESHOLD 

in-dicators (red) start flashing.

4. When the teaching is accepted, set the MODE selector

to the RUN position. If it is rejected, change the work 
position and distance. Repeat the above steps 3 and 4.

5. Using the RUN MODE selector, select L-ON or D-ON.

After teaching, the threshold can be finely adjusted.
If detection is unstable by difference of color, adjust 
threshould to make detection stable.
1.   Set the MODE selector to the  ADJ  position.
2. In the ADJ mode, specify the adjustment direction

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.

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.
