FEATURES
Various outputs selectable
Two outputs are provided for the DC
type, NPN and PNP output, so that a
single photoelectric sensor can match
either of both polarities. The output sec-
tion of the AC/DC type is compact 1
Form A relay contact rated 1 A, 250 V
AC and 2 A, 30 V DC (resistive).
Wide operating voltage range
The DC type operated by 12 to 24 V
DC and the AC/DC type by 12 to 240 V
DC or 24 to 240 V AC, 50/60 Hz power
supply. This allows operation voltages
world wide.
Protection circuit incorporated
Protection circuit is provided for the
transistor output type (DC type) against
erroneous reverse wiring and short-cir-
cuit.
Accurate detection, regardless of-
colors, materials, or shapes
Area reflective type permits the detec-
tion of white and black targets at almost
the same distance. Also targets with
mixed colors, that are difficult to detect
with standard diffuse reflective type,
can be detected.
Unaffected by background objects
Area reflective type does not detect
objects beyond the set range.
Polarization filter;
Standardized for Retroreflective
type,
even a shiny target detectable.
Optionally for Thru-beam type,
cross-talk prevention function is avail-
able.
Immersion protected construction
(equivalent to IEC IP67)
Rotary connector types available for
easy maintenance and installation
maintenance
Sensitivity adjuster and indication
LED are equipped
Thru-beam type can detect even a
translucent target by lowering the sen-
sitivity.
Light-ON/Dark-ON selectable
APPLICATIONS
Detection of small to large targets.
Large product assembly lines, automat-
ed vertical warehouses, personnel
detection, etc.

Distance adjustment for
Trigonometric area reflective type
1) Point the detection face of the photo-
electric sensor towards the targets
direction and temporarily fasten.
2) Set the DISTANCE adjuster to maxi-
mum position (FAR). If the LIGHT indi-
cator LED does not turn ON at this
position without surroundings towards
detection direction, then recognize this
position as “FAR” one. If the LIGHT
indicator LED turns ON at this position
detecting surroundings, turn the DIS-
TANCE adjuster slowly counterclock-
wise to find a FAR position where the
LIGHT indicator LED turns OFF.
3) Place a target at the detection posi-
tion and set the DISTANCE adjuster to
its minimum setting NEAR and slowly
turn it clockwise and note the LIGHT
indicator LED turns ON.
The minimum position at which the
LIGHT indicator LED turns ON is the
NEAR position.
4) Set the DISTANCE adjuster to the
middle of the two positions found in 2)
and 3) above.
5) Fasten the photoelectric sensor.
Mount securely so that the photoelec-
tric sensor is not shifted from alignment
by vibrations or impact.
Notes:
1. If the ADJUST indicator LED does not
turn ON in step 4), or if such a operation
range acquainted by above 2) or 3) is less
than 2 graduations, either change the posi-
tion of the detection surface and repeat
steps 1) to 4), or adjust external factors such
as ambient temperature variations, position
of target, etc.
2. The detection distance varies only slightly
with the color of the target.
However, if the target has an extremely low
reflection factor (dull black rubber), detection
may not be possible, or if the target has an
extremely high reflection factor (mirrors,
glass, glossy paper and other specular
reflection targets), adjustment of the detec-
tion distance may not be possible. Use the
actual target to check operation.
3. Please be careful not to apply excessive
torque to the DISTANCE adjuster and the
LIGHT-ON/DARK-ON selector switch.
Sensitivity adjustment for
Diffuse reflective type
1) Facing the detection face in the
detection direction, temporarily fasten
it.
2) Set the SENSITIVITY adjuster to its
maximum position (MAX.). If the OPE.
indicator LED does not turn ON at this
position without surroundings towards
detection direction, then recognize this
position as “MAX.’’ one. If the OPE.
indicator LED turns ON at this position
detecting surroundings, turn the SEN-
SITIVITY adjuster slowly counterclock-
wise to find a MAX. position where the
OPE. indicator LED turns OFF.
3) Place a target at the detection posi-
tion, and further turn the SENSITIVITY
adjuster counterclockwise to find the
position where the OPE. indicator LED
goes out.
4) Fasten the SENSITIVITY adjuster at
the middle point between the positions
selected in steps 2) and 3).
5) Fasten the photoelectric sensor so
securely as not to be displaced by
vibration or shock.
Notes:
1. Since the detectable distance depends on
the material, color, size, shape and direction
of targets, and the environmental conditions,
check and adjust it using an actual target.
2. If the STAB. indicator LED does not come
ON in step 4), reposition the detection face
and repeat the procedure of steps 1) to 4) or
pay attention to other factors such as ambi-
ent temperature variations, position of target,
etc.
3. Please be careful not to apply excessive
torque to the SENSITIVITY adjuster and the
LIGHT-ON/DARK-ON selector switch.
Light axis adjustment for
Retroreflective type
1) Temporarily mount the reflector and
the photoelectric sensor in proper align-
ment.
2) Move the photoelectric sensor left
and right, up and down to find a posi-
tion in the center of the range in which
the OPE. indicator LED is ON.
3) Check the photoelectric sensor’s
operation when a target passes the car-
rying path.
4) If it does not operate, adjust the sen-
sitivity.
5) Affix the reflector and photoelectric
sensor in position firmly so that vibra-
tion or shock must not cause the light
beam axis to shift out of alignment.
Notes:
1. If the STAB. indicator LED does not
come ON in step 3), reposition the
reflector and repeat steps 1) to 3) or
pay attention to other factors such as
ambient temperature variations, posi-
tion of target, etc.
2. Please be careful not to apply exces-
sive torque to the SENSITIVITY
adjuster and the LIGHT-ON/DARK-ON
selector switch.
Light axis adjustment for
Thru-beam type
1) Swing the projector and receiver to
left and right, and up and down to find a
position around the middle of the OPE.
indicator LED’s ON range, and then
secure them. At this time, confirm that
the STAB. indicator LED is lit.
2) Sensitivity adjusting makes detection
possible of translucent targets.
For translucent targets, the SENSITIVI-
TY adjuster is turned to the position
where the target can be detected.
Note:
1. If the STAB. indicator LED goes out dur-
ing operation, the sensor detection does not
work any longer. Check the situation and
adjust the sensitivity again.
2. Please be careful not to apply excessive
torque to the SENSITIVITY adjuster and the
LIGHT-ON/DARK-ON selector switch.

CAUTIONS
1. Operating Environment
1) The sensor should be used in an
ambient temperature range of –25 to
+60°C –13 to +140°F (DC type) or –25
to +55°C –13 to +131°F (AC/DC type)
2) Use an operating voltage in the
range of 9.6V to 30V DC for the DC
types and 21.6V to 264V AC or 10.8V
to 264V DC for the AC/DC types.
3) The light intensity on the receiver
surface should be less than 3,000 lux
for an incandescent light source and
less than 10,000 lux for sunlight.
4) Use a surge absorber as the internal
circuit may be damaged if external
surge voltages exceed 500V (for DC
type)/4,000V (for AC/DC type)
[±(1.2T50)µs single polarity full-wave
voltage].
5) Avoid use in locations with high con-
centrations of steam, dust , corrosive
gases, etc.
6) Use a load relay with a rated operat-
ing voltage of 12V DC or 24V DC for
the DC types. The voltage applied to
the load relay is the operating voltage
of the photoelectric sensor minus the
internal voltage drop (maximum 1.2V
NPN side, 2V PNP side). Voltage fluc-
tuations should be taken into account.
7) The output circuit of the DC type
contains a short-circuit protection cir-
cuit. However, be sure the inrush cur-
rent does not exceed the maximum out-
put current capacity for proper detec-
tion.
8) The sensor is immersion protected
type, but this does not mean that it can
be used in water or where there is
direct impingement or rain for detecting
targets.
2. Wiring
1) Check all wiring before applying
power since incorrect wiring may dam-
age the internal circuit.
2) Ground the frame ground (FG) termi-
nal and ground (G) terminal when using
a commercially available switching reg-
ulator. If a ground is not connected,
switching noise from the power supply
may result in faulty operation.
3) Wire 0.3 mm2.0005 inch2AWG22 or
larger should be used for wiring up to a
length of 100 m 328 ft.
4) Please use a fitting cable for wiring
the connector type sensor to maintain
the characteristic of protection struc-
ture.
5) Tighten the connector with a maxi-
mum torque of 0.8 N·m {8.2 kgf·m,
7.09 lbf·in}.
3. Detector
1) Keep the detector surface clean as
excessive dust or dirt on the detector
surface will decrease the margin of the
sensing distance.
2) The front surface of the lens and
case are made of polycarbonate resin
(but the front surface of Retroreflective
type is made of polymethylmethacry-
late). Although it withstands water,
weak acids and alkalines, aliphatic
hydrocarbons, and oils and fats, it is not
resistant to ketones, esters, halogenat-
ed hydrocarbons and aromatic hydro-
carbons.
4. Moving Direction of the Target
(for Trigonometric area reflec-
tive type)
Take care with the mounting direction
of the photoelectric sensor with respect
to the moving direction of the target.
5. Other cautions
1) When using the optional mounting
bracket, tighten the mounting screws
with a maximum torque of 0.8N·m
{8.2 kgf·cm, 7.09 lbf·in}. If the optional
mounting bracket is not used, mount
the sensor on a flat surface.
2) For the use UL and CSA approval
KA1 photoelectric sensor, the connec-
tor and cable shall also bear the UL
and CSA approval to use with.
3) The connector on the sensor’s body
side has a rotary structure.
Be sure to rotate the connector accord-
ing to the arrow mark on the sensor.
The direction of connector must be
determined before the sensor is
mounted.
4) Rotate the connector with a maxi-
mum torque of 0.2 N·m{2 kgf·m,
1.77 lbf·in}.
5) Handling for polarization filter and
slit.
*Rotating the connector in the reversed direction
will damage the rotary structure.
