IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050,
Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a
rate of 14 to 16 liters/min.
The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0°, 30°,
60°, and 90° while rotating the test piece on a horizontal plane.
For reflectors and mounting brackets refer to Accessories.

Precautions
!
Warning
This product is not designed or rated for directly or
indirectly ensuring safety of persons. Do not use it for
such a purpose.
Precautions for Correct Use
Do not use the Sensor in any atmosphere or environment that
exceeds the ratings.
Do not install the Sensor in the following locations.
(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations where the Sensor may receive direct vibration or
shock
!
Caution
Do not use the product with voltage in excess of the
rated voltage. Excess voltage may result in malfunc-
tion or fire.
Never use the product with an AC power supply.
Otherwise, explostion may result.
Connecting and Mounting
(1) The maximum power supply voltage is 30 VDC. Before turning
the power ON, make sure that the power supply voltage does
not exceed the maximum voltage.
(2) Laying Sensor wiring in the same conduit or duct as high-volt-
age wires or power lines may result in malfunction or damage
due to induction. As a general rule, wire the Sensor in a sepa-
rate conduit or use shielded cable.
(3) Use an extension cable with a minimum thickness of 0.3 mm
2
and less than 100 m long.
(4) Do not pull on the cable with excessive force.
(5) Pounding the Photoelectric Sensor with a hammer or other
tool during mounting will impair water resistance.
(6) Mount the Sensor either using the bracket (sold separately) or
on a flat surface.
(7) Be sure to turn OFF the power supply before inserting or re-
moving the connector.
When cleaning the product, do not apply a high-pres-
sure spray of water to one part of the product. Other-
wise, parts may become damaged and the degree of
protection may be degraded.
High-temperature environments may result in burn
injury.
Precautions for Safe Use
The following precautions must be observed to ensure safe
operation of the Sensor.
Sensitivity adjustment
Setup is completed by teaching the sensor to the reflector (with-
out object). For transparent object detection or detection of very
small objects: Turn the sensitivity adjuster slowly from minimum
to maximum and stop at the position where the output LED
changes state (orange LED turns from on/off to off/on) and green
stability LED is on. For opaque object detection: Set the sensitiv-
ity adjuster to maximum. Confirm correct operation by testing
stable detection with reference object.
Operating Environment
Do not use the Sensor in an environment where explosive or
flammable gas is present.
Connecting Connectors
Be sure to hold the connector cover when inserting or removing
the connector. Be sure to tighten the connector lock by hand;
do not use pliers or other tools. If the tightening is insufficient, the
degree of protection will not be maintained and the Sensor may
become loose due to vibration. The appropriate tightening torque
is 0.39 to 0.49 N·m for M12 connectors.
Cleaning
Never use thinner or other solvents. Otherwise, the Sensor sur-
face may be dissolved.
Power Supply
If a commercial switching regulator is used, ground the FG (frame
ground) terminal.
Load
Do not use a load that exceeds the rated load.
Rotation Torque for Sensitivity Adjustment
Adjust with a torque of 0.05 Nm or less.
Power Supply Reset Time
The Sensor will be able to detect objects 100 ms after the power
supply is tuned ON. Start using the Sensor 100 ms or more after
turning ON the power supply. If the load and the Sensor are con-
nected to separate power supplies, be sure to turn ON the Sensor
first.
Environements with Cleaners and Disinfectants
(e.g. Food Processing Lines)
Do not use the Sensor in environments subject to cleaners and
disifectants. They may reduce the degree of protection.
Modifications
Do not attempt to disassemble, repair, or modify the Sensor.
Turning OFF the Power Supply
Output pulses may be generated even when the power supply is
OFF. Therefore, it is recommended to first turn OFF the power
supply for the load or the load line.
Outdoor Use
Do not use the Sensor in locations subject to direct sunlight.
Cleaning
Do not use thinner, alcohol, or other organic solvents. Otherwise,
the optical properties and degree of protection may be degraded.
Load Short-circuit Protection
This Sensor is equipped with load short-circuit protection, but be
sure to not short circuit the load. Be sure to not use an output cur-
rent flow that exceeds the rated current. If a load short circuit oc-
curs, the output will turn OFF, so check the wiring before turning
ON the power supply again. The short-circuit protection circuit will
be reset. The load short-circuit protection will operate when the
current flow reaches 1.8 times the rated load current. When using
a capacitive load, use an inrush current of 1.8 times the rated load
current or higher.
Surface Temperature
Burn injury may occur. The Sensor surface temperature rises de-
pending on application conditions, such as the surrounding tem-
perature and the power supply voltage. Use caution when
operating or washing the Sensor.
Water Resistance
Do not use the Sensor in water, rainfall, or outdoors.
