CautionsforInstallation
•Install the unit correctly with the usage environment, location, and the designated
•Do NOT impacts with a hard object or excessive bending of the wire lead-out. It may
cause damage the water resistance.
•Do NOT pull the Ø 2.5 mm cable with a tensile strength of 20 N, the Ø 4 mm cable with
a tensile strength of 30 N or over and the Ø 5 mm cable with a tensile strength of 50 N
•When extending wire, use AWG 22 cable or over within 200 m.
•Tighten the installing screws with under 1.47 N m torque.
Safety Considerations
•Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazards.
•᜸symbol indicates caution due to special circumstances in which hazards may occur.
᜸Warning Failure to follow instructions may result in serious injury or death.
01. Fail-safe device must be installed when using the unit with machinery that
may cause serious injury or substantial economic loss. (e.g. nuclear power
control, medical equipment, ships, vehicles, railways, aircraft, combustion
apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or
02.
high humidity, direct sunlight, radiant heat, vibration, impact, or salinity
may be present.
03. Do not disassemble or modify the unit.
04. Do not connect, repair, or inspect the unit while connected to a power
source.
05. Check 'Connections' before wiring.
᜸Caution Failure to follow instructions may result in injury or product damage.
01.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Cautionsduring Use
•Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected
accidents.
•12-24 VDCᜡpower supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
•Use the product, after 0.8 sec of supplying power.
•Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise.
Do not use near the equipment which generates strong magnetic force or high
frequency noise (transceiver, etc.).
In case installing the product near the equipment which generates strong surge (motor,
welding machine, etc.), use diode or varistor to remove surge.
•This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specifications’)
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category II

SettingDistance Formula
Detecting distance can be changed
by the shape, size or material of the
target.
For stable sensing, install the unit
within the 70% of sensing distance.
Setting distance (Sa)
= Sensing distance (Sn) × 70%
