Distance from surrounding metal
• As metal around the sensor may affect the sensing
performance, pay attention to the following points.
Influence of surrounding metal
• T he surrounding metal will affect the sensing performance.
Keep the minimum distance specified in the table below.

Embedding of the sensor in metal
• S ensing range may decrease if the
sensor is completely embedded
in metal. Especially for the non-
shielded type, keep the minimum
distance specified in the right table.

Note: With the non-shielded type, the sensing
range may vary depending on the
position of the nuts.
Mutual interference
• When two or more sensors are installed in parallel or face
to face, keep the minimum separation distance specified
below to avoid mutual interference.

Wiring
• Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator, ensure
that the frame ground (F.G.) terminal of the power supply is
connected to an actual ground.
• Ensure that an isolation transformer is utilized for the DC power
supply. If an autotransformer is utilized, the main body or power
supply may be damaged.
• If the used power supply generates a surge, connect a surge
absorber to the power supply to absorb the surge.
• In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this product, connect the frame
ground (F.G.) terminal of the equipment to an actual ground.
• Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
• Damage or burnout may result in case of short circuit of load or
miswiring.
• Make a cable length as short as possible to lessen noise pickup.
Others
• Our products have been developed / produced for industrial use
only.
• Avoid using a product where there is excessive vapor, dust or
corrosive gas, or in a place where it could be exposed directly to
water or chemicals.
• Take care that the sensor does not come in direct contact with
water, oil, grease or organic solvents, such as, thinner, etc.
• Do not use in an environment containing infammable or explosive gases.
• Never disassemble or modify the product.
