Mounting

• The tightening torque should be under the value given

below.

PRECAUTIONS FOR PROPER USE

Wiring

Others

• 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.

• 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.

Distance from surrounding metal

•

As metal around the sensor may affect the sensing

performance, pay attention to the following points.

Influence of surrounding metal

•

The surrounding metal will affect the sensing performance.

Keep the minimum distance specified in the table below.

Embedding of the sensor in metal

•

Sensing 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.

Face to face mounting

Parallel mounting

• Never use this product as a sensing device for

personnel protection.

• In case of using sensing devices for personnel

protection, use products which meet laws and

standards, such as OSHA, ANSI or IEC etc.,

for personnel protection applicable in each

region or country.
