Thank you very much for purchasing Panasonic products. Read this Instruction 

Manual carefully and thoroughly for the correct and optimum use of this product.

Kindly keep this manual in a convenient place for quick reference.


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.

Although this product corresponds to a Class 1 laser product, it is 

dangerous to see the laser beam which has been passed through a 

viewing optical system such as a lens etc. Hence, please avoid this.

Use of control or adjustment or performance of procedures other 

than those specified in this instruction  manual  may result in 

hazardous radiation expose.

This product has been designed to meet the specifications when it is used 

along with the optional exclusive amplifier. If an amplifier other than the 

exclusive amplifier is used, not only the specifications may not be met, but it 

may also be a cause for malfunction or break down. Hence, please ensure to 

use this product along with the optional exclusive amplifier.








This product has been developed / produced for industrial use only.

Always use the sensor with the connector to be joined to the amplifier.

Make sure that the power is off while wiring to the amplifier.

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.

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.

Do not use the sensor during the initial transient time (0.5 sec.) just after the 

power supply is switched on.

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.

Take care that the sensor head is not directly exposed to fluorescent lamp 

from a rapid-starter lamp or a high frequency lighting device, as it may affect 

the sensing performance.

The sensor head cable cannot be extended.

Make sure that stress is not applied directly to the sensor head cable joint.

This sensor is suitable for indoor use only.

Do not allow any water, oil fingerprints, etc., which may refract light, or dust, 

dirt, etc., which may block light, to stick to the emitting / receiving surfaces of 

the sensor head. In case they are present, wipe them with a clean, soft cloth 

or lens paper.

Do not use the sensor in vaporous, dusty or corrosive gas atmospheres.

Take care that the sensor does not come in contact with water, oil, grease or 

organic solvents, such as, thinner, etc.

Make sure that the power is off while cleaning the emitting / receiving 

windows of the sensor head.
