● Use shielded cables for analog output and make the line as short as possible because it is
particularly liable to be affected by an external noise.
● Install the product as much as possible away from high-voltage lines, high-voltage devices,
power lines, power devices, devices with large switching surges, welders, inverter motors
and other noise generation sources.
● Do not apply stress such as excessive bending or pulling to the extracted part of a cable.
Operating environment
● This product is suitable for indoor use only.
● Do not install the sensor in the following locations.
• Locations subject to flammable gas, corrosive gas, or excessive dust
• Locations subject to water drops
• Locations subject to dust, metal particles, or saline matter
• Atmospheres containing benzine, paint thinner, alcohol, or other organic solvents or
strong alkaline substances such as ammonia or caustic soda
• Locations subject to severe vibration or shock
• Locations subject to direct sunlight
• Locations subject to water, oil, or chemicals
• Locations where load is applied to the sensor
● Use the product in an environment where the temperature ranges between -10
℃
and +45
℃
. Also, store the product in an environment where the temperature ranges between -20
℃
and +60
℃
. However, avoid using the product in an environment where icing may occur.
● Use the product in an environment where the humidity ranges between 35% RH and 85%
RH. Also, store the product in an environment where the humidity ranges between 35% RH
and 85% RH. However, avoid using or storing the product in an environment where dew
condensation may occur due to a sudden temperature change.
● Use the product with illuminance of 3,000 lx or less on the light receiving surface of an
incandescent lamp.
● Do not use the product in a location where the ambient temperature, ambient humidity, and
illuminance on the light receiving surface exceed the operating environment ranges.
● Avoid using this product in environments where condensation occurs due to sudden
temperature change.
● The service life of a semiconductor laser depends on the ambient operating temperature.
When using the product near a heat generation part, lower the ambient temperature as
much as possible by cooling, etc.
● Since the sensor itself generates heat, install the sensor on a material with good heat
radiation.
● Performance may not be satisfactory in a strong electromagnetic field.
● Do not allow extraneous light such as sunlight or other light that has the same wavelength
as the laser to directly hit the beam receiving part. In particular, if precision is required, use
this product by mounting a douser or similar material.
● Keep the light emitting and receiving windows of this product clean and free of water, oil,
fingerprints, and other substances that refract light as well as dust, grit, and other objects
that intercept light. When cleaning the surfaces, wipe them with a lint-free soft cloth or lens
cleaning paper.
● Make sure to turn OFF the power supply before cleaning the light emitting and receiving
windows of this product.
● This product is a precision device. Do not drop or otherwise subject to shock. Doing so may
cause product failure.
