CAUTIONS ON HANDLING LASER LIGHT
●
For the purpose of preventing any injury which may occur to the user by the use
of the laser product in advance, the following standards have been established by
the IEC Standards, JIS Standards, GB Standards and FDA Standards.
IEC : IEC 60825-1
-2007
JIS : JIS C 6802
-2011
GB : GB 7247.1
-2012
FDA : PART 1040.10
These standards classifies laser products according to the level of hazard and
provide the safety measures for respective classes.

●
Install the product so the laser beam comes higher or lower than eye level in order
not to watch the beam directly during operation. Laser safety distance (Nominal
Ocular Hazard Distance: NOHD) is approx. 1.4m. The laser beam must be termi
-
nated at the end of its path by a diffuse reflector or an absorber.
●
Please contact our company if the system breaks down. It is not equipped with a
function that stops laser radiation automatically during disassembling the sensor
head. The users therefore may be exposed to laser beam in disassembling the
sensor head.
● When this product is used in China, affix the Chinese warning label (accessory)
on the label in the product.
●
Do not use the system in the manner other than specified in this Instruction Manual.

Notes: 1) Measuring conditions are as follows unless otherwise specified; connection with controller, power voltage:
24V DC, ambient temperature: 20°C, sampling cycle: 40μs, average times:256, at measurement center dis

tance, object substance: white ceramic,, and digital measurement value.
2) Use the external ND filter (optional) in case the amount of reflected beam is too large on Specular Reflection
installation.
3) The measurement range is limites between -70 and +200mm (in case the sampling cycle is 20μs), or be
-
tween +100 and +200mm (in case the sampling cycle is 10μs).
4) This is based on the FDA Standard, according to Laser Notice No. 50 of the FDA Standard.
5) The figure shows the value at measurement center distance. It is determined by 1/e
2
(approximately 13.5%)
of center beam intensity. Due to leak light outside the specified area, the reflectance around the detecting
point may be higher than at the point and this may affect the measurement value.
6) The variation in ambient illuminance is ±0.08%F.S. or less.
