DESCRIPTION

 

 

HL-C235BE

HL-C235BE

-

MK

 displacement sensor head achieves ultra high-

speed and high-accurate measurement using linear image sensor as light receiv-

ing element to be used on equipment that require high-speed operation with high-

accuracy.

 

●  The product is used at diffuse or specular reflection sensor head by installing and 

setting.

CAUTIONS ON HANDLING LASER LIGHT

 

 In order to prevent the accident by laser product and protect the users, JIS C 

6802

-2014

 “Safety of laser products” was established based on the regulation of 

IEC (International electrotechnical Commission). This regulation classifies laser 

products according to the level of hazard, and provides the safety measures for 

respective classes.

HL-C235BE

HL-C235BE

MK

 are classified as “Class 2 laser products” according 

to IEC 60825-1

-2014

 (JIS C 6802

-2014

) “Safety of laser products”.

Description of hazardous evaluation

Class 2

HL-C235BE

HL-C235BE-MK

Visible beam, low power. Blink response of eye affords protection.

 

 WARNING  label

In Chinese

In Japanese / English / Korean

<Label position>

 

 Install the product so the laser beam comes higher or lower than eye level in or-

der 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 terminated 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.

EXPORT REGULATIONS BY JAPANESE GOVERNMENT

 

 Please follow the export control regulations required.

HL-C235BE 

and 

HL-C235BE-MK

 are not subject to export control regulations 

under the condition that they are used combined with the non-pertinent controller 

to export control specified by Foreign Exchange and Foreign Trade Law.

When they are combined with the pertinent controller to export control, they are 

subject to the Law. In this case export admission by Japanese government is re-

quired before the product is to be exported or brought out of the country.

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 0 and +50mm (in case the sampling cycle is 20μs at diffuse re

-

flection), between 0 and +42mm (in case the sampling cycle is 20μs at specular reflection), b36 and 

+50mm (in case the sampling cycle is 10μs at diffuse reflection), or b36 and +42mm (in case the 

sampling cycle is 10μs at specular reflection).

 

4) The figure shows the value at measurement center distance. It is determined by 1/e

 (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.

 

5) The variation in ambient illuminance is ±0.03%F.S. or less.

 

6) It does not work properly in case connected to the controller ver. 1.**.
