Cautions on Handling Laser Light
JIS/IEC/GB/KS
■ Semiconductor laser is used as the light source of sensor
The laser is classified based on JIS (JIS C 6802:2014) and IEC (IEC
60825-1:2014), GB (GB 7247.1:2012), KS (KS C IEC 60825-1:2013)
standards.

■ Cautions
1) Be careful not to directly watch the laser beam or its reflected light from a
mirror surface.
2) Install the sensor 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.
0.4m for HL-C203B
□
(-MK) and HL-C205
□
(-MK), is approx. 0.5m for
HL-C208
□
(-MK) and HL-C211
□
(-MK), is approx. 1.4m for
HL-C235BE(-MK) / HL-C235CE(-MK), HL-C235CE-W(MK). The laser beam
must be terminated at the end of its path by a diffuse reflector or an absorber.
3) Laser beam emission can be stopped by using the laser control input
terminal. (
“2-1 Functions and Arrangement of I/O Terminal Block”
)
* Use the interlock control input terminal when using as an emergency stop
circuit for safety. Release the short circuit by short bar to stop laser emission.
4) Please contact Panasonic Industrial Devices SUNX if the system breaks
down. Laser radiation is not automatically stopped during disassembling
the sensor head. The users therefore may be exposed to laser beam in
disassembling the sensor head.
5) Do not use the system in the manner other than specified in this USER’S
MANUAL.
You may be exposed to hazardous laser radiation if the device
is controlled or adjusted in procedures not specified in this
manual.
6) Read the descriptions of the warning label carefully before use.
The warning label is affixed to the side of the sensor head. The Japanese and
English warning labels are packed with the sensor. Use them as needed.
