BASIC PERFORMANCE
High accuracy measurement
A red semiconductor
laser is used as the
emitting device and CCD
is used as the receiving
device. An ideally
parallel optical beam is
emitted enabling high
accuracy measurement.
Safety countermeasures not required
Red semiconductor
laser
CCD
Safety counter measures, such as protective gear, etc.,
are not required since LD-600 uses a Class 1 laser as
per IEC standards, and LD-601 uses a Class II laser as
per FDA regulations.

Refer to p.1595 for general precautions and p.1593~ for information about laser beam.
• This catalog is a guide to select a suitable product. Be
sure to read instruction manual attached to the product
prior to its use.
• 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.

warming up time of 3 min. approx. after the
power supply is switched on.
• Never disassemble the sensor head.
Safety standards for laser beam products
• A laser beam can harm human being’s eyes, skin, etc.,
because of its high energy density. IEC has classified
laser products according to the degree of hazard and the
stipulated safety requirements.
The LD series is classified as Class 1 laser.
• The LD series is CE compliant and complies with EMC
directives. EN 61000-6-2 is the applicable standard
that covers immunities relating to use of this product,

PRECAUTIONS FOR PROPER USE
Refer to p.1595 for general precautions and p.1593~ for information about laser beam.
Wiring
• Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• Make sure to use an isolation transformer for the power
supply. It an auto-transformer (single winding transformer) is
used, this product or the power supply may get damaged.
• In this sensor head, capacitor earth is used to enhance
the noise characteristics. In case there is a high frequency
noise generating equipment, such as, an ultrasonic welding
machine, etc., near the sensor head and if the mounting base
is electrically conducting (metallic, etc.), then insulate the
sensor head from the mounting base.
• In case noise generating equipment (switching regulator,
inverter motor, etc.) is used in the vicinity of the sensor head
or the controller, connect the frame ground (F.G.) terminal of
the equipment to an actual ground.
• In case a surge is generated in the used power supply,
connect a surge absorber to the supply and absorb the surge.
• 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.
• In order to reduce noise, make the wiring as short as possible.
Others
• This product is not a measuring instrument. Hence, the
company does not offer any calibration services.
• 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.
• Avoid dust, dirt, and steam.
• Take care that the sensor head and the controller does not
come in direct contact with water, oil, grease, or organic
solvents, such as, thinner, etc.
• Take care that the sensor head and the controller are not
directly exposed to fluorescent light from a rapid-starter
lamp or a high frequency lighting device, as it may affect the
sensing performance.
