mable or explosive gases.

1Overview
This product is a compact laser displacement sensor, incorporating a digital
display and controller functions.
●The standard type has three digital outputs and 1 analog output for
current or voltage.
●The multifunction type additionally incorporates serial communication
functions and can be easily controlled by host devices.
●One out of four measurement distances can be selected for each type
that support both NPN and PNP outputs.
2Cautions for Handling Laser Light
In order to prevent accidents caused by laser products and to protect the
users, IEC, JIS and FDA established the following standards: These stan-
dards classify laser products according to their level of hazard and provide
safety measures for the respective classes.
●IEC: IEC 60825-1-2007 (EN 60825-1-2007)
●JIS: JIS C 6802-2005
●FDA: PART 1040 (PERFORMANCE STANDARDS FOR LIGHT-EMIT-
TING PRODUCTS)
Laser hazard class
Classication according to IEC 60825-1-2007 (JIS C 6802-2005)
Class Model Description of hazardous evaluation
Class 2 HL-G1qq-A-C5
HL-G1qq-S-J
Visible beam, low power. Blink response of
eye affords protection.
Warning label and label position
Installation and operation
●Install the product so that the laser beam is above or below eye level.
●Do not look into the beam directly during operation. A safe distance
from the laser (Nominal Ocular Hazard Distance: NOHD) is approx.
0.4m.
●The laser beam must be terminated at the end of its path by a diffuse
reector or an absorber.
●Please contact Panasonic Electric Works SUNX Co., Ltd. if the system
breaks down. It is not equipped with a function that stops laser radia-
tion automatically when the sensor head is being disassembled.
● Do not use the system in any other manner than specied in this
instruction manual.
3Wiring instructions
WARNING
Turn OFF the power supply before connecting or disconnecting the con-
nectors or performing wiring.
Connections
●When connecting or disconnecting the connectors, hold the connector
area so that no extra force is applied to the cable.
●Do not touch the terminals or to let foreign objects get into the connec-
tors after disconnecting them.
●Do not apply force around the connector of the sensor head cable
or the extension cable. Do not bend the cables near the connectors
because the cables will be disconnected.
●When moving the sensor head during operation, install the cables in
such a way that they do not bend while the sensor head is moving.
Use the multifunction type if bending the cables is inevitable as there
are replaceable extension cables available for this type.
Wiring
●Do not roll up the sensor cable (bundle in parallel) with other wiring.
Keep it at least 100mm away from other wires.
Cables should be separated from high voltage and power circuit lines.
If this is not possible, shield the cable by running it through conductive
material such as grounded electrical conduit.
●Install the product as far away as possible from noise sources such as
high-voltage lines, high-voltage devices, power lines, power device,
machines which generate a large high-voltage ON/OFF surge, welding
machines and inverter motors.
●Do not pull the cable with a force more than 29.4N when wiring the
cable when the sensor head is xed. The cable may be bent with a
radius of 30mm or more. However, do not bend the cable within 20mm
of the sensor head.
20mm min.
R 30mm min.

2
●Make sure that the length of signal and power lines connected to the
product is less than 30m in order to meet the CE marking require-
ments.
●Attach a ferrite core to the head cable as shown.
30mm max.
Warming Up
●Allow the product to warm up for at least 30 minutes after turning on
the power to ensure good performance.
Environment
●Mount the sensor head on an aluminum or steel plate with a minimum
surface area of 200cm2if the ambient temperature is 40°C or higher.
When installing two or more sensor heads in parallel, mount each
sensor head on an aluminum or steel plate with a minimum surface
area of 200cm2and make sure that the ambient temperature does not
exceed 40°C.
●The life of the semiconductor laser depends on the ambient tempera-
ture during use. When using the product near a heat source, take
measures to keep the ambient temperature of the sensor head as low
as possible.
Mount the sensor on a device that allows heat to dissipate because
the sensor itself also generates heat.
●Keep the emitter surface and the receiver surface clean. Prevent light
refractors such as water, oil and ngerprints, and light blockers such
as dust and dirt from contaminating the surface. When cleaning these
parts, wipe them off using a soft lint-free cloth or lens cleaning paper.
●Install the sensor head at a location where external light (such as
sunlight or light which has the same wavelength as the laser beam) do
not enter the receiver. If high accuracy is required, install a light shield
plate or something similar around the sensor head.
●Do not use the product underwater or in the rain. Although the sensor
head has an IP67 degree of protection, the connectors are not dust-
proof, waterproof, or corrosion-resistant.
●Do not use the product in dusty places or in places that are exposed to
ammable or corrosive gases, droplets, direct sunlight, severe vibra-
tion or impacts.
