This product has been developed / produced for
industrial use only.
Make sure that the power supply is OFF while wiring.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within
the rating.
If power is supplied from a commercial switch­ing regulator, ensure that the frame ground
(F.G.) terminal of the power supply is connect­ed to an actual ground.
In case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicini­ty of this product, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
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.
Extension up to total 100m, is possible with

0.3mm2, or more, cable. However, in order to re­duce noise, make the wiring as short as possible.
Do not use during the initial transient time
(50ms) after the power supply is switched on.
Take care that the sensor is not directly exposed
to fluorescent lamp from a rapid-starter lamp, a
high frequency lighting device or sunlight etc., as
it may affect the sensing performance.
Avoid dust, dirt, and steam. Do not use it in pla­ces having excessive vapor, dust, etc., or where
it may come in direct contact with corrosive gas.
Take care that the sensor does not come in con­tact with water, oil, grease, organic solvents, such
as, thinner etc., strong acid or alkaline.
This sensor is suitable for indoor use only.
Make sure that stress by forcible bend or pulling
is not applied directly to the sensor cable joint.
Since the cable end is not waterproof, do not
use the sensor in the application where water
may seep in from the cable end.
When connecting the mating cable to the con­nector type sensor, the tightening torque should
be 0.4N･m or less.

Detection may become unstable depending on the setting conditions or the sensing objects. After setting up this product, make
sure to check operations using actual sensing objects.

● Care must be taken regarding the sensor

mounting direction with respect to the object's
direction of movement.

Do not make the sen­sor detect an object

●●When detecting a specular object (aluminum or

copper foil, etc.) or an object having a glossy
surface or coating, please take care that there
are cases when the object may not be detected
due to a small change in angle, wrinkles on the
object surface, etc.
When a specular body is present below the
sensor, use the sensor by tiling it slightly up­wards to avoid wrong operation.

●●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.

WARNING

●

The models listed under ' SPECIFICATIONS'

●●If a specular body is present in the background,

wrong operation may be caused due to a small
change in the angle of the background body. In
that case, install the sensor at an inclination
and confirm the operation with the actual sens­ing object.
Some object may produce the dead zone right
in front of the sensor.

●

Since the EQ-30 series uses a 2-segment pho­todiode as its receiving element, and sensing is
done based on the difference in the incident
beam angle of the reflected beam from the
sensing object, the output and the operation in­dicator operate according to the object distance.
Further, the stability indicator shows the margin
of the incident light intensity and not that of the
object distance.
Hence, the distance at which it lights up / OFF
depends on the object reflectivity and is not at
all related to the output operation. Do not use
the sensor when the stability indicator is OFF
(unstable light received condition), since the
sensing will be unstable.

EQ-34, EQ-34-PN

● Adjusting procedure

Note: Use the accessory adjuster screwdriver to turn the distance

adjuster slowly. Turning with excessive force will cause dam­age the adjuster.

①

④

Turn the distance adjuster fully counter­clockwise to the minimum sensing range
position of 0.2m approx.

Place an object at the required distance
from the sensor, turn the distance adjuster
gradually clockwise, and find out point
where the sensor changes to the light re­ceived condition.

Remove the object, turn the distance ad­juster further counterclockwise, and find
out point where the sensor changes to
the light received condition again with only
the background.

When the sensor does not go to the light
received condition even if the adjuster is
fully turned clockwise, point is this ex­treme point in the range.

The optimum position to stably detect ob­jects is the center point between and .

The following distance adjusting procedure for
EQ-34, EQ-34-PN and the Far (Main) side / Near
(Sub) side of EQ-34W is for use when a sensing
object moves horizontally to the sensor. When a
sensing object is approaching / moving away
from the sensor, follow only steps ① and ② re­spectively.
Since the sensing point may change depending
on the sensing object, be sure to check the oper­ation with the actual sensing object.
