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.
This product is not easily affected by the reflected light in-
tensity since this sensor is the adjustable range reflective
type. When the reflected light intensity is remarkably low, the
sensing range may be affected. In that case, mount the sen-
sor, while checking light-up of the stable indicator (green).
Mounting screws of the terminal cover and display cov-
er should certainly be tightened to maintain the water
tight rating, however, the tightening torque of the
screws should be of 0.3 to 0.5N㨯m.

When detecting a specular object (aluminum or copper
foil, etc.) or an object having a glossy surface or coat-
ing, 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.

Make sure that the power supply is off while wiring and adjusting.
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 reg-
ulator, ensure that the frame ground (F.G.) terminal of
the power supply is connected 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.
In case noise generating equipment (switching regula-
tor, 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.
Take care that the sensor is not directly exposed to fluo-
rescent light from a rapid-starter lamp or a high frequency
lighting device, as it may affect the sensing performance.
If an external surge voltage exceeding 4kV (DC-voltage:
1kV) is impressed, the internal circuit will be damaged,
and a surge suppressing element should be used.
Do not use during the initial transient time (50ms) after
the power supply is switched on.
This sensor is suitable for indoor use only.
A mechanical structure is employed for the distance ad-
juster of this product. Take care not to drop the product.
Do not use this sensor in places having excessive va-
por, dust, etc., or where it may come in direct contact
with water, or corrosive gas.
Take care that the sensor does not come in direct con-
tact with water, oil, grease, or organic solvents, such
as, thinner, etc.
This sensor cannot be used in an environment con-
taining inflammable or explosive gases.
Never disassemble or modify the sensor.

Check all wiring before applying power since incorrect
wiring may damage the internal circuit.
Also, carefully tighten the terminal screws so that the
wires of adjacent terminals do not touch.
The mounting hole for screw the terminal cover fixing
inclines 70 degrees to the
terminal cover, as shown
in the figure below.
To avoid damaging this
product or a screw, take
care when tightening or
loosening a screw.

To maintain a watertight performance, the cable should
have an outer diameter between Ǿ9 to Ǿ11mm with a
smooth covering material that allows the accessory con-
duit connector to be securely tightened, however, the tight-
ening torque of the screw should be of 1.5 to 2.0N㨯m.

Detection-ON mode is obtained when the
switch is turned fully clockwise.
Detection-OFF mode is obtained when the
switch is turned fully counterclockwise.

٨Since the EQ-500 series use a 2-segment photo-
diode 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 (orange) operate
according to the object distance.
Further, the stability indicator (green) shows the
margin to the setting distance.

An OFF-delay timer, which is useful when the re-
sponse of the connected device is slow, etc., an
ON-delay timer, which is useful when the input
specifications of the connected device require a sig-
nal of a fixed width, are possible with EQ-5غT.
The OFF-delay timer and the ON-delay timer can be
used at the same time.
For DC-voltage type, set the DIP switch for the timer
