Notes: 1) The model No. with suffix '-J' stands for the connector type. (EQ-34W is excluded.)
(e.g.) As for the connector type of EQ-34: 'EQ-34-J'
Use the mating cables as shown below.
CN-24-C2 (Straight type, 4-core, 2m)
CN-24-C5 (Straight type, 4-core, 5m)
The model No. with suffix '-C5' stands for the 5m cable length type. (EQ-34-PN is excluded.)
(e.g.) As for the 5m cable length type of EQ-34 'EQ-34-C5'
2) The adjustable range stands for the maximum sensing range which can
be set with the adjuster. The sensor can detect an object 0.1m, or more,
away. However, the detectable area of the Near (Sub) type of the
EQ-34W begins at 0.2m.

3 CAUTIONS
●
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 switch-
ing regulator, ensure that the frame ground
(F.G.) terminal of the power supply is connect-
ed to an actual ground.
●
In case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicini-
ty 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 race-
way. This can cause malfunction due to induction.
●
Extension up to total 100m, is possible with
2
0.3mm , or more, cable. However, in order to re-
duce 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 pla-
ces 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 con-
tact 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 con-
nector type sensor, the tightening torque should
be 0.4N･m or less.
4 MOUNTING
● The tightening torque should be 0.8N･m or
less.

● Care must be taken regarding the sensor
mounting direction with respect to the object's
direction of movement.

●
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 up-
wards to avoid wrong operation.
