3 MOUNTING

● Mount the sensor on a mounting plate 3mm

or less thick and Use the enclosed nut and
toothed lock washer for mounting.

● When the nut is tightened, hold the the sensor

with hand or a spanner etc. and the tightening
torque should be 0.6N•m or less. (
1N•m or less) Do not tighten the sensor itself.

Stability indicator (Green) (Note 1)

Lights up under the stable light
condition or the stable dark condition

5 SENSITIVITY ADJUSTMENT

Step

1.

Turn the sensitivity adjuster fully counterclockwise
to the minimum sensitivity position, MIN.

2.

In the light received condition, turn the sensitivity
adjuster slowly clockwise and conrm the point A
where the sensor enters the “Light” state operation.

3.

In the dark condition, turn the sensitivity
adjuster further clockwise until the sensor en­ters the “Light” state operation and then bring
it back to conrm point B where the sensor
just returns to the “Dark” state operation.

4.

The position at the middle of points A and

B is the optimum sensing position.

6 CAUTIONS

● This product has been developed / produced for industrial use only.

● The thin cable 0.1mm2 is used for this product. Thus, take care that
if the cable is pulled with excessive force, it may cause cable break.

● Extension up to total 50m (emitter and receiver each for thru­beam type), or less, is possible with 0.3mm2, or more, cable.

● Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.

● Make sure to carry out wiring in the power supply OFF condition.

● 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.

● 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 uorescent
lamp from a rapid-starter lamp, a high frequency lighting de­vice or sunlight etc., as it may affect the sensing performance.

● This sensor is suitable for indoor use only.

● Do not use this sensor in places having excessive vapor, dust,
etc., or where it may come in contact with corrosive gas, etc.

● Take care that the sensor does not come in contact with oil, grease,
organic solvents such as thinner, etc., strong acid, or alkaline.

● This sensor cannot be used in an environment contain­ing inammable or explosive gases.

● Never disassemble or modify the sensor.

● In case of using the sensor at a place where static electricity is generated,
use a metal mounting plate. Also, ensure to ground the mounting plate.

7 RoHS DIRECTIVE

● This equipment complies with RoHS (EC and Chinese directive).

● Chinese RoHS indicates inclusion despite regulation value. (Refer Chinese part.)
