5SENSITIVITY ADJUSTMENT

Step

Turn the sensitivity adjuster fully counterclockwise

to the minimum sensitivity position, MIN.

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.

In the dark condition, turn the sensitivity adjuster further

clockwise until the sensor enters the “Light” state op-

eration and then bring it back to conrm point B where

the sensor just returns to the “Dark” state operation.

If the sensor does not enter the “Light” state

operation even when the sensitivity adjuster is

turned fully clockwise, the position is point B.

4. The position at the middle of points A and B

is the optimum sensing position.

6CAUTIONS

●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.

●EX-24□ are not incorporated with a sensitivity adjuster.

If there is a reflective object (conveyor, etc.) in the back-

ground, since it may affect the sensing, use these models

by keeping enough distance from the reective object.

● If a reective object is present in the background, the sensing

of EX-28□ may be affected. When setting the sensor, make

sure to conrm that the reective object has no effect. In case

the reective object affects the sensing, take measures such

as removing the reective object or coloring it in black, etc.

●If sensors are mounted close together and the ambient temperature is near

the maximum rated value, provide for enough heat radiation / ventilation.

●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.

●Extension up to total 50m (each emitter and receiver

of thru-beam type), or less, is possible with 0.3mm

2, or

more of conductor area cable. However , the extension of

a power supply line and the output line less than 10m of

is acceptable in case using this product as conforming to

S-mark

●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 de-

vice 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.

7RoHS DIRECTIVE

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

●Chinese RoHS indicates inclusion despite regulation

value. (Refer to Chinese part.)
