Safety precaution
WARNING
●
Never use this product as a sensing device for personnel protection.
●
In case of using 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.
●
This product has been developed / produced for industrial use only.
●
The narrow beam type
EX-1
□
S
□ emits a narrow light beam, so it is difficult to align the beam. Use
the instrument with the emitter and the receiver facing each other in a straight line. Note that if
screws or other parts become loose due to vibration, for example, the beam axis may drift.
●
Sensor mounting baracket (optional)
MS-EX-10-
□
is an object for satandard-beam type.
It cannot be used for narrow-beam type.
● For the convergent reflective type
EX-14
□, if there is a reflective object (e.g., a conveyor, etc.) in
the background of the sensing object, since it may affect the sensing, use by keeping enough dis-
tance from the reflective object.
●
The thin cable 0.1mm2 is used for this product. Thus, take care that if the cable is pulled with ex-
cessive force, it may cause cable break.
●
Extension up to total 50m (each emitter and receiver of thru-beam type), or less, is possible with
0.3mm2, or more of conductor area cable. However,the extension of a power supply line and the
output line of less than 10m is acceptable in case using this product as conforming to S-mark.
●
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 race-
way.
● 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.
●
Do not use during the initial transient time (
EX-15
□,
EX-15E
□,
EX-17
□,
EX-17E
□: 100ms / others:
50ms) after the power supply is switched ON.
●
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 con-
tact with corrosive gas, etc.
●
Take care that the product does not come in contact with oil, grease, organic solvents such as
thinner, etc., strong acid or alkaline.
● This product cannot be used in an environment containing inflammable or explosive gasses.
●
Never disassemble or modify the product.
●
Since the cable end is not waterproof, do not use the sensor in the application where water may
seep in from the cable end.
