MEUEN-EX30 V2.0
Thank you for purchasing products from Panasonic Electric Works SUNX
Co., Ltd. Please read this Instruction Manual carefully and thoroughly for
the correct and optimum use of this product. Kindly keep this manual in a
convenient place for quick reference.
 This product has been developed / produced for industrial use only.
 A thin 0.1mm
2
cable is used for this product. Do not use excessive force
when pulling on the cable: it may cause cable to break.
 You can extend the cable up to 50m max. with 0.3mm
2
or more cable for
both emitter and receiver (thru-beam types). However, in order to reduce
noise, make the wiring as short as possible.
 Do not apply stress directly to the sensor cable joint by forcibly bending
or pulling.
 Make sure that the power supply is off while wiring.
 Incorrect wiring will damage the sensor.
 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.
 Verify that the supply voltage including the ripple 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 use during the initial transient time (0.5s) after the power supply is
switched on.
 Make sure to use an isolation transformer for the DC power supply. If an
auto-transformer (single winding transformer) is used, this product or the
power supply may be damaged.
 If it is possible that the power supply used may generate a surge,
connect a surge absorber to the power supply.
 Ensure that the sensor is not directly exposed to the following light
sources as they may adversely effect sensing performance: fluorescent
light from a rapid-starter lamp, a high frequency lighting device, sunlight
etc.
 Avoid dust, dirt and steam.
 Take care that the sensor does not come in contact with oil, grease,
organic solvents such as thinner, etc., strong acid, or alkalines.
 If the sensor is operating where static electricity is present, use a
grounded metal mounting plate.
Sensitivity adjustment is available for EX-32 and EX-33.
When EX-32 is used, adjust the sensitivity as follows. When EX-33 is
used, set the sensitivity adjuster to the MAX. position. However, if the beam
penetrates a sensing object, adjust the sensitivity as follows.
Procedure
This procedure assumes that “Light-ON” is set for the operation mode. If
“Dark-ON” is the operation mode, the output will behave the other way
around.
 Use a standard screwdriver and turn the adjuster slowly. Using
excessive force will damage the adjuster.

adjuster
Description
1 Turn the sensitivity adjuster fully counterclock-
wise to the minimum sensitivity position.
2 In the “light received” condition, turn the sen-
sitivity adjuster slowly clockwise to find point
A where the sensor output turns ON.
