Installation and adjustment
Always read these precautions carefully before use.
WARNING WARNING
1. Check for internal voltage drop of sensor switches.
When reed sensor switches with indicator lamps or 2-lead
wire solid state sensor switches are connected in series
causes increasing internal voltage drop, and the load may fail
to activate. Connecting n-pieces will drop the internal voltage
by n times as large.
Ensure the circuit satisfy the following inequality.
Power supply voltage — Internal voltage drop×n > Minimum
operating voltage of the load
In relays with rated voltage of less than 24VDC, check to see
the above inequality is satisfied even when n＝1.
When the above inequality is not satisfied, select a reed sen-
sor switch without indicator lamp.
2.Do not use Koganei sensor switches with other com-
pany's cylinders.
The sensor switches are designed for use with our Koganei
cylinders only. Using with other company's cylinders may not
function properly.
1.Check the specifications.
Using outside of specification range in voltage, current, temper-
ature, shock, etc. creates the risk of breakdown or malfunctions
of the product. Read the specification carefully before using.
2. Avoid mounting cylinders in close proximity to each othe r
When more than two cylinders with sensor switches are used
close to each other, see page E. This can cause the sensor
switch to malfunction due to the magnetic interference with
each other.
3. Where the position detection is made at mid-stroke,
be cautious against the sensor switch ON time.
Be aware that, when the sensor switch is mounted at interme-
diate point of cylinder stroke to detect passing of the piston,
too fast speed of the piston can shorten the sensor switch
operation time, causing the load, such as programmable con-
trollers, to fail to operate.
The highest detectable cylinder speed is
4. Keep wiring as short as possible.
The wiring for solid state sensor switches must be 30 m
[98.4ft] or shorter, as stipulated by EN standard. For reed sen-
sor switches, the longer wiring (10 m [32.8 ft] or longer) will
lead to the larger capacitive surge current, which reduces the
operating life of sensor switches. When a longer wiring cannot
be avoided, provide the protective circuit described in the cat-
alog.
If the load is inductive or capacitive, provide the appropriate
protective circuit as described in the catalog.
5.Avoid repeated bending or excessive pulling of lead
wires.
Applying repeated bending or pulling force on the lead wires
could cause breaking the wire.
6.Check for leakage current.
2-lead wire solid state sensor switches produce the current
(leakage current) even at off condition to activate the internal
circuit. Ensure that they satisfy the following inequality:
Input off current of programmable controller > Leakage current
If above inequality is not satisfied, select 3-lead wire solid
state sensor switch. And, if n-pieces sensors are connected in
parallel, the leakage current increases by n times.
1. Do not apply an external magnetic field to the sensor
switch while the cylinder is in operation.
This may cause unintended operation, thereby damaging the
device and causing personal injury.

Design and Selection
CAUTION
1.Ensure a safe installation environment for the cylin-
ders with sensors.
The sensor switch should not be used in a location where
large current or high magnetic field is present. It could result
in erratic operation.
Do not use magnetic material for the mounting portion. This
may cause erratic operation.
2.Install the sensor switches in the center of their
operating range.
Adjust the mounting position of the sensor switch so that the
piston can stop in the center of the operating range (the sen-
sor turned-on range). Setting the switch ON the end of the
operating range (at the boundary of ON/OFF) may cause the
operation to be unstable. Also be aware that the operating
range will vary according to the temperature change.
3.Follow the tightening torque for the sensor switches
when mounting.
Tightening the screw exceeding the allowable tightening
torque may damage the mounting thread, mounting bracket,
sensor switch etc. In addition insufficient tightening torque
could cause the sensor switch position to be changed, there-
by resulting in unstable operation. For details about tightening
torque, refer to Page E.
4.Do not carry the cylinder by its mounted sensor
switch's lead wire.
After mounting a sensor switch on the cylinder, do not carry
the cylinder by grabbing the lead wire. This may not only dam-
age the lead wire but also apply stress to the inside of the
sensor switch that may damage internal elements, so never
perform such behavior.
5.Do not drop the sensor switches or bump them
against other objects.
When handling the product, take care to avoid dropping it,
allowing it to bump against other objects, or otherwise sub-
jecting it to excessive impact (294.2 m/s [30G] or more).
In the case of reed sensor switches, such behavior may
cause the contact to malfunction, thereby giving a signal
instantaneously or turning off the signal. And, this may
change the contact interval, thereby deteriorating the sensor
switch's sensitivity. As such, this may cause the device to mal-
function. Even if the sensor switch case is not damaged, the
inside of the sensor switch may be damaged, causing erratic
operation.
CAUTION
Safety Precautions (Sensor switch)

6
1.Prevent nearby moving objects from coming into
contact with sensor switches.
When the cylinders equipped with sensor switches are mov-
ing, or when moving objects are nearby, do not let them come
into contact each other. In particular, lead wires may become
worn or damaged causing unstable operation of the sensor
switch. In the worst case , this may result in current leakage or
electric shock.
2.Always turn off the power before performing wiring
work.
Wiring work while the power is on could result in electric
shock. Also, incorrect wiring could damage the sensor switch
in an instant. Turn on the power after completing the wiring
work.
1.Check the "catalog" and other reference materials
for correct wiring.
Improper wiring could result in abnormal operation.
2.Do not share wiring with power or high voltage lines.
Avoid wiring in parallel to or shared in the same conduit with
power line and high-voltage line. Such wiring could cause the
sensor switch and control circuit to suffer erratic operation by
electric noise.
3.Be cautious against not bending the lead wire
repeatedly or applying tension force to the wire.
Applying repeated bending stress or tension force to the lead
wire may cause the wire to be broken.
4.Check polarity in the wiring.
For the sensor switch with the polarities (＋, −, output) indicat-
ed, make sure that wiring connections are correct. The wrong
polarities will result in damage to sensor switches.
Wiring
DANGER
WARNING
Safety Precautions (Sensor switch)
1. Avoid short circuiting loads.
Turning on the sensor switch while the load is short-circuited
causes overcurrent, which will damage the sensor switch in
an instant.
Example of short-circuit load: Sensor switch’s output lead wire
is directly connected to the power supply.
CAUTION
Always read these precautions carefully before use.

Handling Instructions and Precautions
In single acting type, when applying air from the piping port of
the cylinder and leaving the cylinder for long hours with the
spring compressed, the piston may not be returned even if the
air is exhausted. In such cases, use double acting type cylinders.
Cylinder with magnet (the sensor cylinder) has a built-in magnet
for sensor switch. Mounting the sensor switch enables the
detection of piston position.
1. Before piping for the cylinder, always flush the piping
completely by blowing compressed air through it. Entering
machining chips, sealing tape, or rust produced during piping
work may cause operating failures including air leakage.
2. When screwing a piping or fitting into the cylinder, be sure to
tighten them under appropriate tightening torque shown below.
Piping
The cylinder can be used without lubrication, but if lubrication is
required, use turbine oil Type 1 (ISO VG32) or equivalent. Do not
use spindle oil and machine oil.
Lubrication
1. When using the cylinder in a location subject to water droplet
and oil droplet or likely to be exposed to dust, protect the
cylinder with something to cover.
2. Do not use the cylinder in a corrosive atmosphere. The use of
the cylinder under such atmosphere may damage the cylinder
or cause its defective operation.
3. Do not use the cylinder under extremely dry condition.
4. The ambient temperature range most suitable for using the
cylinder is 5 to 60°C [41 to 140°F]. The temperature exceeding
60°C [140°F] may damage the cylinder or cause defective
operation, so be sure to avoid using the cylinder under such
conditions. And, the temperature 5°C [41°F] or below may
cause moisture in the air to be frozen, thereby damaging the
cylinder or causing defective operation. Take some anti-
freezing measure.
Atmosphere
When used
Others
Sensor switch
1. Use air as the media. For the use of any other media, consult
our nearest sales office.
2. For air used in the cylinder, be sure to use clean air which
does not contain degraded compressor oil, etc. Install an air
filter (filtration of 40µm or less) near the cylinder or valve to
remove sedimentation and dust. Also drain the air filter
periodically. Entering of impurities and dust into the cylinder
may cause its operating failure.
Air supply
General precautions
NoteNote 1. For mounting position and moving procedure of the
sensor switch, refer to E Page F.
2. When an inductive load will be connected to reed sensor
switches or if capacitive surge will occur, take some
contact protection countermeasures. For contact
protection countermeasures, refer to Page C.
1. Do not place your hands in the cylinder operating direction.
2.
In the initial operation, be cautious against cylinder operating direction.
3. When the cylinder is retracting, be cautious against part of your body
not be caught in a gap between the cylinder body and the end plate.
4. At the time of maintenance, be sure to check that there is no
residual pressure within the cylinder before performing the work.
5. The cylinder speed should be 500 mm/s or less when using
the cylinder. However, even within the allowable range, if the
speed and load are large, install an external stopper to avoid
applying direct impact to the cylinder.

Handling Instructions and Precautions
Mounting
1. Any mounting posture is available but the mounting surface
should be flat surface. Occurrence of twist or bending when in
installation could not only deteriorate the accuracy but also
cause air leakage or defective operations.
2. Take caution that scratched or dented mounting surface of the
cylinder may deteriorate the flatness.
3. When the impact is too large, be sure to install some support
bracket on the cylinder in addition to mounting screws.
4. Ensure to keep enough strength for the cylinder and
mounting screws.
5. When the screws may be loosened by the impact or vibration,
take measures against screw loosening.
6. The sliding portion of the piston rod should not be scratched
or dented. Scratched or dented sliding portion could damage
seals and cause air leakage.
7. Do not wipe out the grease applied on the piston rod and
linear guide. This may cause the product to defective
operation. If oil cannot be found, apply grease to them.
(Grease: Universal type Lithium based grease No. 2)
8. To tighten the cylinder, use the following tightening torque.
When using female threads of the main body for mounting,
tighten the screw under the tightening torque shown in ( ).
Mounting
Avoid the following usages.
9. When thrust of a cylinder with guide directly apply to the plate,
apply the force to the rod axis center.

10. Mounting of workpiece
For the cylinder with guide, a workpiece can be mounted on
two surfaces.
To tighten screws for mounting a workpiece, tighten at a
torque within its limited range.
1. As the plate table is supported by the linear guide, do not
apply strong impact or excessive moment to it when
mounting a workpiece.
2. When securing a workpiece in a plate table with screws,
hold the table to tighten screws. Tightening with the body
held may apply excessive moment to the guide portion,
causing deteriorating the accuracy.
