label of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe
ISO 4414

Note 1)

, JIS B 8370

Note 2)

and other safety practices.

1.

The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.

Since the products specified here are used in various operating conditions, their compatibility with the
specific pneumatic system must be based on specifications or after analysis and /or tests to meet your
specific requirements. The expected performance and safety assurance will be the responsibility of the
person who has determined the compatibility of the system. This person should continuously review the
suitability of all items specified, referring to the latest catalogue information with a view to giving due
consideration to any possibility of equipment failure when configuring a system.

2. Only trained personnel should operate pneumatically operated machinery and

equipment.

Compressed air can be dangerous if handled incorrectly. Assembly, handling or maintenance of
pneumatic systems should be performed by trained and experienced operators.

3. Do not service machinery/ equipment or attempt to remove components until

safety is confirmed.

1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of
safe locked-out control positions.

2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply
pressure for this equipment and exhaust all residual compressed air in the system.

3. Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston
rod, etc. (Bleed air into the system gradually to create back pressure.)

4. Contact SMC if the product is to be used in any of the following conditions:

1. Conditions and environments beyond the given specifications, or if product is used outdoors.

2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or
safety equipment.

3. An application which has the possibility of having negative effects on people, property, and therefore
requires special safety analysis.

Trimmer Auto Switch Precautions 1

Be sure to read before handling

1. Confirm the specifications.

Read the specifications carefully and use this product
appropriately. The product may be damaged or malfunction if
it is used outside the range of specifications of current load,
voltage, temperature or impact.

2. Take precautions when multiple cylinders
are used close together.

When multiple auto switch cylinders are used in close
proximity, magnetic field interference may cause the switches
to malfunction. Maintain a minimum cylinder separation of
40mm. (When the allowable separation is indicated for each
cylinder series, use the specified value.)

3. Keep the wiring as short as possible.

Use a wire 3m or shorter between the sensor and amplifier.
Although wire length of power supply/output cable should not
affect switch function, use a wire 100m or shorter.

4. Take precautions for the internal voltage
drop of the switch.

5. Pay attention to leakage current.

Although a varistor for surge protection is connected at the
output side of a trimmer auto switch, damage may still occur if
the surge is applied repeatedly. When a load, such as a relay,
solenoid, which generates surge is directly driven, use a type
of switch with a built-in surge absorbing element.

6. Cautions for use in an interlock circuit.

When an auto switch is used for an interlock signal requiring
high reliability, devise a double interlock system to avoid
trouble by providing a mechanical protection function, or by
also using another switch (sensor) together with the trimmer
auto switch. Also perform periodic maintenance and confirm
proper operation.

7. Ensure sufficient clearance for maintenance
activities.

When designing an application, be sure to allow sufficient
clearance for maintenance and inspections.

Design & Selection

Warning

1. Do not drop or bump.

Do not drop, bump or apply excessive impacts (980m/s2
more for sensor unit and 98m/s

2

or more for amplifier un
while handling.
Although the body of the switch may not be damaged, th
inside of the switch could be damaged and cause
malfunction.

2. Do not carry a cylinder by the auto switc
lead wires.

Never carry a cylinder by its lead wires. This may not on
break the lead wires, but it may cause internal elements of th
switch to be damaged by the stress.

3. Mount switches using the proper tightenin
torque.

When a switch is tightened beyond the range of tightenin
torque, the mounting screws, mounting bracket or switch ma
be damaged. On the other hand, tightening below the rang
of tightening torque may allow the switch to slip out
position.

Mounting & Adjustment

1. Avoid repeatedly bending or stretching lea
wires.

Broken lead wires will result from applying bending stress
stretching forces to the lead wires.

2. Be sure to connect the connector for senso
to the amplifier before power is applied.

3. Confirm proper insulation of wiring.

Be certain that there is no faulty wiring insulation (contact w
other circuits, ground fault, improper insulation betwee
terminals, etc.). Damage may occur due to excess curre
flow into a switch.

4. Do not wire with power lines or high voltag
lines.

Wire separately from power lines or high voltage line
avoiding parallel wiring or wiring in the same conduit w
these lines. Control circuits, including auto switches, m
malfunction due to noise from these other lines.

5. Do not allow short circuit of loads.

Output is automatically stopped when the protection circuit
working, as the output unit registers any excess current flo
if loads are short circuited. Should this occur, shut off t
power supply, remove the cause of this excess current flo
and switch on the power again. Take special care to avo
reverse wiring between the power supply line (brown) and t
output line (black, white).

6. Avoid incorrect wiring.

If the connections are reversed (power supply line + a
power supply line –), the switch will be protected by
protection circuit. However, if the power supply line (–)
connected to the black, white wire, the switch will b

Wiring

Warning

Warning

Operating Environment

1. Perform the following maintenance periodical
in order to prevent possible danger due t
unexpected trimmer auto switch malfunction

1) Secure and tighten switch mounting screws.

If screws become loose or the mounting position
dislocated, retighten them after readjusting the mounti
position.

2) Confirm that there is no damage to lead wires.

To prevent faulty insulation, replace switches or repair lea
wires, etc., if damage is discovered.

Maintenance

1. Never use in an atmosphere with explosive
gases.

The structure of trimmer auto switches is not designed to
prevent explosion. Never use in an atmosphere with an
explosive gas since this may cause a serious explosion.

2. Do not use in an area where a magnetic field
is generated.

Trimmer auto switches will malfunction or magnets inside
cylinders will become demagnetized.

3. Do not use in an environment where the
trimmer auto switch will be continually
exposed to water.

Although the sensor units of trimmer auto switches satisfy the
IEC standard IP67 structure (JIS C0920: watertight
construction), do not use trimmer auto switches in applications
where continually exposed to water splash or spray. Poor
insulation or swelling of the potting resin inside switches may
cause malfunction.
(Amplifier part D-RNK and RPK: IP40)

4. Do not use in an environment with oil or
chemicals.

Consult SMC if auto switches will be used in an environment
with coolant, cleaning solvent, various oils or chemicals. If
auto switches are used under these conditions for even a
short time, they may be adversely affected by improper
insulation, malfunction due to swelling of the potting resin, or
hardening of the lead wires.

5. Do not use in an environment with temperature
cycles.

Consult SMC if switches are used where there are
temperature cycles other than normal temperature changes,
as they may be adversely affected.

6. Do not use in an area where surges are
generated.

When there are units (solenoid type lifter, high frequency
induction furnace, motor, etc.) which generate a large amount
of surge in the area around cylinders with trimmer auto
switches, this may cause deterioration or damage to the
circuit element inside the switch. Take measures against
sources of surge generation and take caution to crossed lines.

7. Avoid accumulation of iron powder or close
contact with magnetic substances.

When a large amount of ferrous powder such as machining
chips or spatter is accumulated, or a magnetic substance is
brought into close proximity with an auto switch cylinder, it
may cause the auto switch to malfunction due to a loss of the
magnetic force inside the cylinder.

8. Take measures against freezing when
operating at 5°C or less.

1. Consult SMC concerning water resistance
elasticity of lead wires, and usage at weldin
sites, etc.
