1. Avoid repeatedly bending or stretching lead
2. Be sure to connect the load before power is
3. Confirm proper insulation of wiring.
4. Do not wire with power lines or high voltage
5. Do not allow short circuiting of loads.
1. Do not drop or bump.
2. Do not carry a cylinder by the auto switch lead
3. Mount switches using the proper tightening
4. Mount a switch at the center of the operating
Do not drop, bump, or apply excessive impacts (300 m/s
more for reed switches and 1000 m/s
switches) while handling. Although the body of the switch may
not be damaged, the inside of the switch could be damaged
and cause a malfunction.
wires.
Never carry a cylinder by its lead wires. This may not only
cause broken lead wires, but it may cause internal elements of
the switch to be damaged by the stress.
torque.
When a switch is tightened beyond the range of fastening
torque, the mounting screws or switch may be damaged.
On the other hand, tightening below the range of fastening
torque may alllow the switch to slip out of position. (Refer to
switch mounting for each series regarding switch mounting,
moving, and fastening torque, etc.)
range.
Adjust the mounting position of an auto switch so that the
piston stops at the center of the operating range (the range in
which a switch is ON). (The mounting positions shown in the
catalog indicate the optimum position at the stroke end.) If
mounted at the end of the operating range (around the
borderline of ON and OFF), the operation will be unstable.
wires.
Broken lead wires will result from repeatedly applying bending
stress or stretching force to the lead wires.
applied.
<2-wire type>
If the power is turned on when an auto switch is not connected
to a load, the switch will be instantly damaged because of
excess current.
Be certain that there is no faulty wiring insulation (contact with
other circuits, ground fault, improper insulation between
terminals, etc.). Damage may occur due to excess current flow
into a switch.
lines.
Wire separately from power lines or high voltage lines,
avoiding parallel wiring or wiring in the same conduit with
these lines. Control circuits including auto switches may
malfunction due to noise from these other lines.
<Reed switches>
If the power is turned on with a load in a short circuited
condition, the switch will be instantly damaged because of
excess current flow into the switch.

6. Avoid incorrect wiring.
Lead wire colors of SMC auto switches have been changed in
order to meet NECA Standard 0402 for production beginning
September, 1996 and thereafter. Please refer to the tables

Model D-F9(Y)/F9W(V)/J51/G5NB and all models of PNP
output switches do not have built-in short circuit prevention
circuits. If loads are short circuited, the switches will be
instantly damaged.
Use caution to avoid reverse wiring with the brown [red] power
supply line and the black [white] output line on 3-wire type
switches.
