Precautions
Use the Switch within the specified electrical ratings. Using the
Switch outside of the rated values will not only shorten its service life
but may cause heat generation or fire damage. When turning the
power ON or OFF, use the rated voltage and current.
■ Enclosure Ratings
Do Not Use the Switch Underwater
The Switch was tested and found to meet the conditions necessary
to meet the following standard. The test checks for water intrusion
after immersion for a specified time period. The test does not check
for switching operation underwater.
IEC Publication 529, degree of protection IP67.
Protection Against Chemicals
Prevent the Switch from coming into contact with oil or chemicals, to
avoid damaging (or deterioration of) Switch materials.
■ Mounting
Preparation for Mounting
Turn the power OFF before (1) mounting or removing the Switch, or
(2) before performing maintenance or inspection. Failure to do so can
cause electrical shock or fire.
Mount the Switch on a flat surface. If it is mounted on an uneven sur-
face the Switch may bend, causing a malfunction or cracking the
housing.
Mounting the Switch
Mount the switch securely, using an M4 screw with a flat washer or
spring washer. Tighten the screw to a torque of 1.18 to 1.47 N S m.
When mounting the switch, do not apply any external pressure to the
actuator in a direction other than the direction of operation.
The following diagram shows the mounting hole dimensions.
Mounting Holes
■ Operation
Make sure that the switching object is perfectly separated from the
actuator when the switch is not operated and the actuator is pressed
appropriately by the switching object when the switch is operated.
The switching object must not move beyond its operational limit posi-
tion.
Position the switching object so that its moving direction is the same
as that of the actuator.
■ Using the Switch with Micro
Loads
Even when the Switch is used within the appropriate operating
range, power surges may shorten its service life. Insert a contact pro-
tection circuit as required.
Micro application loads are indicated by N standard reference values.
This value represents the failure rate at a 60% ( λ 60) reliability level.
(JIS C5003)
The equation λ 60 = 0.5 x 10 -6 /operations indicates that a failure rate
of 1/2,000,000 operations can be expected at a reliability level of
60%.
