Precautions
Refer to General Information.
■
Degree of Protection
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 oper-
ation underwater.
IEC Publication 529, degree of protection IP67.
Protection Against Chemicals
Prevent the Switch from coming into contact with oil and chemi-
cals. Otherwise, damage to or deterioration of Switch materials
may result.
Cat. No. C097-E1-02
Cautions
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
■
Mounting
Use M2.3 mounting screws with plane washers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
0.23 to 0.26 N·m {2.3 to 2.7 kgf·cm}.
Operating Body
With the pin plunger models, set the Switch so that the plunger
can be pushed in from directly above. Since the plunger is cov-
ered with a rubber cap, applying a force from lateral directions
may cause damage to the plunger or reduction in the sealing
capability.
Handling
Handle the Switch carefully so as not to break the sealing rubber
of the plunger.
Using Micro Loads
Using a model for ordinary loads to open or close the contact of a
micro load circuit may result in faulty contact. Use models that
operate in the following range. However, even when using micro
load models within the operating range shown below, if inrush
current occurs when the contact is opened or closed, it may
increase contact wear and so decrease durability. Therefore,
insert a contact protection circuit where necessary.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60% (λ 60). The equation, λ 60 = 0.5×10
indicates that the estimated malfunction rate is less than 1/
2,000,000 operations with a reliability level of 60%.
