Precautions
Refer to pages 26 to 31 for common precautions.
Terminal Connection
When soldering the lead wire to the terminal, first insert the lead wire
conductor through the terminal hole and then conduct soldering.
Make sure that the capacity of the soldering iron is 60 W maximum.
Do not take more than 5 s to solder the switch terminal. Improper
soldering involving an excessively high temperature or excessive
soldering time may deteriorate the characteristics of the Switch.
When soldering the lead wire to the PCB terminal, pay careful atten-
tion so that the flux and solder liquid level does not exceed the PCB
level.

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
Turn OFF the power supply before mounting or removing the
Switch, wiring, or performing maintenance or inspection. Failure to
do so may result in electric shock or burning.
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 S m {2.3 to 2.7 kgf S cm}.
Mount the Switch onto a flat surface. Mounting on an uneven sur-
face may cause deformation of the Switch, resulting in faulty opera-
tion or breakage in the housing.
Operating Stroke Setting
Take particular care in setting the operating stroke for the pin plung-
er models. Make sure that the operating stroke is 70% to 100% of
the rated OT distance. Do not operate the actuator exceeding the
OT distance, otherwise the durability of the Switch may be short-
ened.
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 oper-
ate in the following range. However, even when using micro load
models within the operating range shown below, if inrush current oc-
curs when the contact is opened or closed, it may increase contact
wear and so decrease durability. Therefore, insert a contact protec-
tion circuit where necessary.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability lev-
el of 60% (λ 60). The equation, λ 60 = 0.5 10
cates that the estimated malfunction rate is less than 1/2,000,000
operations with a reliability level of 60%.
