Precautions
★Please refer to "Common Precautions" for correct use.
●Soldering
• Complete the soldering at the iron tip temperature below
350°C within 5 seconds, and do not apply any external force
for 1 minute after soldering. Soldering at an excessively high
temperature or soldering for more than 5 seconds may
deteriorate the characteristics of the Switch.
• Be sure to apply only the minimum required amount of flux.
Switch may have contact failures if flux intrudes into the
interior of the Switch.
• If the PCB terminal models are soldered in the solder bath, flux
will permeate inside the Switch and cause contact failure.
Therefore, manually solder the PCB terminal.
●Mounting
• Use M2.3 mounting screw 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}.
• Mount the Switch onto a flat surface. Mounting on an uneven
surface may cause deformation of the Switch, resulting in
faulty operation or breakage in the housing.
●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 following operating range, if inrush
current occurs when the contact is opened or closed, it may
increase the contact wear and so decrease durability. Therefore,
insert a contact protection circuit where necessary. The N-level
reference value applies for the minimum applicable load. This
value indicates the malfunction reference level for the reliability
level of 60% (λ
60).
(JIS C5003)
The equation, λ
60=0.5×10
-6
/operation indicates that the
estimated malfunction rate is less than operations with
a reliability level of 60%.
