Precautions

Cautions
Correct Use
●Soldering
●Mounting
• Terminal connection
Use M2 mounting screws with plane washers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
0.08 to 0.1 N·m {0.8 to 1 kgf·cm}.
When soldering, make sure that the temperature of the
soldering iron tip is not higher than 300ꢀC, and complete the
soldering within 3 seconds. Do not apply any external force for
1 minute after soldering. Soldering at an excessively high
temperature or soldering for more than 3 seconds may
deteriorate the characteristics of the Switch.
●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
minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60ꢁ (λ60).
• Connecting to PCB terminal Boards
When using automatic soldering baths, we recommend
soldering at 260ꢀC 5ꢀC within 5 seconds. Make sure that the
liquid surface of the solder does not flow over the edge of the
board.
When soldering terminals manually, perform soldering within 3
seconds at iron tip temperature not higher than 350ꢀC. Do not
apply any external force for at least 1 minute after soldering.
When applying solder, keep the solder away from the case of
the Switch and do not allow solder or flux to flow into the case.
(JIS C5003)
The equation, λ60=0.5×10-6/operation, indicates that the
1
estimated malfunction rate is less than
with a reliability level of 60ꢁ.
