SSG Subminiature Basic Switch
Precautions
Refer to General Information.
● Terminal Connection
When soldering the lead wire to the terminal, first insert the lead
wire conductor through the terminal hole and then take the
following steps promptly.
• Make sure that the capacity of the soldering iron is 60 W
(temperature of soldering iron : 350 to 400°C) maximum. Do
not take more than 3 s to solder the switch terminal. Improper
soldering involving an excessively high temperature or
excessive soldering time may deteriorate the characteristics of
the
Switch.
• Be sure to apply only the minimum required amount of flux.
The SSG may have contact failures if flux intrudes into the
interior of the SSG.
• Use the following lead wires to connect to the solder terminals.
260+/-5°C for 5 seconds max. is recommended for flow
soldering. Overflow of solder or flux should be avoided.
Wire the quick-connect terminals (#110) with receptacles. Insert
the terminals straight into the recept
acles. Do not impose
excessive force on the terminal in the horizontal direction,
otherwise the terminal may be deformed or the housing may be
damaged.
● Insulation Distance
The Switch does not have a ground terminal. According to
EN61058-1, the minimum insulation thickness for this Switch
should be 0.9 mm. If the insulation distance cannot be provided
in the product incorporating the Switch, either use a Switch with
insulation barrier or use a Separator to ensure sufficient
insulation distance.
● Mounting
Use M2.2 mounting screws with plane washers or spring
washers to securely mount the Switch. Tighten the screws to a
torque of 0.20 to 0.24 N·m {2 to 2.5 kgf·cm}.
● Operating Stroke
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
shortened.
● 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
–6
/operations
indicates that the estimated malfunction rate is less than
1/2,000,000 operations with a reliability level of 60%.
