AJ8 Switches with Trip Function Upgraded Type
–4–
AECTB30E 201811-T
OPERATING PRINCIPLE
• Manual operation is a repetition of (A) and (B). This operation is independent of the electromagnetic reset function.
• The reset mechanism operates only when an electromagnetic reset has occurred. (C)

Operating voltage application time
If the rated voltage is applied to the coil
for more than 10 seconds or the
maximum voltage is applied for more
than 1 second, coil performance may
deteriorate.
■
The shape of the mounting panel
should be as recommended in the
dimensions diagram.
Please contact us if you are considering
using a panel of other than the
recommended size and shape.
■
The mounting panel should be made
of SPCC. If a different material is used,
its adhesion to the switch unit may not
be as strong. Check this with actual
application necessary.
■
Note that the actuator could come
off from the switch housing if 19.6N or
more of force is applied to the side of
the actuator.
■
Regarding fastening lead wires to
terminals
1) When connecting the .250 Quick-
connect terminals, use a .250 receptacle
and insert the terminals straight in.
If you insert them at an angle, the
terminals could catch on the opening and
will require greater insertion force.
2) The coil terminals have specific
polarities. Make sure you connect them
correctly.
3) Use a receptacle that is compliant with
JIS C 2809. In addition, there is some
deviation regarding the insertion force
depending on the model used from
different manufacturers, so the insertion
force should be checked under actual
conditions.
4) Use TE Connectivity Ltd.’s CT
connector for the coil terminals.
■
Because special receptacle
terminals are used for the contact
terminals and the common terminals,
do not attempt to solder them. Doing
so could melt plastic components and
otherwise harm the performance of
the switch
■
The terminals should be connected
in such a way that they are not under
constant stress from the connecting
wires.
■
Take care not to drop the product as
it may impair performance.
■
Resistance to chemicals
To clean the switch unit, use a neutral
detergent diluted with water.
Do not use acidic or alkaline solvents as
they may damage the switch.
Furthermore, be careful not to get any of
the detergent solution inside of the switch
while cleaning it.
■
This product is not hermetically
sealed, so its performance could
deteriorate under certain ambient
conditions. Avoid using and storing
these switches in a location where
they will be exposed to corrosive
gases, silicon, or high dust levels, all
of which can have an adverse effect
on the contacts. In addition, because
these switches contain permanent
magnets, avoid using and storing
these switches in a location where
metallic dust, etc., is present.
■
When these switches are used with
weak currents of 500mA or less, a
layer of material on the surface of the
contacts may cause contact
instability. Check and evaluate this
possibility before using these
switches under such conditions.
■
When using an ON-OFF type switch
with no (
) indication on the
actuator, the “OFF” position should be
indicated on the set in which the
switch is installed.
■
To assure reliability, check the
switch under actual loading
conditions. Avoid any situation that
may adversely affect switching
performance.
