GUIDELINES FOR USAGE
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
mounted on soft or flexible materials, panel
attachment may not be strong enough. Be sure to
thoroughly check under actual operating conditions.
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
500 mA 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.
