Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,
“Snap Action Switches, Technical Information” for correct use.
■ Protection against chemicals
■ Degree of Protection
Prevent the switch from coming into contact with oil and chemicals.
Otherwise, damage to or deterioration of switch materials may result.
Because the switch uses polycarbonate resin as material for its com-
ponent parts, contact OMRON if the switch material is likely to deteri-
orate due to adherence of oil or chemicals to the switch housing.
The D2JW satisfies the following test condition specified by the IEC
Publication 529 (Degree of Protection by Enclosure):
Degree of protection: IP67
Test method: See the figure below.
■ Soldering
To solder the lead to the terminal, apply a soldering iron rated at
30 W max. (temperature of soldering iron: 250°C max.) for no more
than 3 seconds.
Note that if soldering is not carried out under the proper conditions, there
is a danger of over-heating and subsequent heat damage.
Applying a soldering iron for more than three seconds or using one that
is rated at more than 30 W may degrade the switch characteristics.
■ Operation
Make sure that the operating body pushes the switch actuator with
an adequate force when the switch is to be operated, and that it does
not touch the actuator when the switch is released.
Install the pin plunger switch so that the operating force is applied in
alignment with the stroke of the actuator.
Do not apply excessive force to the actuator; otherwise, the switch
may be damaged.
Leave the test piece in water for 30 minutes with the top of the test
piece submerged 15 cm or more below the water level and the bot-
tom of the test piece submerged 1 m or more below the water level.
This test is to check the ingress of water into the switch enclosure
after submerging the switch in water for a given time. Note that even
if this test condition is met, the switch cannot be used in water.
■ Separator
When mounting the switch on a metallic surface, be sure to provide a
separator between the switch and the mounting plates.
Reference the following dimensions when designing the separator;
