Operating Environment
•
The Switch does not have a water-resistant structure. Take
measures to protect the Switch if it is to be used in locations subject
to splashing or spraying water or other liquids.
•
Do not use the Switch where it is continuously subjected to vibration
or shock. Doing so will result in contact failure, malfunction, or a
decrease in service life caused by abrasive powder that is
generated from the internal parts. Subjecting the Switch to
excessive vibration or shock may cause the contacts to
malfunction, stick, or become damaged. Make sure to install the
Switch in locations free of vibration or shock or in a direction where
resonance will not occur.
•
Do not use the Switch in locations subject to corrosive gas, such as
sulfuric gas (H
2
S or SO
2
), ammonium gas (NH
3
), nitric gas (HNO
3
),
or chlorine gas (Cl
2
), or high temperature and humidity.
Doing so will result in damage due to contact failure or corrosion.
•
If the Switch is used in locations with silicone gas, arc energy may
cause silicon dioxide (SiO
2
) to build up on the contacts and contact
failure may result. If there is silicone oil, silicone sealant, or wire
covered with silicone close to the Switch, attach a contact
protective circuit to suppress the arcing of the Switch or eliminate
the source of silicone gas.
•
Use the switch within the specified range for operating temperature
and humidity. Using the Switch in high temperatures will cause the
operating characteristics to deviate. Rapid changes in temperature
will also cause the operating characteristics to deviate. It is
recommended to install the Switch as far as possible from heat
sources so that the temperature of the Switch is not affected.

uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
•
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
•
Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
•
Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE

CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
