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.
■ Correct Use
■ Cautions
Mounting
Terminal Connection
Turn OFF the power supply before mounting or removing the switch,
wiring the switch, or performing maintenance or inspection. Failure to
do so may result in electric shock or burning.
When soldering a lead wire to the terminal, first insert the lead wire
conductor into the terminal hole and then perform soldering.
Mount the switch onto a flat surface. Mounting on an uneven surface
may cause deformation of the switch, resulting in faulty operation or
breakage of the housing.
Make sure that the capacity of the soldering iron is 30 W maximum
and that the temperature of the soldering tip is approximately 300 °C.
(350 °C maximum.) Complete soldering within 3 s. After soldering,
do not apply external force to the soldered area for about 1 minute.
Allow sufficient insulation distance between terminals, terminal
traces and between terminals and ground.
Using a switch with improper soldering may result in abnormal heating, possibly resulting in a burn.
Operating Stroke Setting
Applying the soldering iron for more than 3 s or using an iron that is
rated for more than 30 W may deteriorate the switch characteristics.
Take particular care in setting the operating stroke for the pin plunger
models. 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 service life of the switch maybe decreased.
When soldering the lead wire to the PCB terminal, pay careful
attention so that the flux and solder liquid level does not exceed the
PCB level.
Using Microloads
Voltage (V)
Using a model for ordinary loads to switch microloads may result in
faulty operation. Instead, use the models that are designed for microloads and that operate in the following range;
Operating range
for micro load
models D2F-01
Operating
range for
general-load
models
D2F
Inoperable
range
Current (mA)
However, even when using microload models within the operating
range shown above, if inrush current or inductive voltage spikes
occur when the contact is opened or closed, it may increase contact
wear and so decrease the service life. Therefore, insert a contact
protection circuit where necessary.

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) 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.
(iii) Use in consumer products or any use in significant quantities.
(iv) Systems, machines and equipment that could present a risk to life or
property. Please know and observe all prohibitions of use applicable to this
product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Seller shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
3. Performance Data. Performance data given in this publication is provided as
a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Seller's test conditions, and the users must
correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. 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 part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
6. RoHS Compliance. Where indicated, our products currently comply, to the
best of our knowledge as of the date of this publication, with the requirements
of the European Union's Directive on the Restriction of certain Hazardous
Substances ("RoHS"), although the requirements of RoHS do not take effect
until July 2006. These requirements may be subject to change. Please consult
