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
■ Caution
Mounting
Electrical Ratings
The cover has the same electrical potential as the COM terminal. Do not
short-circuit the cover with a NO or NC terminal when mounting the
cover.
Confirm the contact load in order to select an appropriate switch rating.
Do not apply an excessive electrical load to the contacts, otherwise
the contacts may weld, resulting in a short circuit or burning.
Terminal Connection
Do not use flow soldering or hand soldering to solder terminals.
cover
Be careful of the following points. Incorrect handling may lead to
insufficient actuator return, Switch damage, or reduced durability.
• Set the operating body in line with the direction of the actuator
movement, and make sure that the operating body is completely
separate from the actuator when the Switch is in the free position (FP). When the actuator is operated from the crosswise
direction of the Switch, make sure that the corner of the operating body has a minimum radius of R1.
Conduct reflow soldering within the range shown in the terminal temperature profile below. Some reflow soldering devices have
extremely high peak values. Do a test in advance to confirm proper
soldering conditions.
Do not conduct reflow soldering more than twice. Also provide a time
interval of at least five minutes between the first and second reflow
soldering processes to allow the Switch to return to room temperature. Heating the Switch continuously (without an interval) may cause
the edges of the Switch to melt and degrade the characteristics.
When printing for a screen solder process, a 0.13-mm screen thickness is recommended.
Be sure to provide local ventilation.
R1 min
255ഒ MAX
220ഒ
Operating body
150ഒ
• Set the Switch stroke to 70% to 100% of the overtravel (the difference between the operating position and the total travel position).
Preheating time:
60 to 120 s
• Do not subject the Switch to operations that involve strong impact.
• Do not use the Switch as a stopper.
• Do not apply excessive loads to the cover or operate the
actuator from a direction other than a specified operating
direction.
• Do not use an adhesive to secure the Switch.
A lubricant is used in the Switch. Some of the lubricant may seep out
because the Switch does not have an airtight construction. Consider
this possibility with respect to the usage conditions when designing
or using the Switch.
Application Environment
Do not use the Switch in locations that are subject to toxic gas, silicon, excessive dust, excessive dirt, high temperatures, high humidity,
sudden temperature changes, water splashes, or oil splashes.
Otherwise, damage resulting by faulty contact of the Switch contacts,
corrosion, or other causes, or other functional faults may occur.
Printed Circuit Boards
Special attention must be paid to the handling of printed circuit
boards after a Switch has been mounted onto them. Airborne PCB
particles may penetrate the interior of the Switch when printed circuit
boards are separated by cutting. Also, do not stack printed circuit
boards that have Switches mounted on them.
Product Specification Details
This document provides only a partial list of specifications. It is recommended that you request complete drawings and specifications
prior to purchasing or using the product.
■ RoHS Directive Compliance
Models that are indicated as being RoHS compliant are free of the
following six substances.
Insulation and Wiring
Lead:
1,000 ppm max.
Be sure that the installation conditions provide a sufficient insulation
distance between Switch terminals and other metal parts, lands, etc.
Mercury:
1,000 ppm max.
Cadmium:
100 ppm max.
Cleaning
Hexavalent chromium:
1,000 ppm max.
The Switch does not have an airtight construction, and it must not be
cleaned with cleaning fluids. Malfunctions may occur if the cleaning
fluid penetrates the interior of the Switch together with flux or foreign
matter from the surface of the PCB.
PBB:
1,000 ppm max.
PBDE:
1,000 ppm max.
Confirmation with Actual Equipment
Be sure to confirm the quality of the product under the load and
environmental conditions that will be used during actual applications.

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.

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
