Characteristics

Note: 1.

The data given above are initial values.

The dielectric strength shown in the table indicates a value for models with a Separator.

For the pin plunger models, the above values apply for both the free position and total travel position. For the lever models, the values
apply at the total travel position. Contact opening or closing time is within 1 ms.

Precautions

Cautions

Connecting to Solder Terminals

When soldering the lead wire to the terminal, first insert the lead wire
conductor through the terminal hole and then solder.

Make sure that the temperature at the tip of the soldering iron is 350
to 400

°C. Do not take more than 3 seconds to solder the switch ter-

minal, and do not impose external force on the terminal for 1 min
after soldering. Improper soldering involving an excessively high tem-
perature or excessive soldering time may deteriorate the characteris-
tics of the Switch.

Connecting to Quick-connect
Terminals

Wire the quick-connect terminals (#110) with receptacles. Insert the
terminals straight into the receptacles. Do not impose excessive
force on the terminal in the horizontal direction, otherwise the termi-
nal may be deformed or the housing may be damaged.

Connectors

Use the following quick-connect connector made by Nippon Tanshi or
Tyco Electronics. This connector is not sold by OMRON. Contact the
following Nippon Tanshi or Tyco Electronics office to purchase this
connector.

This connector is for use with the SS-P and the terminal direction is
90

° different from the SS Series. Individual quick connect recepta-

cles are common to both types.

Connecting to PCB Terminal Boards

When using automatic soldering baths, we recommend soldering at
260

±5°C within 5 seconds. Make sure that the liquid surface of the

solder does not flow over the edge of the board.

When soldering by hand, as a guideline, solder with a soldering iron
with a tip temperature of 350 to 400

°C within 3 seconds, and do not

apply any external force for at least 1 minutes after soldering. When
applying solder, keep the solder away from the case of the Switch
and do not allow solder or flux to enter the case.

Correct Use

Mounting

Turn OFF the power supply before mounting or removing the Switch,
wiring, or performing maintenance or inspection. Failure to do so may
result in electric shock or burning.

Use M2.3 mounting screws with plane washers or spring washers to
securely mount the Switch. Tighten the screws to a torque of 0.23 to
0.26 N·m {2.3 to 2.7 kgf·cm}.

Mount the Switch onto a flat surface. Mounting on an uneven surface
may cause deformation of the Switch, resulting in faulty operation or
breakage in the housing.

Operating Stroke Setting

Take particular care in setting the operating stroke for the pin plunger
models. Make sure that the operating stroke is 60% to 90% of the
rated OT distance. Do not operate the actuator exceeding the OT dis-
tance, otherwise the life expectancy of the Switch may be shortened.

Using Micro Loads

Using a model for ordinary loads to open or close the contact of a
micro load circuit may result in faulty contact. Use models that oper-
ate in the following range. However, even when using micro load
models within the operating range shown below, if inrush current
occurs when the contact is opened or closed, it may increase contact
wear and so decrease life expectancy. Therefore, insert a contact
protection circuit where necessary.

The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability level
of 60% (

). The equation,

= 0.5 × 10

-6

/operations indicates that

the estimated malfunction rate is less than 1/2,000,000 operations
with a reliability level of 60%.

invoices sent to Buyer after deducting transportation charges, taxes and
duties, and will be allowed only if (i) the invoice is paid according to Seller's
payment terms and (ii) Buyer has no past due amounts owing to Seller.

4. Currencies. If the prices quoted herein are in a currency other than U.S. dol-

lars, Buyer shall make remittance to Seller at the then current exchange rate
most favorable to Seller and which is available on the due date; provided that if
remittance is not made when due, Buyer will convert the amount to U.S. dol-
lars at the then current exchange rate most favorable to Seller available during

Certain Precautions on Specifications and Use

1. Suitability for Use. Seller shall not be responsible for conformity with any stan-

dards, 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 pro-
vide applicable third party certification documents identifying ratings and limita-
tions 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 combi-
nation with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the partic-
ular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a non-
exhaustive 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 corre-
late 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 prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for your
application. Please consult with your Seller representative at any time to con-
firm 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 Sub-
stances ("RoHS"), although the requirements of RoHS do not take effect until
July 2006. These requirements may be subject to change. Please consult our
website for current information.
