Terms and Conditions of Sale
1. Offer; Acceptance. These terms and conditions (these "Terms") are deemed
part of all quotations, acknowledgments, invoices, purchase orders and other
documents, whether electronic or in writing, relating to the sale of products or
services (collectively, the "Products") by Omron Electronic Components LLC
("Seller"). Seller hereby objects to any terms or conditions proposed in
Buyer's purchase order or other documents which are inconsistent with, or in
addition to, these Terms.

shall retain a security interest in the Products until the full purchase price is
paid by Buyer;
4. Delivery and shipping dates are estimates only.
5. Seller will package Products as it deems proper for protection against
normal handling and extra charges apply to special conditions.
11. Claims. Any claim by Buyer against Seller for shortage or damage to the
Products occurring before delivery to the carrier must be presented in writing

twelve months from the date of sale by Seller (or such other period expressed
in writing by Seller). Seller disclaims all other warranties, express or implied.
(b) Limitations. SELLER MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, ABOUT NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS.
BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE
PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR
INTENDED USE. Seller further disclaims all warranties and responsibility of
any type for claims or expenses based on infringement by the Products or otherwise of any intellectual property right. (c) Buyer Remedy. Seller's sole obligation hereunder shall be to replace (in the form originally shipped with Buyer
responsible for labor charges for removal or replacement thereof) the noncomplying Product or, at Seller's election, to repay or credit Buyer an amount
equal to the purchase price of the Product; provided that in no event shall
Seller be responsible for warranty, repair, indemnity or any other claims or
expenses regarding the Products unless Seller's analysis confirms that the
Products were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of
any Products by Buyer must be approved in writing by Seller before shipment.
Seller shall not be liable for the suitability or unsuitability or the results from the
use of Products in combination with any electrical or electronic components,
circuits, system assemblies, or any other materials or substances or environments. Any advice, recommendations or information given orally or in writing
are not to be construed as an amendment or addition to the above warranty.
13. Limitation on Liability; Etc. SELLER SHALL NOT BE LIABLE FOR SPECIAL,
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSS OF
PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS BASED IN
CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY. Further, in
no event shall liability of Seller exceed the individual price of the Product on
which liability is asserted.
14. Indemnities. Buyer shall indemnify and hold harmless Seller, its affiliates and
its employees from and against all liabilities, losses, claims, costs and
expenses (including attorney's fees and expenses) related to any claim, investigation, litigation or proceeding (whether or not Seller is a party) which arises
or is alleged to arise from Buyer's acts or omissions under these Terms or in
any way with respect to the Products. Without limiting the foregoing, Buyer (at

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 our
website for current information.
