sent to Buyer after deducting transportation charges, taxes and duties, and will
be allowed only if (i) the invoice is paid according to Omron’s payment terms
and (ii) Buyer has no past due amounts.
4. Interest. Omron, at its option, may charge Buyer 1-1/2% interest per month or
the maximum legal rate, whichever is less, on any balance not paid within the
stated terms.
5. Orders. Omron will accept no order less than $200 net billing.
6. Governmental Approvals. Buyer shall be responsible for, and shall bear all
costs involved in, obtaining any government approvals required for the impor-
tation or sale of the Products.
7. Taxes. All taxes, duties and other governmental charges (other than general
real property and income taxes), including any interest or penalties thereon,
imposed directly or indirectly on Omron or required to be collected directly or
indirectly by Omron for the manufacture, production, sale, delivery, importa-
tion, consumption or use of the Products sold hereunder (including customs
duties and sales, excise, use, turnover and license taxes) shall be charged to
and remitted by Buyer to Omron.
8. Financial. If the financial position of Buyer at any time becomes unsatisfactory
to Omron, Omron reserves the right to stop shipments or require satisfactory
security or payment in advance. If Buyer fails to make payment or otherwise
comply with these Terms or any related agreement, Omron may (without liabil-
ity and in addition to other remedies) cancel any unshipped portion of Prod-
ucts sold hereunder and stop any Products in transit until Buyer pays all
amounts, including amounts payable hereunder, whether or not then due,
which are owing to it by Buyer. Buyer shall in any event remain liable for all
unpaid accounts.
9. Cancellation; Etc. Orders are not subject to rescheduling or cancellation
unless Buyer indemnifies Omron against all related costs or expenses.
10. Force Majeure. Omron shall not be liable for any delay or failure in delivery
resulting from causes beyond its control, including earthquakes, fires, floods,
strikes or other labor disputes, shortage of labor or materials, accidents to
machinery, acts of sabotage, riots, delay in or lack of transportation or the
requirements of any government authority.
11. Shipping; Delivery. Unless otherwise expressly agreed in writing by Omron:
a. Shipments shall be by a carrier selected by Omron; Omron will not drop ship
except in “break down” situations.
b. Such carrier shall act as the agent of Buyer and delivery to such carrier shall
constitute delivery to Buyer;
c. All sales and shipments of Products shall be FOB shipping point (unless oth-
erwise stated in writing by Omron), at which point title and risk of loss shall
pass from Omron to Buyer; provided that Omron shall retain a security inter-
est in the Products until the full purchase price is paid;
d. Delivery and shipping dates are estimates only; and
e. Omron will package Products as it deems proper for protection against nor-
mal handling and extra charges apply to special conditions.
12. Claims. Any claim by Buyer against Omron for shortage or damage to the
Products occurring before delivery to the carrier must be presented in writing
to Omron within 30 days of receipt of shipment and include the original trans-
portation bill signed by the carrier noting that the carrier received the Products
from Omron in the condition claimed.
13. Warranties. (a) Exclusive Warranty. Omron’s exclusive warranty is that the
Products will be free from defects in materials and workmanship for a period of
twelve months from the date of sale by Omron (or such other period expressed
in writing by Omron). Omron disclaims all other warranties, express or implied.
(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, ABOUT NON-INFRINGEMENT, MERCHANTABIL-
ITY 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. Omron further disclaims all warranties and responsibility of
any type for claims or expenses based on infringement by the Products or oth-
erwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obli-
gation hereunder shall be, at Omron’s election, to (i) replace (in the form
originally shipped with Buyer responsible for labor charges for removal or
replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of
the non-complying Product; provided that in no event shall Omron be responsi-
ble for warranty, repair, indemnity or any other claims or expenses regarding
the Products unless Omron’s analysis confirms that the Products were prop-
erly handled, stored, installed and maintained and not subject to contamina-
tion, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Compa-
nies 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 environ-
ments. Any advice, recommendations or information given orally or in writing,
are not to be construed as an amendment or addition to the above warranty.
See http://www.omron247.com or contact your Omron representative for pub-
lished information.
14. Limitation on Liability; Etc. OMRON COMPANIES 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 Omron Companies exceed the individual
price of the Product on which liability is asserted.
15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and
their employees from and against all liabilities, losses, claims, costs and
expenses (including attorney's fees and expenses) related to any claim, inves-
tigation, litigation or proceeding (whether or not Omron 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
its own expense) shall indemnify and hold harmless Omron and defend or set-
tle any action brought against such Companies to the extent based on a claim
that any Product made to Buyer specifications infringed intellectual property
rights of another party.
16. Property; Confidentiality. Any intellectual property in the Products is the exclu-
sive property of Omron Companies and Buyer shall not attempt to duplicate it
in any way without the written permission of Omron. Notwithstanding any
charges to Buyer for engineering or tooling, all engineering and tooling shall
remain the exclusive property of Omron. All information and materials supplied
by Omron to Buyer relating to the Products are confidential and proprietary,
and Buyer shall limit distribution thereof to its trusted employees and strictly
prevent disclosure to any third party.
17. Export Controls. Buyer shall comply with all applicable laws, regulations and
licenses regarding (i) export of products or information; (iii) sale of products to
“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of
regulated technology or information.
18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right
and no course of dealing between Buyer and Omron shall operate as a waiver
of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder
without Omron's written consent. (c) Law. These Terms are governed by the
law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law princi-
ples). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed
or waived unless in writing signed by the parties. (e) Severability
. If any provi-
sion hereof is rendered ineffective or invalid, such provision shall not invalidate
any other provision. (f) Setoff. Buyer shall have no right to set off any amounts
against the amount owing in respect of this invoice. (g) Definitions. As used
herein, “including” means “including without limitation”; and “Omron Compa-
nies” (or similar words) mean Omron Corporation and any direct or indirect
subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron 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 Prod-
uct 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
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) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’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 Omron’s representative at any time
to confirm actual specifications of purchased Product.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
