free from defects in workmanship and materials, under normal use and service, for the
applicable warranty term. All SMC products carry a standard 90-day limited warranty from

The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering
new products within 30 days of purchase from SMC or its Authorized Reseller. Registration
can be accomplished via the enclosed product registration card or online via the SMC web

warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:

either new or reconditioned. Any replaced or repaired product carries either a 30-day limited
warranty or the remainder of the initial warranty, whichever is longer. SMC is not responsible
for any custom software or firmware, configuration information, or memory data of
Customer contained in, stored on, or integrated with any products returned to SMC pursuant
to any warranty. Products returned to SMC should have any customer-installed accessory or

replacement. SMC is not responsible for these items if they are returned with the product.
Customers must contact SMC for a Return Material Authorization number prior to returning
any product to SMC. Proof of purchase may be required. Any product returned to SMC
without a valid Return Material Authorization (RMA) number clearly marked on the outside
of the package will be returned to customer at customer’s expense. For warranty claims within
