Order the Waterproof Packing separately if it becomes lost or
damaged.
The Waterproof Packing can be used to achieve an IP66 degree of
protection.
(Deterioration, shrinking, or hardening of the waterproof packing may
occur depending on the operating environment. Therefore, periodic
replacement is recommended to ensure the level of waterproofing
specified in IP66. The time for periodic replacement depends on the
operating environment. Be sure to confirm this point at your site.
Consider one year a rough standard. OMRON shall not be liable for
the level of water resistance if the customer does not perform periodic
replacement.)
The Waterproof Packing does not need to be attached if a waterproof
structure is not required.
