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.
