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.
