IP-68

The International Protection Rating (IP) classifies the degrees of protection provided against the intrusion of solid objects, dust, accidental contact, and water in electrical enclosures. The numeral 6 in IP-68 stands for protection against water from powerful jets from any direction; the numeral 8 stands for protection against immersion in over 1 meter (3 feet) of water. AMR transmitters used in manufactured housing, marinas, and RV parks must be IP-68 compliant.
