IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against ...
IEC 60309-2 connectors come in IP44 (splash-proof), IP67 (waterproof) and IP66/IP67 (jet-proof/waterproof) variants. In all cases, the rating applies when detached or mated, but not during the mating process. The more common IP44 variant features a spring-loaded hinged cap over the socket.
Each is rated to protect against personal access to hazardous parts, and additional type-dependent designated environmental conditions. A typical NEMA enclosure might be rated to provide protection against environmental hazards such as water , dust , oil or coolant or atmospheres containing corrosive agents such as acetylene or gasoline .

IP68 — Solid particle (dust) protection level 6 (protection from all dust) and liquid ingress (waterproof) protection level 8 (protection from full immersion at depths determined by the manufacturer). [6] [8] IP69K — In the IEC 60529 rating system for ingress protection (IP), IP6* refers to the
These cable glands consist of three parts (two gland halves and a split sealing grommet) which are screwed with a hexagonal locknut (like normal cable glands). Thus, pre-assembled cables can be routed without removing the plugs. Split cable glands can reach an ingress protection of up to IP66/IP68 and NEMA 4X.
Many items of EEx rated equipment will employ more than one method of protection in different components of the apparatus. These would be then labeled with each of the individual methods. For example, a socket outlet labeled EEx'de' might have a case made to EEx 'e' and switches that are made to EEx 'd'.
NEMA contact ratings are how much current at a rated voltage a relay or other pilot device can switch. The current rating of smaller NEMA contactors or their auxiliaries are defined by NEMA ICS 5: Industrial Control and Systems, Control Circuit and Pilot Devices [1] standard. The nomenclature is a letter followed by a three-digit number, the ...
