IP codes 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 ...
Before the advent of the IK code, a third numeral had been occasionally added to the closely related IP Code on ingress protection, to indicate the level of impact protection — e.g. IP66(9). Nonstandard use of this system was one of the factors leading to the development of this standard, which uses a separate two numeral code to distinguish ...
Cable glands and self-sealing grommets are usually designed for entering single or just a few cables. By utilising a gland plate, many cables with different diameters can be routed. Depending on the type, very high cable densities or ingress protection classes up to IP66/IP68 (according to IEC 60529) can be achieved.
Split cable glands can reach an ingress protection of up to IP66/IP68 and NEMA 4X. Alternatively, split cable entry systems can be used (normally consisting of a hard frame and several sealing grommets) to route a large number of pre-terminated cables through one wall cut-out.
