What is the degree of protection IP21 and IP54?
IP21 is a classification that is part of the IP (Ingress Protection) code used to classify and define the degree of protection of an enclosure or electrical device against the ingress of solid particles and water. The acronym "IP" stands for "Ingress Protection," and is followed by either two digits or a letter and a digit. In the case of "IP21" the number "2" represents protection against the ingress of solid particles, while the number "1" indicates protection against the ingress of water droplets. Here is what it means in detail: 1. Protection against solid particles (initial digit '2'): A '2' indicates that the casing or device has limited protection against the ingress of solid particles larger than 12.5 millimetres in diameter. This means that the object is protected against solid objects of significant size, such as fingers or other relatively large particles. 2. Protection against water (final digit '1'): A '1' indicates that the casing or device is protected against the ingress of falling vertical drops of water. However, it is not considered completely waterproof.§In general, the IP rating is used to classify electrical and electronic equipment and to ensure that it is suitable for specific applications and environments. The 'IP21' classification suggests that the device has limited protection against the ingress of large solid particles and water droplets, but is not suitable for conditions where it might be exposed to moisture or significant water splashes. IP protection can vary from 'IP00' (no protection) to 'IP68' (complete protection against dust ingress and water immersion). The 'IP54' classification is part of the IP (Ingress Protection) code used to classify and define the degree of protection of an enclosure or electrical device against the ingress of solid particles and water. The acronym "IP" stands for "Ingress Protection," and is followed by two digits. In the case of "IP54," the digit "5" represents protection against the ingress of dust or solid particles, while the digit "4" indicates protection against the ingress of water droplets. Here is what it means in detail: 1. Protection against solid particles (initial figure '5'): The figure '5' indicates that the casing or device has fairly solid protection against the ingress of dust. It is considered quite protected from solid particles of significant size. 2. Protection against water (final digit '4'): A '4' indicates that the casing or device is protected against splashing water from all directions. However, it is not completely waterproof. The IP54 rating suggests that the device is quite robust against dust ingress and can withstand water splashes from different directions, but it is not suitable for water immersion or extremely wet environments. This classification is common for electronic devices that will be used in environments where some level of exposure to moisture or dust may occur, but are not exposed to extreme weather conditions or immersion in water.
