Instrument cases are usually available in both heavy-duty and more lightweight configurations, depending on the level of protection and portability required. They can be used for anything from outdoor LED power supply casings to industrial camera housings, desktop electronics and measuring/control equipment. IP rated power supply cases This isn’t always the case since most rainwater - even in windy conditions - tends to fall relatively close to vertical, and under very low pressure. An IPX2 rating should protect against dripping water equivalent to 3 mm rainfall per minute at angles up to 15°, while IPX3 indicates resistance to continuous spray at up to 60° from vertical. Protection against low-pressure jets (6.3mm) of directed water from any angle (limited ingress permitted with no harmful effects)
Protection against vertically falling droplets, such as condensation, sufficient that no damage or interrupted functioning of components will be incurred when an item is upright Handheld enclosures are protective cases for controllers and electronic instruments, widely used for both simple mobile controls and more heavy-duty electronic devices including volt-meters, digital thermometers and flow readers. The following are general industry rules of thumb for outdoor lighting, but it’s always wise to seek manufacturer or supplier advice for your specific application scenario before installation:Zone 1 indicates an area directly above a bath or shower enclosure, to a height of 2.25 metres from the floor. This would include any wall- or ceiling-mounted downlights within the vertical perimeter of a shower enclosure, for example. IP45 is technically the minimum resistance required here, although IP65 is a much more common standard, and most lighting for shower or bath areas will be rated to at least IP65 by default.
Intrusion’ in the context of an IP rating has a threefold definition: IP codes signify the level of protection to users (hands, fingers etc) from mechanical or electrical parts; the degree of protection an enclosure offers those key components against dust, dirt and other damaging foreign bodies; and its overall resistance to moisture.IP65 offers much greater protection against both solid objects and water ingress. The first digit is a 6, indicating complete protection of the highest level against dust and other fine matter. At a 5, the second digit also indicates a strong level of water protection, establishing that the part or component that has achieved this rating is protected against water jets, spraying water and vertically falling drops. While higher levels of protection are available, they are uncommon for household applications and are only typically necessary for specialised equipment or offshore use.
A product with an IP20 rating tells you that it has ingress protection up to 12.5mm against solid bodies such as fingers or dust. However, this rating also signifies that the product is not waterproof, which lets you know that it won’t be suitable for outdoor applications. Protection against full immersion for up to 30 minutes at depths between 15cm and 1 metre (limited ingress permitted with no harmful effects) Zone 2 indicates a 60cm radius around any bath or shower enclosure, and here a splash-proof rating of IP44 is the minimum requirement. (This is also commonly extended to areas around sinks, where the 0.6m measurement is usually taken from the taps themselves.)A ‘waterproof’ or ‘weatherproof’ IP rating is one of the most frequent examples people look for in a wide range of everyday products, from mobile phones and Bluetooth speakers to kitchen and bathroom fixtures, lighting setups, CCTV enclosures and more. Unlike more vague marketing terms such as ‘waterproof’ - which don’t necessarily give a clear definition of precisely where and to what extent an item can resist moisture ingress - an IP rating is designed to provide a far more specific account. The reason for having a universal IP rating system is so that buyers and users can be confident of how safe it is to use certain electrical or mechanical goods in specific environments and applications. Some installations are more challenging than others, and require components with a higher ingress protection rating that are secure from dust, foreign bodies and moisture, while in other cases a part may only need to be resistant to ingress by fingers or other body parts. Once you understand how the ingress protection rating scale works, it is simple to determine the level of protection each part offers. When the unit isn’t tailored to fit any one specific application, it’s usually crafted as a simple but sturdy box without specialist features for particular housings or contents. Sizes and construction materials will depend on their intended application and environment, but they’re commonly rated at IP65 and above for general outdoor use. IP rated handheld enclosures
