Getting the right IP rating for your industrial electronic enclosures is crucial. Get it wrong and you risk making a very expensive mistake. IP ratings (and their US NEMA equivalents) are only the start of the specifying journey but they are a vital first step…
There are many standards of ‘waterproof’ so make sure your IP rating is the right one for your electronics. If in doubt, play safe. Over-specification is always better than trying to squeak by on a lower IP rating. It’s just not worth the risk.
The first digit of the IP rating needs to start with a ‘6’. That guarantees complete protection from dust ingress.
The second digit determines water ingress. Industrial electronic enclosures are usually rated IP 65 or higher:
But remember – all that protection could be compromised if you have to remove the lid when installing the enclosure in foul weather or other challenging environments.
It’s easy to pigeonhole materials – plastic for indoor, metal for outdoor – but that’s missing a trick. There’s much more to it than that. And plenty of opportunities to be gained by digging deeper:
Optional key locks on your enclosures enable easy opening for servicing and maintenance but prevent tampering. Popular models such as aluCASE (IP66/67/69k) offer a lid key lock and a choice of either integrated retaining straps or hinges with no visible fixing screws. Like the easy click-to-fit of aluCLIC (IP67/69k) but want more security? Specify its more secure brother aluSMART (IP67/69k) which features a similar mounting bracket but with screw-in installation.
