IK Ratings Explained

What is an IK Rating?

An IK (Impact Protection) rating is a unit used to define the levels of protection an electrical enclosure offers to any contents and assemblies housed inside. This is calculated by measuring the enclosure's protection against external mechanical impacts.

To ensure your components are sufficiently protected, it’s important to understand the protection level offered from each rating and what IK rating you require for your application. An IK rating varies from 0 – 10, with IK10 offering the highest level of protection.

IK ratings are defined in international standard IEC 62262 and IEC 600608-2-75.

 

Impact Protection

00 – No impact protection
01 – Protected against 0.14 joules impact  (equivalent to the impact of 0.25kg mass dropped from 56mm high)
02 – Protected against 0.2 joules impact  (equivalent to impact of 0.25kg mass dropped from 80mm high)
03 – Protected against 0.35 joules impact  (equivalent to impact of 0.25kg mass dropped from 140mm high)
04 – Protected against 0.5 joules impact  (equivalent to impact of 0.25kg mass dropped from 200mm high)
05 – Protected against 0.7 joules impact  (equivalent to impact of 0.25kg mass dropped from 280mm high)
06 – Protected against 1 joules impact  (equivalent to impact of 0.25kg mass dropped from 400mm high)
07 – Protected against 2 joules impact  (equivalent to impact of 0.5kg mass dropped from 400mm high)
08 – Protected against 5 joules impact  (equivalent to impact of 1.7kg mass dropped from 300mm high)
09 – Protected against 10 joules impact  (equivalent to impact of 5kg mass dropped from 200mm high)
10 – Protected against 20 joules impact  (equivalent to impact of 5kg mass dropped from 400mm high)
