The first digit represents the level of protection against solid bodies such as dust, and the second digit does the degree of protection against water. For example, IP68 means no ingress of dust, no water ingress >1m, >30mins.

IP-16 series supports from 4.8mm to 11.0mm cable OD.

When the bayonet collar is fully engaged in lock position, the Safe Lock Ring can be slid up to avoid unintentional engagement.
