(Ingress Protection)

Degree of protection

Electrical devices to which connectors belong have to be protected for safety reasons from outside influences like dust, foreign objects, direct contact, moisture

and water. This protection is provided on industrial connectors by their housings with their latching devices and sealed cable entries.

The degree of protection can be selected depending on the type of intended use. The standard IEC 60529 and/or DIN EN 60529 has specified the degree of

protection and divided into several classes.

The degree of protection is indicated in the following way:

Code letters

(Ingress Protection)

1st charact. numeral (degree of protection against access

to hazardous parts and against solid foreign objects)

2nd charact. numeral (degree of protection against ingress of water)
