Technical Information
Degree of protection
Electrical devices to which connectors belong to 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 its 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:
IP 65
Code letters
(Internat. 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)
The following charts 4 and 5 give an overview about all protection degrees.

The probe, sphere of 50mm
Ø, shall not fully penetrate
and shall have adequate
clearance from hazardous
parts.
The jointed test finger of
12mm Ø, 80mm length,

from hazardous parts. The
probe, sphere of 12,5mm Ø,
shall not fully penetrate.
The probe of 2,5mm Ø shall
not penetrate at all.
The probe of 1mm Ø shall
not penetrate at all.
The probe of 1mm Ø shall
not penetrate.
Intrusion of dust is not
totally prevented, but dust
shall not penetrate in a
quantity to interfere with
satisfactory operation of the
device or to impair safety.
The probe of 1mm Ø shall
not penetrate.
No intrussion of dust.
