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: 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)

1 Protected against vertically
falling water drops
Vertically falling drops shall
have no harmful effects.
2 Protected against vertically
falling water drops when
enclosure tilted up to 15°
Vertically falling drops shall
have no harmful effects when
the enclosure is tilted at any
angle up to 15° on either side
of the vertical.
3 Protected against spraying
water
Water sprayed at an angle
upto 60° on either side of the
vertical shall have no harmful
effects.
4 Protected against splashing
water
Water splashed against the
enclosure from any direction
shall have no harmful effects.
5 Protected against water jets Water projected in jets
against the enclosure from
any direction shall have no
harmful effects.
6 Protected against powerful
water jets
Water projected in powerful
jets against the enclosure
from any direction shall have
no harmful effects.
7 Protected against the effects
of temporary immersion in
water
Intrusion of water in
quantities causing harmful
effects shall not be possible
when the enclosure is
temporalily immersed in water
for 30 min. in 1m depth.
8 Protected against the effects
of continous immersion in
water
Intrusion of water in quantities
causing harmful effects shall
not be possible when the
enclosure is continuously
immersed in water under
conditions which shall be
agreed between manufacturer
and user but which are more
severe than for numeral 7.
