Definition of Ingress Protection (IP code)
IEC 60529 outlines an international classification system
for the sealing effectiveness of enclosures of electrical
equipment against the intrusion into the equipment of for-
eign bodies (i.e. tools, dust, fingers) and moisture. This
classification system utilizes the letters «IP» (Ingress Pro-
tection) followed by two digits.
Degrees of protection - First digit
The first digit of the IP code indicates the degree to which
persons are protected against contact with moving parts
and the degree that equipment is protected against solid
foreign bodies intruding into an enclosure.
Selection of connectors for watertight or vacuumtight devices
LEMO B and S series are rated IP50 only when mated. LEMO E, K and L series are rated IP66 (and over) only when
mated. If a device must be watertight or vacuumtight when the connectors are unmated, it is important to select a watertight
or vacuumtight socket. You can consider the following two situations:

device retains IP66 or above when connectors are
unmated, it is important to choose a watertight socket
from B, S, E, K or L series.

Degrees of protection - Second digit
The second digit indicates the degree of protection of the
equipment inside the enclosure against the harmful entry
of various forms of moisture (e.g. dripping, spraying, sub-
mersion, etc.)

and must exhibit no leakage. To ensure the device
maintains its sealing, the socket is additionally tested for
helium leakage (according MIL 1344A).
