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.

Code

First digit description

0 No special protection

1

Protection from a large part of the body such as hand

or from solid objects greater than 50 mm in diameter

2

Protection against objects not greater than 80 mm in length

and 12 mm in diameter

3

Protection from entry by tools, wires, etc.,

with a diameter or thickness greater than 2.5 mm

4

Protection from entry by solid objects

with a diameter or thickness greater than 1.0 mm

5

Protection from the amount of dust that would interfere

with the operation of the equipment

6 Dust-tight

2nd digit

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.)

Code

Second digit description

0 No special protection

1 Protection from vertically dripping water

2 Protection from dripping water when tilted up to 15°

3 Protection from sprayed water

4 Protection from splashed water

5 Protection from water projected from a nozzle

6 Protection against heavy seas, or powerful jets of water

7 Protection against temporary immersion

8 Protection against complete continuous submersion in water

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:

A) Figure 1 shows a typical outdoor device. To ensure this

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.

B) Figure 2 shows a device which is subjected to pressure

difference such as a near vacuum or pressurized gas

and must exhibit no leakage. To ensure the device

maintains its sealing, the socket is additionally tested for

helium leakage (according MIL 1344A).
