Protection against water
spray
Protects against water spray
approaching at any angle
towards the product.
Water is sprayed at any
angle towards the product
for 10 min from the test
machine.
5
Protection against water
jet spray
Protects against water jet
spray approaching at any
angle towards the product.
Water is jet sprayed at any
angle towards the product
for 1 min per square meter
for at least 3 min in total
from the test machine.
6
Protection against high
pressure water jet spray
Protects against high-
pressure water jet spray
approaching at any angle
towards the product.
Water is jet sprayed at any
angle towards the product
for 1 min per square meter
for at least 3 min in total
from the test machine.
7
Protection against limited
immersion in water
Resists the penetration of
water when the product is
placed underwater at
specified pressure for a
specified time.
The product is placed 1 m
deep in water (if the product
is 850 mm max. in height)
for 30 min.

(See note.)
Protection against long-
term immersion in water
Can be used continuously
underwater.
The test method is
determined by the
manufacturer and user.
Note: OMRON Test Method
Usage condition: 10 m or less under water in natural conditions
1. No water ingress after 1 hour under water at 2 atmospheres of pressure.
2. Sensing distance and insulation resistance specifications must be met after 100 repetitions of half hour in 5
°
C water
and half hour in 85
°
C water.
About IPX9K
IPX9K is a protection standard regarding high temperature and high-pressure water which is
defined by the German standard (DIN 40050 PART9).
Water is sprayed on 80
°
C hot water with the water pressure of 80 to 100BAR from a nozzle to the
test piece.
Amount of water is 14 to 16 liters/minute.
The distance between the test piece and a nozzle is 10 to 15 cm, and the directions of water-
drainage are 0 degrees, 30 degrees, 60 degrees, and 90 degrees horizontally.
They are evaluated with the test piece is rotating on a horizontal plane by 30 seconds in each
direction.
Protection
Oil-resistant
No adverse affect from oil drops or oil spray approaching from any direction.
Oil-proof
Protects against penetration of oil drops or oil spray approaching from any direction.
Note.
Oil resistance has been tested using a specific oil as defined in the OMRON test method. (JIS C 0920:2003, Appendix 1)
