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.
■ Oil Resistance (OMRON in-house standard)
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)

Outline of test methods (tests using water)
Using the test apparatus
shown in the figure to the
right, water is sprayed
from both directions, onto
both sides of the product,
at angles up to 60° from
vertical for 10 minutes.
Using the test apparatus
shown in the figure to the
right, water is splashed
onto the product from all
directions for 10 minutes.
Using the test apparatus
shown in the figure to the
right, a water jet is directed
at the product from all
directions for 1 minute per
square meter of outer cas-
ing, with a minimum total
exposure of 3 minutes.
Using the test apparatus
shown in the figure to the
right, a water jet is directed
at the product from all
