For details, refer to the
Proximity Sensors Technical Guide.
*2.
When using
a no-polarity model, there is no need to
be
concerned about
whether
to connect to the positive or negative side of the power supply. The load can
be
connected to either the +V side or 0 V side.

Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.
*3. The residual
voltage
of each E2EH-X@D@ DC 2-Wire Model is 5 V.
When
connecting to a device, make sure that the device can
withstand
the residual

*5. IP69K Degree of Protection Specification
IP69K is a protection standard against high temperature and high-pressure
water
defined in the German standard DIN 40050,
Part 9. The test piece is sprayed
with water
at
80°C
at a
water
pressure of
80
to 100 BAR
using
a specified nozzle shape at a
rate of 14 to 16 liters/min.
The distance
between
the test piece and nozzle is 10 to 15 cm, and
water
is sprayed horizontally for 30 seconds each at 0°,
30°, 60°, and 90°
while
rotating the test piece on a horizontal plane.
