       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 voltage. (Refer to Data Sheet.)

       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.
