* 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. (Models for Connectors: A Connector is not provided with the Sensor. Be sure to order a Connector separately.)

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.
