IP69K IP69K test according to DIN 40050 / part 9

  • cycle of 30 seconds
  • 14 - 16 liters per minute
  • water 80°C

The goal of this test is to simulate pressure cleaning conditions on a plant floor. In the test fixture, the switches were exposed to a water jet of 80 - 100 bar at a temperature of 80 °C.

The duration of each cleaning cycle was 30 seconds. The test was performed with a spray nozzle located at defined angles and at a distance of 10 - 15 cm from the sensor.

The high protection rating guarantees absolute ingress-resistance, even in applications subject to frequent cleaning processes, e.g. in the food industry.

 

Test conditions

  • Test with fan nozzle
  • Test unit on turntable (5 revolutions/minute)
  • Spray angles 0°, 30°, 60° and 90°
  • Distance of nozzle to test unit 100 - 150 mm
  • Spray quantity 14 to 16 litres/min.
  • Water pressure about 8,000 - 10,000 kPa at +(80 +/- 5)°C with a duration of 30 seconds per position.
  • Water aimed at the housing with increased pressure from each direction must not have any damaging effect.
