The IP or Ingress Protection rating measures a products ability to prevent the ingress of objects, dust, water, etc… into the enclosure causing damage. The first number relates to solids while the second number relates to moisture. For example, INTEC’s cameras, displays and H and XL series controllers are rated to IP68 with the “6” meaning dust proof and the “8” meaning waterproof and submergible to depths over 1 meter.
Cameras and monitors with pigtails (hardwired cables that exit the equipment) rated IP68 are only as waterproof as the cable / connector and in most cases only meet IP68 when connected to the mating cable. While the rating may be true it is only as reliable as the rubber cable connecting it. Once that cable jacket is breached the camera or monitor can quickly fill with water. INTEC's IP68 rated cameras, controllers, and displays do not use hardwired pigtails. Our connectors are sealed and secured to the units eliminating this potential weak link. While this type of construction costs more it is the only way to insure continual waterproof performance.
The following chart displays the IP rating system and what determines the IP Rating:
There is an additional rating of IP69K which relates to high pressure, high temperature wash down applications. To achieve this, the equipment must be able to withstand high pressure steam cleaning. The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, garbage trucks, cement mixers, etc.).
To pass the test our products must be able to withstand, without damage, high pressure by a spray nozzle that is fed with 80°C (176° F) water at 80 - 100 bar (1160 – 1450 psi) and a flow rate of 14–16 L/min (3.7 – 4.2 gal/min). The nozzle is held 10–15 cm (4 – 6 in) from the tested device at angles of 0°, 30°, 60° and 90° for 30 seconds each. The product sits on a turntable that rotates once every 12 seconds (5 rpm).
