Waterproof Connectors - Where are they used and how are they rated?


Where are they used?

Dust and moisture are the two most common contaminants that enter through exposed data ports, damaging or destroying electronic equipment. Fortunately, specially sealed cables and connectors are available to protect these ports from dust and moisture. Applications for these connectors are numerous and include automotive, communication, industrial and medical instruments. L-com offers a number of protected interface types including:

Fiber Optic
D-Subminiature
RJ45
USB
Fiber Optic
D-Sub
RJ45
USB

How are they rated?
The most popular system to rate the environmental protection of a particular connector is the Ingress Protection rating (commonly known as IP rating).
The IP rating is a number ranging from 1 to 3 digits.
  • The first digit rates protection against ingress of solid objects
  • The second digit rates protection against ingress of liquids
  • The third digit rates protection against impact damage
Note: Many products, including L-com products, are not rated for impact damage. Larger value digits indicate greater protection against that substance/force. Please see the chart below for details of the first two digit ratings:
