IP (Ingress Protection) Rating System

Background

Cursor Controls Ltd classifies the sealing capability of a trackball device using the ingress protection rating system detailed in the international standard IEC 60529.

The IP (Ingress Protection) rating system is used to indicate the degree of protection that an enclosure provides against the ingress of dust and liquids.

Trackballs are typically installed into a variety of user interface systems, many of which are required to meet a specified level of protection against liquids and dust. As such, it is essential that the trackball is also capable of protecting the system from exposure to the same environmental conditions. Within the Cursor Controls Ltd trackball range there are a number of trackball solutions providing various IP rating levels so it is important that the correct trackball is specified for the intended application. If the console is rated to IP65 then a trackball capable of meeting the IP65 test criteria (or above) will also be required.

The remainder of this application note details the IP code in more detail and provides information on the various IP rated trackballs available in the Cursor Controls Ltd range.

 

Summary of the IP code

A product’s IP rating is comprised of two numbers (e.g. IP68). The first number indicates a trackballs resistance to solid particle ingress while the second number indicates its resistance to the ingress of liquids.

A product that is rated IP68 for instance, provides greater resistance to liquid ingress than would a product rated IP65, while a product rated IP62 provides greater protection against ingress of solid particles than would a product rated IP32.

While other rating systems exist for ingress protection, our trackball products are rated using the IP rating system as this provides the clearest indication of product performance while allowing easy comparison with other devices.

All Cursor Controls Ltd IP rated products have been tested to ensure that their rating accurately reflects their performance in the field.

Please note that the IP rating is only applicable when the trackball is fitted into a panel with an equivalent (or better) sealing rating.

The IP Rating Guide below describes the IP rating system in more detail and illustrates the testing processes that the trackball products are subjected to before an IP rating is applied. This guide may be useful when specifying a trackball product for your unique application.
