IP rating, sometimes referred to as International Protection rating, or Ingress Protection rating classifies the degree of protection provided by the drive enclosure against both solid objects and liquids.
The IP code, defined by International standard IEC 60529, generally consists of two digits that classify the level of protection provided in each case.
Optidrive enclosures are available in three IP ratings (dependent of the model range and specifications required). Consult the Stock drives catalogue for further information on available ranges. A summary of Optidrive IP ratings are given below.
IP20 enclosures provide some protection from accidental contact from hands / fingers and no protection against the ingress of water or other liquids into the drive enclosure. They are designed to be used where the drive is to be fitted within a suitably rated (higher IP) enclosure.
IP55 enclosures protect against ingress of dust to the point of preventing ingress of anything potentially harmful to the internal workings of the drive. The Optidrive IP55 is protected against exposure to low pressure water jets from any direction.
IP66 enclosures is rated as completely dust tight and protected against exposure to powerful water jets from any direction.
The level of IP protection you will require is dependent on your application and the conditions the Optidrives will be exposed to, and by any local regulations that are applicable to your application. Generally, if unsure, then always seek advice and elect to go with the higher IP rating.
