IP SOLIDS RATING
Not rated for protection against contact or ingress (or no rating supplied)
Protection against solid objects larger than 50 mm (e.g. accidental contact with any large surface of the body, but not deliberate body contact).
Protection against solid objects larger than 12 mm (e.g. accidental finger contact).
Protection against solid objects larger than 2.5 mm (e.g. tools).
Protection against solid objects larger than 1 mm (e.g. small objects such as nails, screws, insects).
Dust protected: partial protection against dust and other particulates (permitted ingress will not compromise the performance of internal components).
Dust tight: full protection against dust and other particulates.
Solids Rating - 6 (dust tight)
Liquid Rating - 7 (1 meter/30min immersion)
IP LIQUIDS RATING
Not rated (or no rating supplied) for protection against ingress of this type.
Protection against vertically dripping water. No harmful effects when the item is upright.
Protection against vertically dripping water. No harmful effects when tilted up to 15° from normal position.
Protection against water sprayed directly at any angle up to 60° off vertical.
Protection against splashing water from any direction. No harmful effects when tested for at least 10 minutes with an oscillating spray (limited ingress permitted).
Protection against low-pressure jets. No harmful effects when water projected in jets from 6.3 mm nozzle, from any direction.
Protection against powerful water jets. No harmful effects when water projected in jets from 12.5 mm nozzle, from any direction.
Protection against full immersion at up to 1 meter depth for up to 30 minutes. Limited ingress permitted with no harmful effects.
Protection against immersion beyond 1 meter. Equipment is suitable for continuous immersion in water. The manufacturer may specify conditions.
IP rating codes are internationally recognized and follow a standardized scale defined in IEC 60529 and its national or regional equivalents such as ANSI 60529 in the US and EN 60529 in Europe. The code contains the IP or “Ingress Protection” prefix followed by two numbers. The first number describes resistance to ingress of solids such as dust or other small particles, while the second number expresses protection against liquids.
Example: IP67 connectors are built for use in tough environments. In the IP connector ratings, the 6 means that the connector can completely keep dust out, a characteristic critical to the assembly’s performance in a desert environment. The following 7 indicates that the connector is water resistant up to 1 meter deep for 30 minutes or less.
