What Does IP67 Rating Mean?

What does the IP stand for?

IP stands for “Ingress Protection” and is the International Protection Marking per IEC standard 60529. The most common use of an IP rating is how protected a product – such as a night vision optic – is from a solid or liquid entering the product.

What do the numbers mean?

Following the letters “IP” are typically 2 digits which indicate the level of protection of the product. The first digit indicates the level of protection a product has from a solid – i.e. a finger, screwdriver, or even dust. The second digit indicates the level of protection a product has from liquid intrusion in certain volumes, pressures, or temperature.

For example, a Sytong HT-60 that is IP67 rated will remain protected and fully operational in most industrial applications, including those where the optic is exposed to water spray, rain, debris, etc. The “6” indicates the optic is completely protected against solid objects from entering the sensor, including dust, while the “7” indicates the sensor can be completely submerged in 1 meter of water for up to 30 minutes before the moisture penetrates the housing.

IP Ratings Guide

4: Protected against a solid object greater than 1mm.
5: Dust protected. Limited ingress of dust permitted.
6: Dust tight. No ingress of dust.
X: Not rated.

Liquids
1: Protected against vertically falling drops of water.
2: Protected against vertically falling drops of water with enclosure tilted up to 15 degrees from the vertical.
3: Protected against sprays of water up to 60 degrees from the vertical. Limited ingress permitted for three minutes
4: Protected against water splashed from all directions.
5: Protected against jets of water.
6: Water from heavy seas or water projected in powerful jets shall not enter the enclosure in harmful quantities.
7: Protection against the effects of immersion in water between 1cm and 1 m for 30 minutes
