What is IP?• IP stands for Ingress Protection. • The IP rating tells you how

resistant a mechanical casing or electric enclosure is to dust particles and liquids entering the electronics of the device.

• An IP rating gives an idea of how vulnerable the product is to contamination and damage caused by solids and liquids getting into the unit.

• The SR500 has an IP rating of 67. The first digit signifies particles, and the second digit signifies liquids.
