The Ingress Protection (IP) rating of a CW (Cable Wire) cable gland is a measure of its effectiveness in protecting against the intrusion of solids and liquids. The IP rating is typically expressed as "IP" followed by two digits. The first digit represents protection against solids, and the second digit represents protection against liquids. The higher the digit, the greater the level of protection. However, it's important to note that not all cable glands have an IP rating, and the rating can vary depending on the specific model and manufacturer.
For example, a common type of cable gland used in industrial applications is the CW cable gland. If it has an IP rating, it might be expressed as "IP68." Here's a breakdown of the IP68 rating:
IP6x (Solids Protection): The "6" in IP68 indicates that the cable gland is dust-tight. It provides complete protection against the ingress of dust or other solid particles.
IPx8 (Liquids Protection): The "8" in IP68 indicates that the cable gland is protected against the effects of immersion in water beyond 1 meter. In practical terms, it suggests that the cable gland can be submerged in water deeper than 1 meter for a specified period without allowing water to penetrate.
