There are as many terms used to describe waterproof connectors as there are reasons for needing one, such as water resistant, water repellent, and watertight. The best way to ensure you have the proper connector for your project is to find the IP rating associated with the connector you plan to use.
IP (Ingress Protection) rating is the most common system for evaluating how “waterproof” your connector is. IP rating is categorized by two digit numbers. The first digit represents the protection rating against solid foreign objects such as dusts. The second digit represents the protection against the ingress of liquids.
Mencom offers a wide selection of waterproof connectors from IP44 and IP68 connectors. Typical IP ratings for waterproof connectors in the manufacturing industry are IP67 and IP65. IP67 waterproof connectors provide complete protection against dust, and ingress of water when immersed in one meter of water for 30 minutes. IP65 waterproof connectors provide complete protection against dust, and protection of water jets from all directions.
