Understanding IP Ratings
IP (Ingress Protection) ratings classify how well a connector resists dust and water.
IP Rating | Meaning | Application |
---|---|---|
IP67 | Dustproof, immersion up to 1m | Outdoor use |
IP68 | Long-term submersion | Marine/underwater |
IP69K | High-pressure washdowns | Food & medical |
Key Factors When Choosing Connectors
1. Sealing Structure
Choose connectors with O-rings, gaskets, and molded designs. Noderconn’s NC-M series offers multi-layered sealing for extreme durability.
2. Material Durability
Use materials like nylon PA66, nickel-plated brass, or stainless steel based on your environment.
3. Locking Mechanism
Threaded, bayonet, and push-pull locks are available depending on whether vibration resistance or quick-connect is required.
