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. SHUNKONN’s MC16/MC12 series offers multi-layered sealing for extreme durability.

2. Material Durability

Use materials like nylon PA9T, Copper C3604, copper gold-plated G/F on your environment.

3. Locking Mechanism

Threaded, bayonet, and push-pull locks are available depending on whether vibration resistance or quick-connect is required.
