Key Specifications
IP Rating Standards
For waterproof magnetic connectors, the most critical parameter is the IP (Ingress Protection) rating. IP67 means total dust ingress protection and water immersion up to 1 meter for 30 minutes. Higher ratings like IP68 or IP69K indicate resistance to continuous immersion or high-pressure water jets.
Current and Data Capacity
Connectors must handle the intended load: consumer device charging often requires up to 5A, while industrial tools may exceed this. Data transfer, USB 2.0/3.0, Ethernet, or specialized protocols, demands matching contact configuration and shielding.
Durability Requirements
Design life depends on cycle count: quality connectors offer 5,000–10,000+ mating cycles. Engineers must specify based on the device's usage profile, including repeated connect/disconnect cycles and exposure to environmental stress.
