| 0 | Zero Protection | No protection | 0 |
| 1 | Protection against solid objects larger than 50mm | Protection against vertically falling drops of water | 1 |
| 2 | Protection against solid objects larger than 12mm | Protection against direct sprays up to 15° from the vertical | 2 |
| 3 | Protection against solid objects larger than 2.5mm | Protection against direct sprays up to 60° from the vertical | 3 |
| 4 | Protection against solid objects larger than 1mm | Protection against sprays from all directions with limited ingress allowed | 4 |
| 5 | Limited protection against dust with no harmful deposits | Protection against low-pressure water jets from all directions with limited ingress allowed | 5 |
| 6 | Fully protected against dust | Protection against strong water jets (e.g., for use on ship decks) with limited ingress allowed | 6 |
![]() | Protection against water jets with higher pressure | 6k | |
| Protection against the effects of temporary immersion between 15cm and 1m for up to 30 minutes | 7 | ||

Waterproof Cable Assembly Products
JinHai provides comprehensive services from design to production, safeguarding diverse custom cable applications in commercial settings.

Waterproof D-Sub Rectangular Male Cable Assembly
This type of cable assembly features a multi-seal design. In addition to sealing at the connector interface plane (sealing ring), it employs compression-type or potting-type sealed gland heads at the cable exit points. The assembly also incorporates sealing treatment at the connector housing joints. This cable assembly is the preferred choice for aviation, marine, and heavy-duty outdoor equipment.

Waterproof M-Type Cable Assembly
Our waterproof M-type cable assemblies feature O-ring and front-seal designs to further enhance connector water resistance. These assemblies ensure stable connections between devices and networks, along with reliable signal transmission.

Waterproof (IP68) RF Cable Assembly
These waterproof coaxial connectors utilize a combination of O-rings and front seals to achieve IP67 and IP68 protection ratings, effectively preventing the ingress of moisture and fine particulate matter.
