Main Features of RM-W Series Multi-Purpose Circular Waterproof Connectors
The RM-W series features a threaded coupling type lock mechanism that provides reliable waterproof performance
Assembly type (straight plug / RM15W)
Assembly type (right-angle plug / RM15W)
1. Abundant variations
The RM-W series features a wide variety of plugs and receptacles, enabling you to find the ideal product for the given application.
Three types of plugs are available: straight type, straight low-profile type and right-angle type.
A single-unit, waterproof type receptacle is available in which the connector itself is waterproof.
The screw-fastening type is available either as a front mounting type or a back mounting type.
Available number of contacts: 2, 3, 4, 8, 10, 12, 15, 20, 40, 55. Two types of contact plating are available: gold plating and silver plating.
2. Waterproof structure
Meets IP68 standards for waterproof performance when mated. Also, the single unit waterproof receptacle features IP68-class waterproof performance.

Connector Usage Precautions
- 1. Make sure the power is off before mating or un-mating the connector.
- 2. Use connectors with socket (female) contacts at the power side of the circuit.
- 3. Make sure that the coupling is in the completely locked position (fully tightened state.)
- 4. Always use the correct plug / receptacle to assure water protection.
