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.

3. Flexible cable arrangement

With the assembly type right-angle plug, the cable can be pulled out in any direction (360° range.)

Connector Usage Precautions

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