Outdoor cable junction box

The BONAEVER 2-way 3-pin M20 junction box provides a certified connection point for joining or extending power cables in exterior environments. Each pack contains five units rated for voltages below 450 V and currents below 24 A, making them suitable for outdoor lighting circuits and general external wiring. The IP68 rating confirms protection against dust ingress and continuous immersion up to 3.5 m depth.

Cable diameter range 5 to 12 mm

Three interchangeable silicone rings accommodate cables from 5 mm to 12 mm outer diameter, ensuring a watertight seal for the specific conductors on site. Selecting the correct ring size is the single specification that determines whether the connector will maintain its IP68 integrity. An undersized or oversized ring will compromise the moisture and dust barrier.

Sustained immersion and UV exposure

The built-in rubber ring and clamping nut maintain the IP68 seal during prolonged submersion and resist UV degradation in permanent outdoor installations. Under continuous electrical load up to the rated 24 A the connector body remains stable without the overheating risk that can appear in short-term test conditions. The enclosure is not intended for permanent immersion deeper than 3.5 m or for voltages exceeding 450 V.
