Waterproof Junction Box

The BONAEVER M16 junction box provides IP68 rated protection for outdoor electrical connections. It includes both 2-pin and 3-pin threaded connectors with rubber rings to suit cables from 3.5mm to 10mm diameter. Rated for 17.5A and 450V, it handles live, neutral and earth conductors in a compact PA66 nylon housing measuring 2.55 by 0.78 by 0.78 inches.

Thermal And Safety Ratings

The enclosure meets IP68 after testing at four metres depth for 120 hours and carries a UL94 V-2 flame retardant rating. It operates continuously from minus 40°C to 105°C and withstands a 2500V pressure test. Certifications include CQC, SAA, UL, TUV, RoHS and CE for comprehensive safety compliance in harsh environments.

Sustained Outdoor Performance

Designed for permanent installation, the box maintains its seal and electrical integrity across the full temperature range without degradation. Mounting tabs and sturdy closing fixtures keep connections secure on RV hook-ups, pool equipment, lighting circuits and motorcycle wiring where continuous exposure to water, dust and vibration occurs.

Questions about this item

How do I install the M16 junction box and which rubber ring do I use for a 6 mm cable?

Thread the cable through the M16 gland, select the 3.5-7 mm rubber ring for a 6 mm cable, insert wires into the 2-pin or 3-pin terminals (live, neutral, earth), tighten the terminal screws with a screwdriver, then secure the gland nut to compress the seal.

What parts will need replacement after long-term outdoor exposure?

The PA66 nylon housing is rated for -40 °C to 105 °C and IP68 at 4 metres for 120 hours; only the rubber sealing rings may degrade over years and can be swapped with the spare 3.5-7 mm or 7-10 mm rings supplied.

At what current does the connector reach its thermal limit during continuous use?

The connector is rated for ≤ 17.5 A at ≤ 450 V; sustained loads above 17.5 A will exceed the certified thermal limit of the terminals and the UL94 V-2 flame-retardant housing.
