The Sonoff IP66 Waterproof Casing provides a secure, weather-resistant environment for your smart switches, protecting them from dust and powerful water jets. Built from white ABS V0 fire-retardant plastic, the shell is designed to withstand shocks, wear, and UV exposure, making it suitable for outdoor installations where durability is essential. Its compact dimensions of 132.2 x 68.7 x 50.1 mm and light weight of 145 g ensure it doesn't take up much space while remaining sturdy. A transparent front panel allows you to check status LEDs or read device labels without opening the enclosure. To maintain its seal, the kit includes two cable glands that accommodate wires with a diameter between 3 and 6.5 mm. This casing is specifically tailored for the PCBA versions of the SONOFF POW, DUAL, TH10, TH16, and G1, as well as the SONOFF Basic and RF models. The package comes complete with the casing, cover, and four mounting screws for a straightforward setup.
