HugeRock S50EX 4.5" ATEX Rugged Android Smartphone

Give your hazardous-area teams a phone they can actually take onto the plant. The HugeRock S50EX is a pocket-sized, ATEX-certified rugged Android smartphone — small and light enough to carry all day, tough enough for the refinery, and intrinsically safe for Zone 1 and Zone 2.

Certified safe for explosive atmospheres

The HugeRock S50EX carries a genuine ATEX certification (II 2G Ex ib IIB T4 Gb), meaning it is intrinsically safe — engineered so it can never release enough energy to ignite flammable gas, vapour or dust. That lets your team carry a connected Android smartphone into Zone 1 and Zone 2 areas where an ordinary phone or tablet is simply not permitted, replacing paper, radios and trips back to a safe zone.

Where the HugeRock S50EX earns its place

Built to keep working

Sealed to IP66 against dust and water jets and drop-tested to MIL-STD-810G from 6 feet, the S50EX shrugs off the knocks of real industrial work. Its 4.5-inch 500-nit display stays readable in direct sun and responds to gloved or wet fingers, while the 5000 mAh intrinsically-safe battery is user-replaceable to keep a spare on charge for the next shift.
