MOTOTRBO R7Ex ATEX-Certified Portable Two-Way Radio

Portable two-way radio is a vital form of mission critical communication in industries where hazardous environments are present. Electrical devices can trigger accidental fire or explosion in environments where airborne gasses, chemicals, and dust are present. A stray spark or static electricity buildup in a device creates a potential for ignition and accidental combustion. Designers were challenged to develop an intrinsically safe communication solution able to meet the varied and stringent (ATEX) certifications required for a variety of industries. They were also tasked to incorporate safety functionality such as lone worker alert, fallen worker alert, and location monitoring.

The R7Ex solution resulted from extensive research and observation in target industries. It was designed to meet requirements from multiple certification and safety compliance organizations throughout the world. The distinctive blue color establishes an internationally recognized visual differentiation from ordinary non certified devices. R7Ex also meets mil std specifications for ruggedness in harsh environments. Research led to development of features such as glove friendly knobs and buttons and intuitive tactile controls. AI trained noise suppression enhances audio clarity in high noise use environments. A call recording feature enables users to store and review previous transmissions for added understanding.

The stringent certification process required for communication equipment used in hazardous environments has made the adoption of many modern radio features a difficult technical challenge. The R7Ex solution brings AI enhanced audio, remote programming functionality, text messaging, fall alert, bluetooth/wifi, and rugged tactile ergonomics to a segment that has not previously had the benefits of these improvements. This serves to improve worker safety and productivity in vital industries where harsh working conditions, including the potential for fire and explosion, are prevalent.

With loud, clear audio plus a range of advanced features, R7Ex helps workers hear calls and share messages more clearly, boosting performance, increasing productivity and reducing downtime.
