Motorola MOTOTRBO R7Ex ATEX IIA 350–470 MHz FKP WiFi/Bluetooth/GNSS PZA402HEEX (MDH57SDN9RA3AN)

The Motorola MOTOTRBO R7Ex is an intrinsically safe digital two-way radio developed for use in explosive and high-risk environments such as chemical plants, refineries, energy facilities, and heavy industry. This UHF IIA 350–470 MHz Full Keypad (FKP) variant combines advanced voice communication, exceptional durability, and certified safety in accordance with ATEX, IECEx, and marine standards.

Built to deliver reliable communication in hazardous zones, the R7Ex sets a high standard for safety, performance, and operational efficiency.

Superior Audio Performance

AI-powered noise suppression, intelligent automatic volume control, and IMPRES™ technology ensure clear and consistent communication even in high ambient noise. Automatic feedback suppression reduces interference when multiple radios operate in close proximity.

Certified Safety for Hazardous Environments

The R7Ex is certified for gas (IIA), dust (IIIC), and mining (I M2) environments under ATEX and IECEx standards. Audible and visual alerts warn users if non-approved batteries are installed, enhancing operational safety and asset protection.

Engineered for Extreme Conditions

The device withstands water, dust, chemicals, and temperature extremes. With IP66 and IP68 protection, MIL-STD-810G/H compliance, and impact-resistant housing, the radio remains operational under demanding field conditions. Large, glove-friendly controls and a prominent emergency button support fast response in critical situations.

Advanced Digital Capabilities

Full Keypad (FKP) models include Bluetooth 5.2 and dual-band Wi-Fi (2.4/5 GHz, WPA3 compatible), enabling over-the-air programming and indoor location tracking via iBeacons.
All R7Ex models feature integrated GNSS supporting GPS, GLONASS, Galileo, and BeiDou for comprehensive personnel and asset tracking.
