Intrinsically Safe Digital Portable Two-way Radio

Improved PCB Circuit Layout & EMC Shielding
To achieve such a high safety standard, Hytera PD79X Ex adopts optimized distributed line design on PCB, minimizing the odds of circuit fault. All the key components on the PCB are covered with shield, and the space between lines, between components, between component and shield are properly spaced , which translates to better EMC performance and less internal interference.

Innovative Silicone Encapsulating
Silicone encapsulant technology prevents the internal circuits from interface with air and liquid which effectively stops the intrusion of liquid, dust and harmful gas. The silicone encapsulating process is delicate and complicated. As a result, every single PD79X Ex radio spends eight hours in the manufacture line.

Innovative Electrostatic Free Design
Hytera applies patent on electrostatic free design and dual-material molding technology in this intrinsically safe portable. The static dispersive material (blue) minimizes static accumulation on the surface, thus reducing the probability of static discharge on the radio. Meanwhile the robust material (black) maximizes the ruggedness of the enclosure.

IP67 (non-explosion-proof)
The Ingress Protection reaches IP67 (6: Totally protected against dust; 7: Protected against the effects of immersion up to 1m for 30 minutes). It’s the highest IP level for land-based wireless radio application.

Patented Battery Latch
To disengage the battery from Hytera digital portables, the lock and bolt of the latch need to be moved along two different axes. Such a patented design ensures no disengagement of the battery pack from the main radio in case of dropping that might cause spark
