dual antimagnetic mechanisms to minimise the potential risk of explosion caused by
overheating and electronic sparks in highly hazardous environments with explosive gas

and combustible dust. Built with meticulous engineering and innovation, these devices

emphasise safety without compromising on performance, demonstrating Hytera’s
dedication to delivering top-of-line communications solutions tailored for industries in the

region and across the world.

PNC460U Rugged Explosion-proof Smartphone with Push-to-talk

The PNC460U, Hytera’s first UL913-certified ruggedized IS smartphone, is designed to

facilitate instant group communications, i.e. push-to-talk (PTT) calls, mobile office APPs
and data transmission in hazardous environments. It complies with explosion-proof

requirements for use in Class I, II, III, Division 1, Groups C-G and T4 and -20°C to 60°C
(-4°F to 140°F) areas. Sporting a 5-inch HD screen and Android 12 OS, the device comes

with a dedicated PTT key and seamlessly blends smartphone capabilities with PoC radio
functionalities. It works with specialised APPs and dispatch software to achieve versatile

PTT voice calls, video calls, and visualised dispatching.

PT890Ex and HP79XEx Intrinsically Safe Portable Radios

Bolstering Hytera’s Professional Mobile Radio (PMR) offerings are two new entries – the

PT890Ex and HP79XEx. The PT890Ex, a TETRA portable radio, and its counterpart, the
HP79XEx, a DMR variant, are both IECEx certified. Crafted with advanced explosion-

proof materials, the new radios are engineered to withstand intense temperatures ranging

from -25°C to 60°C (-13°F to 140°F) in hazardous environments without the risk of
triggering explosions. Additionally, PT890Ex and HP79XEx utilise innovative silicone

encapsulation technology to guard against threats like liquids and flammable dust from
intruding the circuits. The adoption of multiple circuit protection mechanisms further

enhances safety even with high audio output power of 2 watts.

“The PNC460U marks an important milestone for Hytera to bring push-to-talk

smartphones into the intrinsically safe arena. The crucial position of Dubai as one of the

most technologically advanced cities in the Middle East, as well as the region’s availability
