i.safe MOBILE IS440.RG Rugged 5G Radio

What environments is the IS440.RG rugged 5G radio designed for?

The IS440.RG is built for demanding industrial settings where equipment must withstand vibration and the unpredictable handling that comes with field work. It performs well around production lines, maintenance areas, logistics operations, and processing facilities.

While many teams working near hazardous zones require reliable communication, this model is intended for non-Ex areas only and must not be used where combustible atmospheres are present. For operational teams who work adjacent to restricted areas, it integrates smoothly into broader workflows and complements certified devices used directly inside hazardous zones.

Does it support push-to-talk applications and LTE/5G networks?

Yes. The IS440.RG includes dedicated hardware controls—such as a channel selector, programmable side key, and an amplified loudspeaker—designed for PTT workflows. It has compatibility with leading push-to-talk platforms, including TASSTA. Actual PTT functionality depends on the communication software installed by the organization.

This rugged 5G radio uses modern LTE and 5G networks to deliver reliable connectivity across large facilities or dispersed worksites. The device is optimized for quick channel switching and dependable operation in noisy, high-movement environments. Although not certified for hazardous zones, the IS440.RG integrates smoothly into wider hazardous-area communication solutions by supporting PoC communication in the surrounding safe areas.

How does it differ from standard smartphones?

The IS440.RG is engineered for durability, not consumer convenience. It features a reinforced housing, tactile controls, and impact resistance that protects it during drops and exposure to dust or moisture. These capabilities separate it from consumer devices and make it valuable in safety-critical work.

Although some teams adopt an intrinsically safe smartphone alternative for restricted zones, this model is specifically intended for surrounding work areas where ruggedness and reliability matter most. Exloc Instruments supplies it for roles where mobile communication must continue despite harsh environmental conditions.

Is the device explosion-proof or intrinsically safe?

No. According to the operating manual, the IS440.RG must not be used in explosion-hazardous atmospheres. It is not an intrinsically safe device and should not be considered an ATEX-rated product. Instead, it operates as a high-performance radio for safe-area tasks that still require tough equipment.

Teams seeking an intrinsically safe communication device or a certified ATEX smartphone alternative should select a fully compliant model appropriate for their classified zone. The IS440.RG supports these workflows by delivering rugged connectivity in adjoining non-Ex environments, often as part of a hazardous-area communication solution that includes certified hardware for restricted spaces.

What accessories or headsets can be paired with the IS440.RG?

The radio supports a wide selection of i.safe MOBILE accessories—headsets, remote speaker microphones, carry systems, and charging solutions—allowing users to configure the device for their specific tasks. These accessories improve usability in high-noise areas, expand hands-free options, and help workers maintain clear communication during busy shifts.

Because the IS440.RG uses the same 8-pin ISM accessory interface found on many certified Ex devices, teams can use similar workflows across safe and hazardous zones even when switching between models. This compatibility gives organizations a smooth equipment setup that strengthens daily communication.

What kind of battery life and durability can users expect?

The IS440.RG features a replaceable 2400 mAh battery with a 4800 mAh high-capacity option to support long workdays. Swapping batteries keeps teams productive without returning to a charging station mid-shift.

Durability is further reinforced by its IP68 rating and compliance with MIL-STD-810H testing, making it resilient against water immersion and other punishing conditions common in the field. This rugged 5G radio continues to perform in environments where ordinary devices struggle, helping teams maintain consistent, dependable communication throughout the day.
