i.safe ATEX phone or smartphone: how to choose?

The i.safe MOBILE IS120 series is a classic ATEX push-button phone designed for simplicity and long battery life: calls, SMS, and a programmable PTT button to connect to your radio solution. It is the most robust and straightforward choice for daily voice communication in hazardous areas.
The IS540 and IS880 smartphones run on Android and offer a touchscreen, allowing for the installation of business applications: geolocation, LWP/man-down, camera, barcode scanner. They are suitable for teams that need more than just voice: traceability, field data reporting, or integration with your digital tools.

Zone 1/21 or zone 2/22: which ATEX certification should you choose?

Zone 1/21 corresponds to a location where an explosive atmosphere (gas for zone 1, combustible dust for zone 21) is likely to form occasionally during normal operation: this is the highest risk level in a classified zone. Zone 2/22 corresponds to a lower probability of an explosive atmosphere occurring, and for a shorter duration.
A terminal certified for zone 1/21 (IS120.1, IS540.1) can be used in both zone 1/21 and zone 2/22. Conversely, a device certified only for zone 2/22 (IS120.2, IS540.2, IS880.2) is not authorized in zone 1/21. If you are unsure about your site's classification, contact us: we will guide you to the right model.

4G or 5G: which network should you choose for your ATEX terminal?

The IS120.1, IS120.2, and IS880.2 models operate on 4G, which is more than enough for calls, SMS, and the majority of business applications used in the field. The IS540.1 and IS540.2 models include 5G, which is useful for sites that already have compatible infrastructure or require high data rates (video, large file transfers, real-time applications).
For standard voice and PTT use, 4G meets the vast majority of needs. 5G becomes relevant as soon as the terminal needs to transmit large amounts of data continuously.

Robustness and sealing: terminals designed for industry

i.safe MOBILE smartphones are IP68 certified (total dust protection and immersion resistance) and designed to withstand shocks according to the MIL-STD-810H military standard. Combined with ATEX/IECEx certification, this robustness makes them reliable terminals for daily use in demanding industrial, maritime, or logistics environments.

Frequently Asked Questions

What is the difference between the i.safe MOBILE IS120.1 and the IS540.1?

The IS120.1 is a classic ATEX phone (physical keys, calls and SMS, PTT compatible) certified for zone 1/21, designed for robustness and battery life. The IS540.1 is a 5G Android touchscreen smartphone, also certified for zone 1/21, which allows for the use of business applications (LWP, geolocation, camera) in addition to calls.

What is the difference between zone 1/21 and zone 2/22 in ATEX?

Zone 1/21 corresponds to a location where an explosive atmosphere (gas for zone 1, dust for zone 21) is likely to form occasionally during normal operation. Zone 2/22 corresponds to a location where this probability is lower and of shorter duration. A zone 1/21 certified terminal can be used in both zones, but not the other way around.

Should you choose a 4G or 5G terminal?

The IS120.1, IS120.2, and IS880.2 models operate on 4G, which is sufficient for calls, SMS, and most business applications. The IS540.1 and IS540.2 models include 5G, which is useful for sites that require high data rates or already have compatible infrastructure.

Are i.safe MOBILE phones shock and water resistant?

Yes, i.safe MOBILE smartphones are IP68 certified (water and dust resistant) and designed to withstand shocks according to the MIL-STD-810H military standard, for use in demanding industrial environments.

Are i.safe MOBILE terminals compatible with an LWP solution?

Yes, i.safe MOBILE smartphones are compatible with Lone Worker Protection (LWP/man-down) applications, and the IS120 phone features a programmable PTT button for use with your radio solution. Contact TRPS for a configuration tailored to your business.
