ATEX Radios & Intrinsically Safe Two-Way Radios
Last updated: June 2026
An ATEX headset needs a radio to connect to. Here are the main intrinsically safe two-way radios on the market, how they compare, and which headsets work with each one.
Why You Can't Use a Standard Radio in a Hazardous Area
Standard two-way radios contain components that can generate sparks during normal operation — pressing the PTT button, inserting batteries, or even static discharge from the antenna. In an explosive atmosphere (flammable gas, vapor, or dust), any of these could trigger an ignition.
ATEX-certified radios have energy-limited circuits, sealed battery compartments, and anti-static housings. They are tested and certified by notified bodies to EN 60079-11 (intrinsic safety) and carry the distinctive Ex marking.

Radio + Headset Compatibility
Not every headset works with every radio. Compatibility depends on the connector type. Here's the pairing matrix:
| Headset | Motorola | Hytera | Kenwood | Tait | ecom PMR |
|---|---|---|---|---|---|
| Sensear SM1P-Ex | |||||
| Sensear SM1B-Ex | |||||
| ecom Ex-TRA 30 | |||||
| 3M Peltor LiteCom PRO III Ex | Built-in radio — no external radio needed | ||||
Sensear headsets use interchangeable cable adapters for different radio brands. The ecom Ex-TRA 30 requires specific cable variants per radio model. Always verify the exact part number with your supplier.
