3M PELTOR ATEX Heavy Duty Headset with Helmet Attachment
Working in extreme, high-noise environments requires communication gear that you can trust implicitly. The 3M PELTOR ATEX Heavy Duty Headset (MT72H540P3E-50) is engineered specifically for these demanding conditions, offering an optimal acoustic design that provides ample space for your ears while sealing out dangerous noise levels. Whether you are operating in oil and gas, manufacturing, or other hazardous sectors, this headset ensures your team stays connected and protected throughout long shifts.
Why choose this ATEX-certified headset for your team?
Safety and comfort are paramount when working in explosive or extreme environments. This headset is fully ATEX-certified (IECEx class ib IIC T4) for intrinsic safety. Beyond its rugged build, it features foam and fluid-filled cushions that provide an excellent noise seal while remaining comfortable during extended wear. The extra-high attenuating twin cup technology delivers an impressive 31dB of noise reduction, protecting your hearing while allowing clear audio reception through both ears.
How does the microphone perform in loud environments?
Communication is only effective if you can be heard clearly. That is why this headset is equipped with an easily adjustable, dynamic noise-cancelling boom microphone (230 ohm). It filters out heavy background industrial noise, ensuring your voice is transmitted crisply and clearly to your team.
How do I connect this headset to my two-way radio?
This headset utilizes a J11 connection type and requires a compatible ATEX flex lead PTT (Push-To-Talk) adapter to connect to your radio. For instance, if you are using a Motorola DP4000 ATEX radio, you will need to pair it with the appropriate PTT cable, such as the PMLN6803A or PMLN6368A. If you are looking for alternative connection options for standard radios, you might consider the 3M Peltor FLX2 Cable for MOTOTRBO DP4000 Series or the 3M Peltor FLX2 Cable for Motorola DP1400 / GP300 for non-ATEX setups.
Are there other headset styles available?
If you require different configurations for your fleet, we also offer the 3M Peltor CH-3 FLX2 Headset with Bluetooth Headband for wireless connectivity, or the 3M Peltor CH-3 FLX2 Headset with Built-in PTT Helmet Attachment for an all-in-one helmet-mounted solution.
