This Peltor adapter is specifically designed for connecting your Peltor equipment to the Motorola DP4000 series of ATEX Radios. Namely the DP4401Ex and the DP4801Ex
The adapter has a large tacticle Push to Talk button or PTT meaning you can easily transmit and talk without having to remove big gloves. Its large design means it can also be squeezed with an arm if you are carrying out a task or have dirty/contaminated gloves.
A large coiled cable links from the adapter to your radio meaning you have total flexibility when working, no constrains by small tight cables.
