Motorola PMMN4067B
ATEX IMPRES Remote Speaker Microphone
Intrinsically Safe Audio Solution with Windporting for Hazardous Environments
The Motorola PMMN4067B is a high-performance, intrinsically safe remote speaker microphone designed for use in the world’s most demanding and volatile environments. Featuring full ATEX/IECEx and CSA certification, the Motorola PMMN4067B is engineered to operate safely in areas where flammable gases or combustible dust are present. By integrating Motorola’s proprietary IMPRES technology, this microphone automatically suppresses background noise and amplifies quiet transmissions, ensuring that mission-critical voice commands are heard clearly even in the presence of heavy industrial machinery or emergency sirens. The Motorola PMMN4067B is the updated version of the Motorola PMNN4067A, and Motorola PMMN4067.
Equipped with advanced Windporting technology, the Motorola PMMN4067B excels in outdoor operations by eliminating the howling and whining sounds caused by high winds blowing across the microphone element. This specialized design also prevents water from clogging the microphone, ensuring consistent performance in torrential rain. With a dedicated volume control toggle and a highly visible orange emergency button, the Motorola PMMN4067B provides operators with instant access to critical radio functions while wearing heavy protective gloves, making it an indispensable tool for oil and gas, chemical processing, and fire rescue teams.
