Key Features
IP57 Submersible
Tested underwater at 3 ft (1 metre) for 30 minutes — the PMMN4029A keeps working through rain, spray, and washdown.
Intrinsically Safe
Rated intrinsically safe for use in hazardous-location environments where a standard microphone isn't suitable.
Windporting Audio
Windporting reduces background noise from high winds and severe weather, so callers come through clearly. Audio passes through the speaker grill even when the mic port is blocked by water.
Built to Last
A 6 ft coil cord, swivel clip, and quick disconnect latch with PTT button make the PMMN4029A easy to wear, deploy, and detach on the job.
Compatible Radios
The Motorola PMMN4029A is designed for Motorola portable two-way radios, including the CP185, CP200d, Mag One series, and Motorola R2 handsets. Because hazardous-location and submersible accessories must be matched correctly to your exact radio model, confirm fitment before you buy — our Canadian radio experts can verify compatibility for your fleet.
