PMMN4029 - IP57 RSM with Windporting

Communicate clearly in difficult weather with this Remote Speaker Microphone featuring Windporting technology. Windporting eliminates the whining and howling sounds of wind blowing across your remote speaker microphone while preventing water from clogging the microphone, resulting in clearer transmissions.

Built to survive, this RSM is approved to IP57 meaning it can withstand immersion for at least 30 minutes and dust won’t affect the operation no matter what.

Featuring intrinsic safety approvals to FM regulations, this RSM can be used in hazardous environments.
