Features
Capturing reliable audio in high-risk industrial environments requires equipment built to handle the pressure. The 2MEX-MIC2 Explosion-Proof Sound Pickup Microphone by 2M Technology delivers exceptional acoustic performance while maintaining strict safety standards in volatile Zone 1 gas atmospheres. Designed for life, this heavy-duty unit ensures your security and monitoring teams never miss a critical sound, no matter how harsh the surroundings are.
Advanced Audio and Noise Reduction Technology
Industrial environments are notoriously loud. To combat heavy background interference, this Explosion-Proof Sound Pickup Microphone features integrated multi-level dynamic noise reduction technology. This specialized engineering ensures that the omnidirectional microphone delivers consistently clear audio with minimal background noise.
Furthermore, the unit is equipped with an Automatic Gain Control (AGC) circuit, lightning protection, and reverse-polarity power protection. These built-in safeguards keep the internal electronics running smoothly and securely, avoiding power-related failures during critical monitoring periods.
Engineered for Gas Safety and Extreme Durability
Safety compliance is the top priority in hazardous workspaces. This Explosion-Proof Sound Pickup Microphone carries the rigorous Ex d IIC T6 Gb certification mark. This means the microphone is strictly tested and proven safe for environments exposed to volatile gas and vapors, helping your facility maintain compliance with OSHA hazardous location standards.
Beyond its explosion-proof capabilities, this device is designed for ultimate physical resilience. The housing is constructed from your choice of high-quality 304 or 316L stainless steel, offering superior durability and heavy-duty corrosion resistance. It also boasts a fully waterproof, IP66-rated construction so you can confidently deploy it in areas exposed to heavy weather or washdowns.
Wiring and Connection Details
Integrating the Explosion-Proof Sound Pickup Microphone into your existing network is straightforward. The connection utilizes a red cable for the 12VDC positive pole, a black cable for the ground, and a white cable for the audio positive pole. For transmission, the unit supports a 3-core 0.5mm RVVP cable, an ordinary 4-core telephone cable, or a Category 5 network twisted pair cable.
