Features
Designed for safe and reliable audio monitoring in hazardous environments, the 2MEX04-MIC explosion-proof microphone combines rugged construction with high-performance sound capture. Built with corrosion-resistant Stainless Steel 304 and certified to Ex db IIC T6 Gb and Ex tb IIIC T80°C Db standards, it ensures maximum safety in both explosive gas (Zone 1) and combustible dust (Zone 21) areas. Its IP66 ingress protection rating defends against dust ingress and powerful water jets, making it suitable for tough industrial settings.
Operating in extreme temperatures from -40°C to +60°C, this microphone maintains consistent performance in harsh outdoor and indoor environments. With a frequency response of 20 Hz to 20 KHz and a sensitivity of -42 dB, it captures clear, accurate audio within a 1 m² monitoring range, making it ideal for local sound detection in hazardous zones. The output impedance of 600Ω nonequilibrium ensures compatibility with industrial audio systems.
This microphone supports AC 100–240 V or DC 12 V power inputs, consuming less than 100 mA of working current for energy efficiency. Installation is simplified with a single M16 x 1.25 cable thread hole, designed for secure and standardized connections to explosion-proof equipment with audio interfaces. Weighing 1.8 kg (3.97 lb), it offers a balance of durability and ease of installation.
Ideal for use in oil refineries, chemical plants, offshore platforms, and grain processing facilities, this microphone provides safe and effective audio monitoring where explosive atmospheres are a constant risk.
