Technical Specifications

The B6027AL30-L100DFS is a rugged 6mm waterproof omnidirectional electret microphone capsule designed for outdoor audio capture in embedded systems. With a sensitivity of -30dB and a signal-to-noise ratio of 74dB, it delivers clear and consistent sound performance across a 20Hz to 8000Hz frequency range, making it ideal for general environmental monitoring and voice pickup in outdoor conditions.

Engineered for durability, this capsule integrates waterproof mesh protection for reliable performance in wet or humid environments. The 100mm double-shielded twisted pair leads with pre-attached terminals provide strong EMI resistance and convenient integration with PCB assemblies. Common applications include security cameras, smart poles, outdoor kiosks, and other voice-enabled outdoor electronics.
