RS PRO Electret Condenser Microphone 18kHz, Omni Directional, 1kΩ, 3.5mm Mono Plug, 242-8905

RS PRO introduces the 242-8905 Electret Condenser Microphone, engineered for high-fidelity audio applications where precise and dependable sound capture is important. This compact, lightweight microphone features a robust electret condenser element offering exceptional sensitivity and an omni directional polar pattern, making it suitable for capturing voices and ambient sounds from any direction.

Designed for versatility, the 18kHz maximum frequency response and 30Hz minimum frequency response ensure excellent performance across speech and general audio tasks. With a 1kΩ output impedance, this microphone integrates seamlessly with most audio mixers, amplifiers, and portable devices, supporting both consumer and professional installations.

The device's compact design, at just 16mm in length and 8mm in diameter, makes it ideal for discreet mounting in clothing as a lavalier or in equipment setups where space is limited. A built-in amplifier and a cable with a 3.5mm mono plug simplify connection and minimize external interference, guaranteeing reliable operation when mobility is required.

Operating from a low 1.5V supply - commonly supported by button cell or AA batteries - the microphone is both energy efficient and easy to deploy in locations without fixed power supplies. Its sturdy construction supports daily use in settings such as public speaking events, conferences, lecture halls, portable field recorders, and lightweight AV setups.

High-performance electret condenser element for clear, natural sound reproduction. Omni directional pickup pattern for ambient sound and voice gathering in all directions. Wide bandwidth response (30Hz - 18kHz) for accurate frequency capture.

Low-noise output with -65dB sensitivity, engineered for professional results. Compact physical dimensions allow easy integration into microphones, wearable equipment, or embedded systems. 1kΩ impedance supporting a wide range of electronics, mixers, and recorders.

Pre-wired 3.5mm mono plug for convenient connection without soldering or modification. Lightweight - only 56.5g - for comfortable wear or unobtrusive system use.

Common applications include audio conferencing, mobile recording, educational lectures, PA systems, and integration in embedded projects. The RS PRO 242-8905 is a versatile fit for industrial, laboratory, commercial, and portable audio engineering needs.
