Product Details:
The STAR MICRONICS QMX05 is a piezoelectric sound transducer designed for audible signaling applications. This RoHS-compliant component utilizes a mechanically resonant diaphragm driven by a piezoelectric element to generate sound pressure. The QMX05 typically operates within a frequency range of 2.0 kHz to 4.0 kHz, with optimal performance characteristics dependent on the specific driving circuit and enclosure design. Electrical characteristics include a specified impedance, typically in the hundreds of ohms, and a low current consumption, generally in the milliampere range, making it suitable for battery-powered devices. The transducer’s sound pressure level (SPL) output is influenced by the applied voltage and frequency, and must be carefully considered during system integration to meet desired acoustic output requirements. The QMX05 is commonly used in applications such as alarms, buzzers, and audible indicators in electronic devices.
