Harsh environment speaker featuring extended frequency range

The speaker reproduces voice in the frequency response range of 450HZ to 20kHZ, and is tested to MIL-STD-810, method 509.1 (salt fog). The PZ-94 loudspeaker system features a high-strength phenolic cone to provide resistance to humidity, external shock, and vibration, while the low dynamic mass of its drive mechanism enhances transient response.

As a piezo ceramic device does not generate an electromagnetic field, OEMs are further ensured their products meet all applicable EMC requirements and regulations.

Well suited for use in MRI suites and Department of Defence (DoD) applications, the speaker’s robust design, small form factor and ability to reliably perform in harsh environments makes the component equally appropriate in a variety of medical devices, transportation modes, portable, and industrial products. It is also commonly specified in outdoor, car audio, instrumentation, portable electronics, public address, and paging applications. Furthermore, the PZ-94 is applicable for producing ultrasound in sonar systems.

In addition to featuring an extended frequency response range and tested to water resistance of coatings under a condition of 100% relative humidity, the ruggedised PZ-94 offers a nominal power handling capacity of 50W (EIA RS426) (8Ω system reference). It has an average sensitivity rating of 82dB at 1W/1m, and typically appears as a 1.5µF capacitor. The speaker measures 94mm in diameter with an approximate thickness of 15mm, while weighing 33g.

Delivery is from stock to 16 weeks, depending on quantity.
