Raltron Introduces Precision Piezo-Electric Elements for Medical and Audio Applications
Raltron has announced the expansion of its piezo-electric element portfolio, showcasing a broad range of high‑performance components engineered for demanding audio applications, with emphasis on medical devices, IoT, Fire & Safety, and consumer electronics applications.
Raltron’s piezo-electric elements are available in diameters from 9 mm up to 65 mm, giving engineers wide design flexibility from ultra-compact wearables to larger, high-output acoustic transducers. These elements support frequency ranges from below 2 kHz up to 9 kHz, enabling precise tuning for audio signalling, alarms, prompts, and feedback tones in critical devices.
Manufactured with brass, nickel, or stainless-steel substrates, and with or without the third-wire feedback loops, the line is customisable with lead wires and connectors allowing designers to balance acoustic performance, mechanical robustness, and cost based on each application.
With stable audio performance and tightly controlled capacitance (2,300 pF to 35,000 pF), Raltron’s piezo elements support efficient drive requirements and consistent SPL output. This enables reliable audio signalling in compact, power-sensitive designs.
