Product Description
Parameters

Soft PZT

High sensitivity or "soft" ceramics feature high sensitivity and permittivity, but under high drive conditions are susceptible to self heating beyond their operating temperature range . These materials are used in various pick-ups and sensors, low-power motor-type transducers, receivers, and low power generators.

The ideal application of soft piezo materials is sensing needs.

Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
