Three Mallory PT-7A piezoelectric transducers (2.5 kHz) are included. The PT-7A device converts mechanical vibrations into an electrical signal and is used in audio pickups and vibration sensing applications where a compact piezo element with a 2.5 kHz response is required. These Mallory transducers are part of the PT-7A lineup and are suitable for tasks that demand reliable piezoelectric performance in a small form factor.
