Titanium Piezo Ultrasonic Transducer 70 Khz For Wire Embedding of Smart Cards

Specifications:

Description:

The 70 khz ultrasonic transducer is applied to embedding the coil wires to the smart card, or RFID card, and other small samples welding applications. Altrasonic R&D department design the small welding horn to weld, embed, or inlay, many kinds of small parts with different type shapes. 

The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.

Competitive Advantage:

1. Titanium welding horn (To enlarge the service life )

2. Once assembled, the transducers are aged before testing and final assembly. The properties of piezoelectric materials can change with time and pressure, so a bit of time on the shelf prior to testing will identify nonconforming material.

3. One by one testing to ensure that each transducer performance are excellent.

4. In good heat resistance, can be used in a wide range of temperature with long life and high reliability.
