Elk Grove Village, Ill. Transducers USA has released its TRPB series of dual-sided bender, piezo ceramic audio transducers. These devices feature a unique ceramic process that deposits crystals on both sides of the metal bender. This allows the transducers to be used with higher voltage drives, thereby producing a higher dBA sound output, said the company.
The TRPB series allows for drive voltages in excess of 60 Vdc at 40 mA maximum, producing an output of over 100 dBA at a frequency of 2500±500 Hz. The TRPB-XXXX series units are offered in a black thermoplastic housing with a diameter of 45 mm x 13.5-mm deep. Mounting is via PC pins. Custom designs are available with or without feedback, special terminations and package configurations. Click the link for more information about the TRPB series.
The TRPB devices are priced at $.70 each in quantities of 1,000. Sample quantities are available from stock with lead times of four to six weeks for larger quantities.
