PREMO Group
Premo enlarges its telecoil family with the TC0502 series, a high reliability and sensitivity coil for application in hearing aids developed according to the highest quality standards (ISO/TS16949:02,ISO9001:2000).
The telecoil is wound with thin copper wires up to 0.012mm diameter and inductance values between 40 and 270mH. The TC0502, achieves a high sensitivity to magnetic field in 1kHz (operation frequency in this kind of devices).The ferrite core material provide a stable performance in a wide range of temperature (-10ºC to +40ºC).
Its Surface Mounting Device (SMD) configuration allows an easy integration in an automatized printed circuit board assembly process, avoiding handling of the piece that could damage winding wire of the piece. That's make this piece different regarding main existing telecoils, commonly with a "thru-hole" configuration (that requires an additional wave soldering process).
These components, included in most of existing hearing aid devices, work as magnetic field sensor, turning the magnetic field into electric voltage as a standard microphone does with the acoustic energy. This allows the hearing handicapped people to receive the signal from a magnetic inductive loop located in public buildings and transports. Additionally these components improve binaural communication (stereo sounds) and phone, television and radio hearing.
Besides, the inclusion of this kind of coil in compatible hearing aid with mobile phones, the user can change the phone coil in manual or automatic way, to create a magnetic field as intensive as to transmit the signal to hearing aid.
The excellent quality and high reliability of this telecoil has been evaluated positively for the main hearing aid manufacturers. This kind of coil is used in most hearing aids worldwide. The TC0502 family is offered with electrics characters "custom" according to customers need.
