Telecoils

Sonion’s product portfolio also offers a wide variety of telecoils for hearing instruments.

The active telecoil (product name begins with TA) has an extra amplifier to boost output, shape frequency response and provide extra EMI protection. The Telecoil TA 20 models offer this extra amplifier.

The passive telecoil (product name begins with T) does not have the extra amplifier. These telecoils are designed by manipulating the core and the wire windings to offer different sensitivity and size options. To help protect the coil, Sonion offers a thin protective coating that provides maximum benefit to the windings of the coil. This protective coating adds protection during processing of parts and protection from environmental elements.

All telecoils are qualified to Sonion’s highest quality standards and come guaranteed with a quality certificate.
