Connector Systems

Providing the manufacturers of hearing instruments with advanced connector systems and innoative solutions. This has enabled several successful hearing instrument launches and customizations have been frequent.


Trimmers are used to set the electroacoustic properties of the hearing instruments. Initially used for analog hearing instruments, the trimmers are now also used in digital hearing instruments, where programming is done by adjusting the trimmers.


Screws, nuts, bolts etc. are necessary when looking at the entire solution for hearing instruments.


Faceplates are the main mechanical building blocks in ITE (In-The-Ear) hearing instruments. We can provide selction of faceplates that covers all three battery sizes: 10A, 312 and 13.  For programmable systems, choose 10 IS, 12 IS, 13 IS or the fully modular CU 10.


The tapers are based on unique patented technology which allows manufacturing of smooth and accurate resistance tapers.
