Achieve the smallest most powerful and reliable connections with estron’s up to 8 conductors ready to use es-Linum® cables without compromising strength and durability

es-Linum® is a unique high-tech cable developed by estron. The cable is thin, strong and almost invisible. The cable is made from ESW - silver-plated copper wire and strengthening fibres. It is extruded with formable Pebax - and has an OD of Ø0.9 mm. As opposed to a tube, es-Linum is not hollow. No sound waves will pass through, and thus acoustical feedback is reduced. Moreover, no sweat, moisture or ear wax can enter the inside of the jacket. The cable is tested and approved for cochlear use.

Ideal for applications within Hearing, Medical, OTC, Audio, Communication and similar.
