our history

We were born in 1965 with the manufacture of audio connectors.
In the 80’s, audio connectors were progressively abandoned to focus on RF coaxial connectors for professional telecommunications: UHF, F, BNC, TNC, N series.
In the 90’s comes the consolidation of coaxials with new series, power as 7/16 or microcoaxials for microwaves, as well as RF devices. At the beginning of this decade we participated in the birth of private TV in Spain and its expansion.
In the second half of the 90’s, our company participates in the development of GSM repeater stations, being a supplier of the main mobile telephony operators.
The 2000’s are marked by the modernization of the company, in means of production, quality policies, security, and internationalization.
Later participates in the deployment of DTT, providing connectors and cabling to major operators
In 2010, the coaxial-RF connectors division is strengthened by introducing new products and the MultiContact connectors division is started, with which the connectivity offer is substantially broadened. From now on, also in the electrical sector.
And we continue to think and develop new products that make connectivity easier, more versatile and safer.
