ERNI Electronics

ERNI is a manufacturer and supplier of a broad line of interconnects for the telecommunications, data communications, computer, industrial and medical markets. ERNI has manufacturing operations in Europe as well as sales offices in over 40 countries. ERNI products are also marketed via a worldwide network of representatives and distributors.

Company history

ERNI Electronics is one of the worldwide largest manufacturers of connectors in compliance with DIN 41612. At the time of its establishment by the Swiss parent ERNI + Co. AG in 1956 on the grounds of the former monastery of Adelberg the product range consisted solely of relays.

After a continuous period of growth in 1968 ERNI became the worldwide first manufacturer to produce connectors in compliance with the new standard DIN 41612. This standard has, by today, evolved into the most widely accepted standard for industrial PCB connectors in the world.As ERNI further expanded its operations in Europe, worldwide activity was not far away. The large U.S. market was opened up through a sales organization in 1980, manufacturing from 1986 to 2003 and current through ERNI Electronics Inc. in 2002.

Continuous growth let ERNI centralize its domestic production capacities in a newly constructed modern production plant at the Adelberg site in 1992. As a result of continuous growth, the production plant at the Adelberg site was expanded by 75% of its previous size at the end of 1997 ( +7,500 sqm). ERNI met the new requirements of the heavily increasing telecommunication market in the mid 90's and initiated a new growth with the design of the connector series ERmet and SMC. 2018 ERNI achieves IATF certification (ISO/TS 16949) with its two production sites in Adelberg and Lamphun.
