Welcome to the ERNI world

As a leading manufacturer of connectors, ERNI keeps the world running in every area. In addition to manufacturing connectors, they offer a strong service portfolio: the electronics manufacturing services (EMS) range from electronics development through the assembly of printed circuit boards using pressfit or soldering technology to inspection technology, electronic packaging and cable connector assembly. And if the course of things in the world demands a new connector solution, naturally ERNI can also supply it.

About ERNI

ERNI Electronics is a leading global manufacturer and worldwide supplier of a broad line of interconnects for the telecommunications, data communications, computer, industrial and medical markets.

ERNI Electronics GmbH & Co. KG belongs to the international ERNI Group of companies specializing in electrical engineering and electronics. At present the ERNI Group employs some 650 people, achieving annual sales of around 150 million Euro. 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 leading distributors.


ERNI Electronics is one of the world's largest manufacturer of electrical connectors according to DIN 41612 standard. At the time of the founding of the ERNI Elektroapparate-GmbH by the Swiss parent company ERNI + Co. AG in 1956 consisted only of its product line relay.

ERNI in June 2006 celebrated its 50th corporate anniversary. After a steady period of growth produced ERNI Electronics in 1968 as the world's first manufacturer connector according to the new DIN 41612 standard, which became the world's most commonly used standard for industrial PCB-/Leiterplatten-Steckverbinder (PCB is an abbreviation for "printed circuit board ", in German, printed circuit board). In 1980, a distribution company was founded in the USA, which was later extended by a manufacturing site.

Continuous growth finally necessitated the centralization of all domestic production facilities in the newly built factory in Adelberg in 1992. Since July 1993 the quality management system certification in accordance with CECC / DIN ISO 9001. In 1997, the production site Adelberg due to capacity constraints has been increased by 75%, which corresponds to an extension of 7,500 m².

Mid-1990s, the connector series ERmet and SMC have been developed. The current product range covers PCB connectors and I/O connectors, backplanes (development, production and 100% testing), cable connectors, housings, systems, tools and presses.

Corporate philosophy

The claims made on connectors are the driving forces of Erni's quality system. ERNI is pursuing a "zero defect" production, followed by continuous improvement of corporate processes.

  1. 21.06.2019 - Optimisation of delivery times for various ERNI products

    In the last weeks and months ERNI was able to optimize the delivery times for the series M8/M12, MaxiBridge, SMC, ERmet and DIN41612 again and again.

    This has led to significant reductions in delivery times, which makes your planning and procurement easier.

    The optimisation of delivery times results from increasing capacities in production, relocation to further plants in Thailand or also from the independent work of some new employees in the production area.

    In addition, ERNI is currently working very acutely on a restructuring of production, which will also produce further positive effects.

    You can view the current replacement times for new production planning at at article level.

  2. 14.11.2018 - EVE meets ERNI Electronics

    We have been your reliable distributor for ERNI connectors and components for almost 20 years. We sealed this trusting cooperation again today with a personal meeting at electronica.

    This year ERNI is presenting a new series of M12 connectors with 12 and 17 poles.

    Over the last three decades, the M8/M12 connector system has established itself as that preferred device connection for use in rough environments which require a reliable, robust coupling solution.

    With various pin counts and a number of cable types, plug configurations and plug codings, the M8/M12 connector covers a wide spectrum of requirements.

    ERNI Electronics is now expanding its already extensive portfolio to include versions with higher pin counts.


    • high pin count in the standard M12 design
    • design-in suitable for the ERNI M8/M12 range
    • SMT, shieldable and suitable for automated processes
    • space saving for very compact device design
    • compensation of device interfaces
    • a single plug for bus, I/O, control, service and safety signals
    • enables more ports; for instance, for I/O boxes
    • M12 instead of M23 for multi-pin connections of valve terminals


    • sensors, cameras, scanners, rotary encoders
    • I/O boxes, sensor/actuator multi-pin connections

    These M12 connectors with 12 and 17 poles will be available shortly.

    You can already find a variety of M8/M12 circular connectors in our online shop.

    As an authorized distributor, we can of course supply you with the entire ERNI range.

    Your customer advisor is looking forward to your inquiries.

  3. 20.12.2016 - Product Change Notification DIN 41612 Female Connectors - ERNI

    Due to improvement of the manufacturing process the molding tool for female R, R/2 and R/3 DIN 41612/IEC 60603-2 connector housing has been modified. The protruding surface at the flanges has been removed. This change has no functional impact on the product and will not affect the quality and reliability of the above mentioned connector types.

    This product modification will be carried out as a running change without deadline.
    It can not be ruled out that deliveries contain mixed parts.

    Please not the Product Change Notification of the manufacturer.

    If you have any further question, please contact your personal customer advisor.

  4. 15.02.2016 - ERNI - D-Sub Slimline

    The ultra-slim D-Sub excels due to its space-saving design that distinctively reduces the board space necessary. Hereby, miniaturization and robustness of I/O interfaces in industrial applications are no longer incompatible.

    The slimline connector is available as plug and socket for fully-automated board assembly and is suitable for modern reflow soldering processes.

    Customer benefit: efficiency in board assembly and reliability in the field.

    Features / Benefits:

    • right angled plug and socket, 9 pin, SMT
    • dual-leaf spring contact guarantees excellent reliability
    • solderable retention pegs to absorb mechanical stress
    • lamella type shield fingers ensure a continuous ground path
    • current carrying: up to 4 A at 20 °C
    • tape and reel packaging for fully-automated board assembly
    • needs only 33% of board space (compared to a conventional model)

  5. 25.08.2015 - Program expansion : ERNI M8 / M12 Circular connectors and accessories

    Plug-in solutions can be implemented easily and quickly with the modular international circular connector system according to IEC 61076-2.

    M8 connectors are well known for the connection of small form factor sensor/actuator devices like proximity sensors, photoelectric barriers, cylinder switches, vacuum valves or micro switches. For such miniature devices it is essential to have space-saving components for reaching compact designs.

    M12 connectors are currently recommended as field bus connectors for almost all field bus specifications and are available in multiple codings.

    Now you may find several variations of M8 and M12 PCB connectors within our webshop. Suitable to your application you can choose between SMT- or THR-termination, straight or angled versions.

    M8 Circular Connectors
    M12 Circular Connectors straight
    M12 Circular Connectors angled

    Also an extensive range of accessories you are able to order online now.
