Plug connections and central electric units for construction machinery

Construction machinery such as excavators, caterpillars, milling machines or pile drivers and drills provide immense performance and often perform their work under adverse conditions. This makes it all the more important that they function reliably and that the components used for the machines are of high quality. ERNI offers a wide range of connectors, central electric units and power elements for applications from A to Z such as ABS to fuel pumps and headlights to accessories.

From development and provision of sample parts to series production, ERNI offers all important services and addresses various areas of construction machinery such as driver cabs, drives and exteriors. Both modular standard central electric units and customer-specific central electric units are provided.

Advantages of ERNI connectors and central electrical units

High current carrying capacity
Plug connections and central electric units enable the transmission of high currents. ERNI has extensive know-how in the assembly of printed circuit boards and the use of pressfit technology.

Continuous reliability
The products have reliable locking systems and always work reliably - even under rough conditions. Vibrations and shocks have no influence on the connection quality.

Low sensitivity
The pressfit technology used for the central electric units ensures greater insensitivity to thermal and mechanical stress. The modules are easy to assemble, require little maintenance and are robust.

Economical use
Central electrical units based on printed circuit boards are less prone to faults than cable harnesses and require less space. At the same time, their use reduces maintenance costs.

Connectors and central electric units for every construction machine

In our product range you will find connectors and central electric units for reliable use in numerous construction machines.

High requirements for high-performance machines in the building industry

Central electric units and connectors for construction machinery must provide high performance under extreme conditions. Shock, vibration and temperature resistance are basic requirements for use in machines. The products must also support the high currents that occur. The use and assembly of the components should be as flexible, simple and economical as possible. Furthermore, breakdowns must be avoided at all costs and maintenance efforts must be kept to a minimum so as not to impair the productive performance of the construction machinery.
