Housing Technology

– high-precision injection moulded plastic housings –

Miniaturised sensor technology is sensitive and must therefore be protected from external influences and mechanical damage. 2E mechatronic manufactures high quality, high-precision sensor housings using fully automated processes. Thanks to modern housing technology with regard to inserted parts such as bushings or pins, products can also be adapted to satisfy almost any customer requirements.

  • Housing for
    Side Airbag Sensors

    This type of housing for side airbag sensors contains overmoulded nickel/chrome bushings as well as 2 overmoulded press-fit pins and 2 contacts in the integrated connector for connecting to the onboard electronic system.

  • Housing for
    Side Airbag Sensors

    Housings to accommodate the electronic parts for side airbag sensors are produced by 2E in very high quantities on fully automatic machines. The basic material for the housings is tried and tested polybutylene terephthalate, in short PBT.

  • Housing for
    Start Stop System

    The automatic start/stop system is also used in commercial vehicles. It reduces consumption and CO2 emissions, especially when there are frequent stops. Sophisticated housings for sensors are produced by 2E.

  • Housing for Yaw Rate Sensors ESP®

    Yaw rate sensors are an integral part of driver assistance systems, in this case the so-called ESP® (Electronic Stability Programme). 3rd generation MM3.

  • Housings for MM5/MM7 yaw rate sensors

    The considerably smaller housings of the MM5/MM7, the follow-up generation of the MM3, are also proof of the constant further development of integrated sensor technology. The tried and tested press-fit technology is once again in use here.

  • Housings for NOx sensor electronics

    NOx sensors are a part of the exhaust aftertreatment system in vehicles. NOx refers to various gaseous oxides of nitrogen that, among other things, are produced by the combustion of fossil fuels.

The manufacturing process of a plastic housing
Basically, the manufacturing process of a sensor housing can be divided into four stages. In the first stage the individual parts (pins, bushings) are inserted in the injection mould. The parts are subsequently precision injection moulded. Stage three involves checking that the housing is complete, sealed and dimensionally accurate as well as testing for short circuits. In stage four the sensor housings are packed in KLT boxes. The advantage of fully automated production is that deviations can be minimised. Once processes have been adjusted, they can be carried out with great precision and in large quantities. An excellent example of modern housing technology is the housing for the MM5/MM7 rotation rate sensors, which measures only 54x80x21mm.

Top class plastic housing – materials and properties
One of the most frequently used materials is polybutylene terephthalate, in short PBT. With its high dimensional stability it can be processed very well. Furthermore, its good heat resistance makes it an ideal material for the widely ranging temperatures in a car. Its high tensile strength and resistance to mechanical wear and tear help the material to withstand vehicle vibrations over a long period. In addition, PBT has a good chemical resistance to most solvents.

Areas of application for 2E mechatronic housing technology
Individually manufactured housings are predominantly used in the automotive industry. As a certified supplier according to DIN ISO/TS 16949 the quality requirements in every process are met. Examples include the manufacture of housings for:

  • Rotation rate sensors as part of the ESP

  • Start-stop control systems

  • NOx sensors as part of the exhaust system

  • Side airbag sensors
