SEM’s product portfolio consist of several business areas, from customised ignition systems for commercial vehicles – such as vans, distribution vehicles, buses or heavy trucks – to injector stators, sensors, solenoids and small engine ignition systems.

As environmental legislation becomes stricter, technical solutions to reduce emissions are being refined

Continuous research and design work keeps us competitive and as a result our products are recognized as environmentally friendly, top performing and cost effective.

One of our fastest growing product areas is ignition systems for engines run on biogas and natural gas. We provide customised solutions for heavy vehicles and stationary applications.
An important component, affecting engine emission levels, is the injector stator. Combined knowledge of mechanics and electromagnetism means that we can develop and manufacture stators that meet all requirements.

A major product area is also sensors. SEM manufactures inductive and contact-free sensors, designed to work in highly demanding environments.
