Five core technologies under one roof — short distances, high quality, maximum flexibility
From development to manufacturing to testing: KE Elektronik brings together key technologies for custom cable assembly and connector solutions under one roof.
A reliable connection isn’t just created during production. It begins with the design phase, continues through the selection and processing of components, and must ultimately be capable of being tested reproducibly and manufactured economically in series production. That’s why we take a holistic approach to development, connection technology, plastic injection molding, wire processing, plant engineering, and testing technology. For you, this means: streamlined technical coordination, seamlessly integrated processes, and solutions that are designed from the outset with future mass production in mind.
Fewer interfaces. Greater technical synergy. The fact that KE Elektronik combines these technologies is not an end in itself. The real benefit arises where the individual areas of expertise interlock.

Turning signals into reliable data.
Cameras, radar, lidar, and other sensor systems are generating ever-increasing amounts of data. It is crucial that this information be transmitted reliably and with consistent signal quality between end devices and control units. KE Elektronik develops wiring harness and connector solutions for state-of-the-art in-vehicle data applications—supporting all relevant in-vehicle data protocols. We take a holistic view of the entire connection, from the connector to the automated processing of data lines, ensuring that your sensor systems communicate reliably even under real-world driving conditions.
High performance. Securely connected.
Electric mobility places high demands on performance, current-carrying capacity, temperature resistance, sealing, and installation space. To ensure a reliable overall system, the wiring, contacts, and connectors must work together seamlessly. KE Elektronik develops and manufactures custom high-voltage and high-current wiring harnesses for demanding automotive applications. Working closely with you, we create a connection solution that takes into account performance, weight, installation space, and suitability for mass production.
Reliable connection technology for temperature control in vehicles.
Failures in thermal management systems are rarely caused by individual components, but rather by the connections between them. We develop and manufacture custom wiring harnesses and connection systems that can withstand continuous vibration, temperature fluctuations, and the effects of process media. With our own material validation, APQP-driven processes, and flexible in-house equipment manufacturing, we guarantee maximum reliability even in high-temperature applications. Our in-house testing laboratories and internal equipment manufacturing ensure the highest level of media resistance and rapid adaptations—from prototype to series production.
Connections for demanding environments.
Exhaust gas sensors operate in environments where temperatures and conditions pose particular challenges for electrical connections. At the same time, measurement signals must be transmitted reliably and consistently to the control electronics. KE Elektronik develops connection systems for applications in exhaust gas sensor technology, such as NOx and lambda sensors. Specially tailored contact and housing solutions ensure that electrical properties and connection reliability are maintained even under high thermal stress. Automated manufacturing and testing processes ensure consistently high quality in series production.
Reliable connections for gearboxes.
Inside the transmission, high temperatures, vibrations, fluids, and limited installation space place constant, demanding requirements on electrical connections. KE Elektronik develops custom cable harnesses and connection solutions for applications related to transmissions, drivetrains, and engine cooling. In doing so, we take into account your requirements for sealing, electrical contact, mechanical durability, and reliable operation across the entire operating range. The result is connection technology that not only works in the prototype vehicle but is also designed for series production.
Comfort often begins with an invisible connection.
From smart convenience systems — such as the automatic tailgate — to high-speed data cabling. While this all seems effortless to the driver, the technology behind it involves a complex interplay of actuators, sensors, control units, and electrical connections. We develop custom wiring harness and connector solutions for in-vehicle electrical comfort features. We tailor the wiring harness, contacts, sealing design, and integration to your specific application, creating a solution that can be reliably integrated into your system and your mass production process.
