IKA GmbH was the first company to position itself as a partner in the independent aftermarket for SEG Automotive GmbH products. Following the spin-off of the Rotating Electric division from BOSCH, SEG is one of the world's leading original equipment manufacturers for starters and alternators.

IKA GmbH offers the complete aftermarket program for cars, trucks, construction machinery, agricultural machinery and stationary industrial equipment.  

With a comprehensive range of relays, fuses and sockets, the GEBE brand offers a complete portfolio for the wiring harness.

In addition to all common automotive spare parts, in-house programming enables the production of individually specified time switch relays for the industrial sector.

Ultra Micro Relays, Micro Relays, Mini Relays, HD-Relays, Preheating Relays, Flashers/Pulse Generators, BSR-Relays, Timer-/Multitimer-Relays, Fuel Pump Relays, Sockets. 

The electrical range of the GEBE brand offers components for the repair and remanufacturing of starters, alternators and generators in the automotive sector and for industrial applications.

Our portfolio includes:

Carbon Brush Systems, Solenoids, Regulators, Rectifiers, Bearings and Needle Bearings, Overrunning Pulleys, Slip Rings.

Technology and environment

For the Euro 6 emission standard, the NOx sensor is the most important link between the engine management system and the SCR exhaust aftertreatment. The sensor takes over the measurements of the lambda probe required for mixture preparation and also records the proportion of nitrogen oxides in the exhaust gas. This highly complex method of measuring chemical parameters takes place in real time. Without precise measurement results from the NOx sensor, the amount of urea (AdBlue) cannot be determined correctly and the SCR catalytic converter does not deliver the required conversion rate of the nitrogen oxides.

Wear and Consequences

Due to the use at high ambient temperatures in the exhaust system, the reaction behavior of the ceramic measuring head changes during the mileage. As a result, the broadband measurements are inaccurate and no longer match the target values ​​of the control unit. The self-monitoring of the sensor results in a fault memory entry due to the faulty exhaust gas cleaning; the vehicle goes into the emergency mode, the NOX sensor must be replaced as soon as possible.

Therefore GEBE

With over 500 different products, the GEBE portfolio already covers all relevant applications in the areas of cars, vans, trucks and commercial vehicles. Through constant further development on the market, we always keep our range technically and application-related up to date. In our own test laboratory in Königswinter and the connected test centers, we can also map different software versions in addition to runtime tests, the simulation of environmental influences and the interactions in the exhaust system, thus guaranteeing the high quality and operational readiness of our GEBE products.

Electronics & Sensors

In the Electronics & Sensors division, IKA Germany offers a comprehensive and constantly growing portfolio for engine control components and exhaust system (SCR) sensors.  

NOx sensors, EGR valves, Oxygene sensors, Exhaust Gas Temperature Sensors, Exhaust Gas Pressure Sensors, Air Mass Meters, Fuel Pumps and Ignition Coils and Modules.

Our comprehensive range covers all relevant applications for PC, LCV, Truck and HD.
