Electromagnetic compatibility for automotive and mobile vehicle sensors

Novotechnik, the German sensor designer and manufacturer represented exclusively in the UK by Variohm EuroSensor, has recently announced that two of its non-contacting sensor models have gained E1 approval according to the UN/ECE R10 environmental compatibility category for interference emission and immunity. The approval, by the German Federal Motor Transport Authority (KBA), permits the RSC-2800 and RSC-3200 sensors to be used throughout Europe on vehicles such as cars or buses, and also extends to mobile machinery such as agricultural machines, diggers or cranes that may run on roads reaching speeds or more than 25km/h. Both sensor types benefit from Novotechnik's specially developed contactless non-contacting Hall Effect principle where the orientation of the magnetic field is measured. The ECE-R10 (E1) approval applies to ratiometric output versions with the RS-2800 offering a redundant output. Both model families offer extremely compact wear-free designs with exceptional performance against extreme environmental conditions such as high temperatures, shock and vibration. Aimed specifically at automotive applications including throttle, EGR valves, transmission gear and accelerator position measurement etc., the RSC-2800 also fulfils measurement solutions for arduous industrial, agricultural, mining, port & marine, and other harsh environment equipment. Both types are also available with many other environmental, mechanical and electrical interfacing options through their respective product ranges, says the company.
