headquarters horten norway products gyros imus pressure sensors number of employees 60 website http www.sensonor.com sensonor as is a norwegian producer and developer of mems gyro and pressure sensors . sensonor was owned by infineon technologies from june 2003 1 until february 2009 2 under the name infineon technologies sensonor . in this period the company was world leading in the tpms market . since 2009 the company has focused on mems gyros and the main product line has been the gyros stim202 stim210 and the imu stim300 . the company has 60 employees and is localised in vestfold norway with offices and fabs in horten front end and at skoppum back end . ceo is j rgen bredesen . contents 1 business 2 history 3 references 4 external links business edit the main product of sensonor has long been mems manufactured pressure sensors and gyros inertial measurement systems . after the transition into an independent company the company has made it clear that it wants to develop new products in the gyroscope and night vision business . 3 the main products are the inertial measurement units stim210 and stim300 . 4 history edit the company was first established in horten in 1985 and was founded on knowledge and research from akers electronics . 5 in the 1990s sensonor had international success with sa20 a sensor for airbag systems . it was made up of a piezoresistive beam of silicon . 6 around 35 million sensors were sold all over the world and the company had an estimated 60 70 % of the european market for airbag sensors . 7 however sensonor failed in developing their next generation of the crash sensor sa30 which was eventually given up . 8 this led to a decrease in the revenues from 170 mnok in 1997 to 50 mnok in 1999 . 9 thus the early 2000s decade were economically difficult years for the business and stock market speculation increased the instabilities . eventually sensonor was purchased in full by the large german semiconductor company infineon technologies . 10 in parallel with the development of the sa30 sensor sensonor had also been working on a pressure sensor named sp12 . it was designed for usage in tpms applications i.e. monitoring of the air pressure in car tires . as with earlier products sp12 was also based on piezoresistive elements implanted in a silicon crystal but additionally the silicon wafer was encapsulated between two pyrex glass wafers . 11 12 it was this technology which made the norwegian company an interesting investment for infineon . 13 later sensonor developed improved versions sp30 and sp35 . today these are still sold to producers of tpms systems through cooperation with infineon . in february 2009 infineon announced that sensonor were to be sold to norwegian private investors in a move that would benefit both sensonor and infineon . 14 in february 2012 the company filed for bankruptcy and in april 2012 new owners purchased the estate and reestablished the company . 15 references edit smalltimes.com 23 . juni 2003 infineon sensonor agrees to acquisition tu.no 20 . februar 2009 sensonor igjen p norske hender gjengangeren.no 18 . february 2009 eierskifte skaper handlingsrom sensonor.com 12 . april 2012 forskning.no 10 . oktober 2002 mikroelektronikkens grand old man hive.no 20 . februar 2009 hibu.no 20 . februar 2009 etn.se 1 . april 2000 forskning.no 10 . oktober 2002 mikroelektronikkens grand old man smalltimes.com 23 . juni 2003 infineon sensonor agrees to acquisition sensonor.no 20 . february 2009 tpms technology hive.no 20 . februar 2009 sensonor sw4 intro smalltimes.com 26 . juli 2006 tire sensor maker ready to take u.s. market for a ride tu.no 20 . februar 2009 sensonor igjen p norske hender gjengangeren.no 30 . mars 2012 nye eiere p sensonor external links edit http www.sensonor.com retrieved from https en.wikipedia.org w index.php title sensonor & oldid 700568113 categories science and technology in norwaymanufacturing companies of norwaysemiconductor companies of norwayhidden categories use dmy dates from may 2011 navigation menu personal tools not logged intalkcontributionscreate accountlog in namespaces article talk variants views read edit view history more search navigation main pagecontentsfeatured contentcurrent eventsrandom articledonate to wikipediawikipedia store interaction helpabout wikipediacommunity portalrecent changescontact page tools what links hererelated changesupload filespecial pagespermanent linkpage informationwikidata itemcite this page print export create a bookdownload as pdfprintable version languages norsk bokm l edit links this page was last modified on 19 january 2016 at 08 12 . text is available under the creative commons attribution sharealike license ;
