Bosch remained the number one supplier of automotive microelectromechanical system (MEMS) sensors, a market in which shipments continue to expand strongly but where revenue is being squeezed by average selling price erosion, according to HIS.
Bosch grew faster than the average of the market and, with revenue of $740 million, consolidated its lead at the top of the ranking of vendors compiled by IHS. It enjoyed more than three times the sales of its nearest competitor, Denso of Japan. Denso's sales fell by 21.3 percent, largely due to weakening of the yen against the dollar, but the company did not lose ground.
Top ten automotive MEMS suppliers ranked by revenue in 2013 in millions of dollars.
The other notable change was the fall of Japan's Panasonic. It too suffered a contraction of sales by 21.3 percent but that cause it to fall from third spot in 2012 to seventh in 2013, allowing those behind it to rise by one place. Similarly affected were other Japanese-based auto MEMS suppliers not in the top 10, such as Epson Toyocom and Fuji Electric.
The second tier of supplier behind Bosch, is now closely packed with annual sales of between $137 million and $233 million.
