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.

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.

Overall for the industry, shipments continued to climb in 2013, growing 13 percent, up from 11 percent in 2012. Revenue growth, however, was much slower at 2.8 percent pulled down by price erosion for components in safety applications such as electronic stability control (ESC) and tire pressure monitoring systems (TPMS). Price erosion is particularly pronounced for multisensors—or so-called combo sensors—used in ESC and now for roll-detection systems, contributing to slower revenue growth.

Bosch has a well-balanced portfolio and a strong position in safety applications that exploit MEMS sensors, in addition to automotive powertrain applications. It is the top supplier of accelerometers, gyroscopes, pressure sensors and flow sensors for cars. Denso is the top supplier of MEMS for heating, ventilation and air conditioning systems, and is also No. 1 in continuous variable transmission systems, at present mainly a Japanese market. Panasonic, meanwhile, derives most of its sales from the automotive gyroscope business.
