Senba Sensing Technology Co., Ltd., stock code 300701
Founded in 2005 and listed on ChiNext in 2017, Senba uses capital-market financing to expand sensor types/applications. In 2019 it wholly acquired US Alpha, becoming, according to the source, China's only company independently mastering capacitive micro-differential pressure sensor core technology.
In 2023 it acquired Wuxi Greentong Safety Equipment through share-based asset purchase. More than 20 years of combustible/toxic gas and flame detection expertise supported entry into high-end energy fire safety. That year, an investment in an acquisition fund acquired 100% of Aleph Electronics (Shenzhen) and all subsidiaries including Japan, Mexico and Hong Kong. Aleph originates in Japan's Ikuno Manufacturing, founded in 1936, and is described as a global top-three reed-switch manufacturer.
Senba now spans consumer, industrial and automotive sensors, diversified products and global operations as a multinational magnetic, optical and electronic sensor enterprise.
