What CHEN YANG LIMITED does

ChenYang Technologies (HK) Co., Limited is the Hong Kong-domiciled international sales and distribution entity of the Chen Yang group, established in March 2013 and registered with the Hong Kong District Court under business register number 61172680. The company commercializes German-engineered Hall Effect sensors, fluxgate sensors, current and voltage sensors, speed and position sensors, magnetic measuring instruments (including the CYGM99A Gaussmeter), and custom permanent magnets (NdFeB, SmCo, Alnico, hard ferrite) and soft ferrite cores. Core technologies are developed by the German parent Chen Yang Technologies GmbH & Co. KG (founded 2002 in Finsing, near Munich) and include analog/digital signal processing, system calibration and error compensation, and digital self-correction algorithms, with manufacturing carried out in Germany and through the Shanghai subsidiary SONNECY Technologies (Shanghai) Co., Ltd. (founded December 2013, with partner capacity of approximately 300 CNC machines and measuring instruments).

The business operates two product streams: (1) sale of standard catalog sensors and measuring instruments plus fully customized sensor/systems developed against customer specifications, and (2) custom CNC machining, sheet metal, forging, stamping, and injection molding services for metal parts serving automotive, medical, industrial equipment, optical instruments, and telecommunications applications. Pricing is not publicly disclosed; sales are conducted via direct email, phone, and the company website, with a multi-language pre-sales technical team (German, English, Chinese). The Hong Kong headquarters coordinates international sales to Hong Kong, Taiwan, Asia, Australia, and America, while European customers are served via the German parent and mainland China customers via the Shanghai subsidiary. The group is ISO 9001:2015 certified by TÜV SÜD Management Service GmbH (upgraded from ISO 9001:2008 in August 2015), RoHS compliant per SGS testing under EU Directive 2015/863, and holds the SONNECY trademark in both the EU and China.

The company serves industrial customers (variable speed drives, servo drives, UPS, SMPS, welding power, pumps/fans, elevators, HVAC), energy and automation customers (solar photovoltaic, wind power, process automation, facility management), and automotive customers (battery monitoring for EVs and hybrids, fuel cell current control, motor inverter drives, vehicle speed and position measurement). All products carry standard output signals (0-4V, 0-5V, 0-10V, 0-20mA, 4-20mA) for direct system integration. The company is privately held with no external venture or institutional investment disclosed, and no AI/ML capabilities are evidenced in the product portfolio or R&D focus.
