What bay sensortec does
Bay SensorTec GmbH is a privately held German sensor manufacturer founded in 2016 by Peter Bay and headquartered in Eching near Munich. The company develops, manufactures, and calibrates high-precision MEMS-based accelerometers (capacitive and piezoresistive), gyroscopes, inertial measurement units (IMUs), and current probes for demanding industrial measurement applications including automotive crash testing, rail vehicle monitoring, wind energy, aviation, and agricultural machinery. The firm claims to be one of only three global manufacturers of automotive crash sensors and emphasizes 100% in-house production in Germany, with products compliant to SAE J211 and an in-house DAkkS-accredited calibration laboratory under DIN EN ISO/IEC 17025:2018.
The product portfolio spans uni- and triaxial piezoresistive accelerometers (BST 10C through BST 28C series) for high-shock crash testing, capacitive accelerometers (BST K1 series) for low-amplitude and DC measurement, gyro sensors (BST 83G series), 6DoF IMUs (BST IMU-C/CC/M), current probes (BST CU series), and the newly launched BST RAIL 42 rail-specific acceleration sensor. Sensors are configurable in housing, cable, connector, filter, and IP protection class, and Bay SensorTec accepts custom adaptations and small-series production. Manufacturing, engineering consultation, and calibration all occur at the single Eching facility.
Bay SensorTec operates a sales-led, quote-based B2B model with revenue generated through one-time hardware sales and fee-for-service calibration. It distributes directly from Germany and through a global network comprising six regional distributors (Taiwan, Korea, China, Spain, North America, France) plus a strategic global partnership with Kistler ATD GmbH for crash sensors. The company markets itself via its website, content downloads, social media, and dedicated account managers rather than through volume e-commerce channels, consistent with a niche, engineering-driven industrial business.
