Sensata brake force sensors now in production EV braking systems

Sensata Technologies (NYSE: ST) announced its brake force sensors are being used in electromechanical braking (EMB) systems in electric vehicles currently in production, according to a company statement.

The sensors measure clamping force directly within the brake caliper and transmit data to a control unit at high frequency, enabling closed-loop control at each wheel. The design connects to the caliper control unit without additional connectors and is built on Sensata's Micro Strain Gauge technology, which the company says has been used in braking applications for more than 25 years.

EMB systems use electric actuation in place of hydraulic components such as brake lines and fluid systems. Accurate clamping force measurement is required to distinguish between different braking scenarios, from gradual deceleration to emergency stops.

"Electromechanical braking represents a fundamental shift in vehicle architecture, requiring a new level of precision in sensing and control," said Markus Schwabe, Executive Vice President and President, Automotive, Sensata Technologies. "Our brake force sensing technology enables OEMs to achieve accurate, real-time control of braking force at each wheel, supporting the performance, comfort and safety requirements of next-generation EVs."

Sensata is headquartered in Swindon, United Kingdom, and employs more than 16,000 people across operations in 13 countries.
