Sensata Technologies introduces its smallest micro-fused strain gage for next-generation brake systems for hybrids and EVs

Sensata Technologies, a manufacturer of sensing, electrical protection, control and power management solutions, has developed a line of smaller, lighter Micro-fused Strain Gage (MSG) pressure sensors for use in next-generation brake systems for hybrid, electric, and conventional vehicles. The eXtra-small Form Factor (XFF) sensor is available for design-in beginning January 2016.

To ensure traditional braking feel in hybrid and electric vehicles, brake systems require additional pressure sensors. By offering our caliber of pressure sensing in a smaller, lighter package, our customers can adopt multiple sensors without growing their module.

—Jeff Silveria, Sensata’s Performance Sensing Segment manager for global chassis

Sensata’s automotive MSG pressure technology will now be offered at less than 5 grams, with a body diameter less than 7.8mm, and a height less than 30mm, including its revolutionary spring contact system. This provides system manufacturers with a new degree of design flexibility and including industry leading performance. The new XFF platform utilizes a modular port design, catering to a wide-range of system pressures, and a modular circuit architecture offering high-fault-detectability enabling system manufacturers to meet technical safety requirements associated with ISO26262.

Sensata’s MSG technology offers analog and digital integrated pressure and temperature signal conditioning delivering an accurate, stable signal over wide operating temperature (-40° to +140° C) and pressure ranges.

Beyond hybrid and electric vehicles, this MSG form factor is ideal for integrated brake modules which eliminate the vacuum booster. This development enables improved fuel economy and enhanced emergency braking performance in all vehicle types.
