Custom potentiometers and position sensors

Sensors & controls used in automotive


Piher´s position sensors and controls are widely used in the land vehicle market. There´s scarcely a car that does not carry Piher´s sensors or controls

The Automotive market is one of the key drivers of Piher’s success. Demanding new and cost effective ideas year on year has shaped the company in to what it is today: proactive and customer driven. Since the seventies Piher has served the key Asian, US and European Automotive OEM’s and component suppliers and has developed an expertise in providing custom Control and Sensor solutions unrivalled in today’s thriving Automotive sector.

Our in-car position sensors afford built-it magnetic stray field immunity to provide stable output even near high-current wires. We provide cost effective sensors that improve vechicle performance and safety.

Thanks to sensors, cars are getting "smarter", more efficient, and safer in critical systems such as braking and power steering. Piher sensors play an important role in non-critical safety systems too,such as electronic stability program (ESP), vehicle dynamics complex mechanisms, body hardware, suspension systems, body structures and climate control (HVACR) systems.

Typical applications for automotive-grade sensors and controls are:

• Cornering/bending lights position sensor
• Heating, ventilating + air aconditioning
• Instrument Panel light dimmers / Headlamp levelling / Headlamp switches + Interior light control
• Mirror memory
• Infotainment
• Windshield wiper & blinkers control potentiometer
