Piher sensors and controls - custom potentiometers and position sensors

HVACR Sensors

Driven to perfection

The HVAC sensor family  has been designed to feedback the position of  the cold/hot air flap in the car´s HVACR system. High accuracy (2% linearity) and low cost are among its main advantages.

Over 120 million-plus HVAC custom sensors, delivered to a major automotive supplier, for over ten years with an PPM rate below 1 are some the impressive figures achieved by Piher for motor control feeback sensing applications related to HVAC.
