HVAC Sensors
Air flap position sensors
HVAC sensors feedback the position of the cold/hot air flap dampers in automotive HVAC systems (flap motor positioning) with high accuracy (2% linearity) at competitive cost. Piher has delivered over 120 million HVAC sensors with a PPM rate below 1 to automotive suppliers.
Piher can also build custom resistive tracks for HVAC thermal management actuators by printing resistors on several substrates that seamlessly adapt to any given customer specific application.
