Temperature sensing and control are among the most important and wellestablished functions in automotive
electronics. In automotive electronics they are found especially in climate control and powertrain applications.
In recent years we have introduced a great variety of new sensors and sensor systems to the automotive market
and continuously develop innovative products to meet customers’ requirements.
EPCOS sensors stand out for excellent measuring accuracy and longterm stability. Advanced technologies allow
costefficient and largescale production of reliable sensors. Thus, we are able to offer sensors overmolded with
plastic or encapsulated in specific materials for reliable use in adverse environments for a large range of tempera
tures. They can be delivered in numerous shapes and with a wide variety of cable and connector geometries.
If standard types do not match the purpose – we can also supply applicationspecific sensors with customized
parameters.
Our design centers and plants for sensor products – in Berlin, Germany, Deutschlandsberg, Austria, Zhuhai, China,
and Batam, Indonesia – are certified to ISO 9001:2008, ISO/TS 16949:2009 and ISO 14001:2004.
With our comprehensive sensor portfolio we help automotive manufacturers make their products safer, more
convenient to use and more energyefficient.
This product brief can only present a selection of our continuously growing portfolio of both temperature and
pressure sensor products.
In addition to the presented temperature sensors, we also offer an extensive range of pressure sensors that are
suitable for automotive industry. For example, pressure sensors can be used to measure the pressure of various
media and thus support engine management and safety systems. Such sensors are needed to achieve precise
engine control for low fuel consumption and to enable exhaust gas treatment for a reduction of harmful emissions.

Climate Control
Climate control
Effective airconditioning helps
drivers keep a cool head in the most
tricky situations and minimizes the
Solar sensor stress on passengers. The control
Air NTC 6 of the airconditioning system can
be based on the temperature at the
evaporator or in the air streams of
Evaporator every outlet carrying air to the feet
ECU or body of the passengers.
NTC 2
NTC 3 NTC 4 One effect that temperature sensors
are unable to detect is the warmth
NTC 1 of direct sunlight that passengers
NTC 5 Heater feel on their skin. In this case, solar
sensors can be used to evaluate
the intensity and in many cases the
direction of incoming solar rays.
