What a Sensor Sees – in AUTOMOTIVE

Sensors in Vehicles

Sensors enable the ability to measure parameters such as pressure, temperature, and humidity to make cars more efficient, increase performance, and safer.

Lighter. Faster. More efficient. With an increase in the number of vehicles being operated and developments of technology, automotive manufactures are consistently looking for improvements to vehicle platforms.  From traditional diesel and gasoline engines to electric and hydrogen powered vehicles, TE Connectivity (TE) manufactures sensors to capture the data from the testing of the car to full production vehicles to enable a greener means of transportation. 

  1. Enabling Cleaner Diesel Engines

TE's Marcus Schulte describes how we work with our customers to help limit vehicle emissions. One example is a sensor we created to measure the quality and concentration of urea in systems that reduce the amount of greenhouse gases created by diesel engines.

Sensors experience the same conditions of other components within the vehicle.  From elevated engine compartment temperatures to salt water submersion conditions, TE sensors are designed and manufactured to produce advanced performance in harsh environmental conditions.  Our product testing capability includes elements such as aging, vibration, corrosion, sealing, and thermal shocks.  Additionally, sensors are produced with analog and digital output signal outputs to simplify integration and optimize performance.  These signals are tested and certified to survive automotive standards in Electro-Magnetic Interference (EMI) and Radio Frequency Interference (RFI). TE sensors can be designed, packaged, and tested to ensure continued operation in the harshest environments.  Additionally, TE offers several sensor platforms that measure multiple parameters from a single sensor.  The Trican HTD2800 pressure, temperature and humidity sensor installed into the intake manifold send data to the Engine Control Unit (ECU) to optimize performance; board mountable components such as the MS8607 can also measure multiple parameters in a compact package.  

What happens when TE Connectivity sensors meet a race car? TE is increasing performance by providing data to make smarter decisions.  See how TE sensors are used in race applications, from gearbox oil pressure and temperature to rear suspension monitoring through interviews with the Andretti team.

What a Sensor Sees – in Aerospace

BRAKES

Our brake sensors are used in vehicle applications such as travel sensor for brake master cylinder position (optional redundancy), travel sensor for rear axle steering, rotary sensor for brake pedal position detection (optional redundancy); contactless brake light switch and wheel speed sensor. We also provide pressure sensors such as the vacuum brake booster sensor and brake line pressure for ABS/ESC modules.

CHASSIS

We provide a range of chassis solutions for roof and convertible switches, actuator and cylinder position, seat position and weight classification. Our humidity and temperature technologies are used in Heating, Ventilation and Air Conditioning (HVAC) systems to prevent wind screen fogging and for energy management.

CLUTCH

The clutch sensors are used in vehicle applications such as Permanent-magnetic Linear Contactless Displacement (PLCD) sensors for concentric slave cylinder and clutch slave cylinder, rotary sensors for clutch pedal position detection; contactless switch for clutch master cylinder and travel sensor for clutch master cylinder and Dual Clutch Transmission (DCT).

ENGINE / E-MOTOR

Our engine and e-motor sensors are used in vehicle applications such as position sensors for turbo charger actuator, pneumatic (EGR) Cylinder, CAM and crank shaft speed sensors and resolvers for e-motor commutation.

EXHAUST

TE provides a range of sensors for exhaust gas applications, such as urea quality, level and temperature, urea pump pressure and exhaust gas temperature (EGTS). These sensors help the OEM to comply with the latest emission regulations and significant performance improvement of modern after-treatment systems.

TRANSMISSION

TE’s transmission sensors are used in vehicle applications such as all gear / neutral detection for manual transmission (MT) to support start and stop function, drive mode (travel or rotary) for automatic (AT), continuously variable (CVT), or dual clutch (DCT) transmissions. We also provide pressure and temperature solutions.
