Sensors for Appliances

Sensor technologies in household appliances are contributing to new levels of convenience and productivity for the smart home of today and tomorrow.

Appliances create their own unique challenges based on the environment they are creating. Sensors in many cases are put into a position to measure in the challenging environment.  For example, a sensor can be used to measure humidity and temperature in a dishwasher.  While our dishes and forks are cleaned with water jets spraying, elevated temperatures and high humidity, it creates unique challenges for sensors to survive humidity while producing an electrical output signal.  In similar cases, we cook food in ovens to ensure our meals are safe to eat.  Building a temperature sensor to ensure the meat is cooked completely requires the survival of the sensor and cabling at elevated oven temperatures. Various sensor types are manufactured with the customer in mind. Through relationships with major manufacturers, TE Connectivity (TE) helps create smart appliances that respond to human touch, sense vibration, adjust to loads, and operate more efficiently. Our global network of engineers offers custom solutions to meet customers’ exacting requirements. Fast-paced product development time lines are met with rapid prototyping as TE creates solutions for its customers. Leading products include:

Applications

Today’s smart and green appliances are built using more efficient designs, meeting the latest regulations while saving energy, water and time. Customers rely on our sensor technologies to enable appliances to respond to human touch, sense vibration, adjust to loads, and operate more efficiently. We work to develop custom solutions that can monitor humidity, water levels, position and temperature. Our products contribute to new levels of convenience and productivity in a wide range of household appliances.
