Proper Circuit Protection
Clothes dryers have had a history of being energy inefficient ranked only behind the refrigerators and freezers.
Like many modern appliances, clothes dryer designed with microprocessor based controllers allow the use of a variety of sensors to ensure proper, safe, and energy-efficient operation. Littelfuse’s magnetic sensor products help make these appliances as reliable as ever.
Reed sensors and Hall Effect sensors are both very reliable and will operate over millions of cycles with long-term integrity when used with microprocessor electrical loads. Both reed and Hall Effect devices are operated by a magnetic field. Reed switches and sensors consume no power, while Hall Effect devices are semiconductors and will consume a small amount of current in both the activated and de-activated state.
FEATURES AND BENEFITS OF HALL EFFECT SENSORS:
● No physical contact required to operate the sensor
● Wide operating temperature range
● Digital or analog options for output signal
● Programmable on both digital and analog applications for tight output tolerances
● Effective for high-speed applications
● Encapsulated sensors provide additional protection against mechanical stresses
● Long lifetime and reliable sensing for millions
of operations
FEATURES AND BENEFITS OF REED SWITCHES:
● Switch activation does not require physical contact
● Switch contacts are within a hermetically sealed capsule
● Resistant to moisture, dust, and other foreign objects
● Wide operating temperature range
● Reliable switching
● Long lifetime
