Featured Producuts

  • Temperature Sensors Temperature Sensors: A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal. US Sensor offers a wide selection of thermal cutoffs, including thermal fuses, compact threaded temperature switches, and more. Accelerate your design process by reducing hardware and software complexity compared to discrete temperature sensors, such as NTC thermistors and platinum RTDs, with Littelfuse's portfolio of temperature sensors. Littelfuse's temperature sensors allow you to overcome common design challenges and continue innovating with high-accuracy, low-power consumption, and small, flexible packaging options.
  • Thermal Cutoffs Thermal Cutoffs (Thermal Fuses) are devices designed to keep components safe in situations when an excessive temperature occurs. A thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. A thermal fuse must be replaced when it fails or is triggered.
  • Thermistor Probes and Assemblies Thermistor probes: Thermistor probes and assemblies are invaluable for sensing temperature in a variety of industries ranging from HVAC/R and environmental controls to automotive and white goods. Littelfuse standard and customized probes and assemblies offer very precise and extremely reliable thermal monitoring in the most demanding applications.
  • NTC and PTC Thermistors NTC and PTC Thermistors: US Sensor / Littelfuse Leaded thermistor options include the highly accurate precision interchangeable thermistors as well as high temperature axial leaded glass encapsulated thermistors and glass coated radial leaded chip thermistors. A wide variety of resistance values and tolerances are available.
  • RTD Probes and Assemblies RTD Probes and Assemblies: US Sensor / Littelfuse offers an extensive selection of RTD probe assembly styles to suit applications ranging from HVAC/R and foodservice processing to textile production and petrochemical processing. We use the most advanced manufacturing techniques to produce high-quality RTD probes and assemblies that meet or exceed the requirements of our customers.
