Export Administration Regulations (EAR) and/or the International Traffic in Arms Regulations (ITAR) as applicable.

Space rated thermal switch with internal temperature sensor.

  • Customers can choose from wide range of wire wound sensors in almost any configuration.
  • Flat wound strip sensors start as thin as 0.020" and our thermal sensing coil wound probes begin with diameters as small as 0.25".
  • Whenever quality, precision and durability are important, Honeywell can make a wire wound resistive thermal sensor to fit the application.
Thermal Sensors
  • Honeywell measurement and control devices are found on every Boeing and McDonnell Douglas commercial jet built.
  • Honeywell is a key thermal control supplier for a long history of military aircraft platforms - both fixed wing and rotor wing craft.
  • Our thermal switches are standard on numerous business jets.
