Injection Overmoulding PT100 PT1000 Temperature Sensor for Watertight Floor Heating System HVAC Refrigerator Freezer Application

Description:

refrigerator freezer HVAC NTC thermistor sensor cable assembly consists of a NTC thermistor soldered to a single insulated TPE extension cable. The sensor and the extension cable are moulded together as one hot vulcanised unit to give a high degree of protection against water/moisture ingress. Ideal from ambient air sensing in building management applications, heater controls, and air conditioning.


Features:
1. IP68 Rated
2. TPE Overmolded probe with probe head dimensions of Ø5 x 20mm
3. 22-24 AWG Jacket or Zipcord cable
4. Available in a variety of connector types
5. RoHS Compliant

Application:
Building Management Applications
Heater Control
Air Conditioning
