Over-moulded temperature sensors - TT0 Series

TTO series sensors are IP68 waterproof temperature probes encapsulated with thermoplastic elastomer materials in over moulding technology, specifically designed and dedicated for harsh environmental conditions.

High humidity levels, frequent freeze/thaw cycles or water may easily damage most conventional sensors. The over moulding technology used in the TT0 series guarantees an effective barrier against moisture ingress.

Excellent performance in extreme freeze-thaw conditions resulting from a wide choice of insulation material. The TTO over-moulded probes are a perfect solution for applications where the best waterproof and moisture protection is required. The probe is available in a wide range of standardized sizes and tolerances with a single, double or triple reinforced insulation. NTC, PTC, PtRTD versions are available.

Key Features:

  • Excellent insulation against moisture
  • Degree of waterproof protection IP68
  • Flexible size of tolerances (smallest tip diameter 4.5 mm)
  • Excellent resistance to UV (black insulation)
  • ROHS compliant and Halogen Free
  • Wide range of R/T characteristics
  • Marking possible on request
  • NTC and PTC thermistors, PtRTD versions are available
  • Cable remains flexible at minimum design temperature
