Temperature sensors, TTO series, overmoulded

Manufacturer's part number :

TTO series

Manufacturer Tewa


Description :

TTO series sensors are IP68 waterproof temperature probes encapsulated with thermoplastic elastomer materials in overmoulding technology. Excellent performance in extreme freeze-thaw conditions resulting from a wide choice of insulation material. The TTO overmoulded 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.
