Thermistor NTC, B‑value 3950 — 10KΩ @ 25°C, ±1% accuracy Why this sensor matters Accurate temperature readings you can trust: 10KΩ at 25°C with ±1% accuracy ensures consistent control and repeatable monitoring for HVAC, refrigeration, water heating and appliance applications. Built to survive wet and harsh environments: a sealed probe and robust insulation protect the sensor where moisture, steam or vibration are present. Fast, stable response for reliable control: low thermal constant (max 12 s) and an optimized dissipation coefficient give quick detection and steady readings for faster system reactions. Key features and benefits Precise sensing: Thermistor with B‑value 3950 delivers predictable NTC behavior and accuracy for temperature compensation, feedback loops and safety cutouts. Waterproof probe: sealed 4 × 20 mm copper‑plated silver tip resists corrosion and improves thermal contact for dependable long‑term performance. Durable construction: double‑layer insulation plus PVC‑coated wiring reduce wear from flexing and exposure, extending service life in appliances and industrial equipment. Electrical safety: wire assembly rated to withstand up to 300 V, suitable for integration into a wide range of control circuits. Fast response time: maximum thermal time constant of 12 seconds enables quick detection of temperature changes in ovens, dryers and control systems. Easy integration: 1 meter cable terminated with an XH2.54 connector for simple plug‑in installation; custom cable lengths available on request. Applications (practical examples) HVAC — temperature sensing for air handlers, duct monitoring, or thermostat feedback to maintain comfortable and energy‑efficient environments. Refrigeration — evaporator/defrost control and compressor protection in household or commercial refrigerators and freezers. Water heaters and washing machines — thermostat feedback and temperature control in tanks and wash cycles to protect components and improve performance. Industrial appliances — temperature monitoring in dryers, dishwashers, ovens and control units where rapid, reliable sensing is required.
