Vishay Intertechnology introduces a new epoxy-coated NTC thermistor with long PEEK-insulated, NiFe leads and a low thermal gradient for fast, high accuracy temperature measurement, sensing, and control in automotive and industrial applications.
The sensor’s conductor wire features the lowest thermal conductivity available on the market. Due to its excellent thermal decoupling, the device enables superior temperature measurement accuracy compared to other conductive wire materials, such as copper, which can deviate by several degrees.
High adhesive strength between the device’s PEEK-insulated lead wires and encapsulating epoxy lacquer Improves reliability in high humidity conditions. Long —75 mm —and flexible radial leads allow for special mounting or assembly requirements.
