Epoxy Coated Ntc Thermistor Temperature Sensor 50K 3950
Epoxy Coated: The thermistor is encapsulated in an epoxy resin, which provides protection against moisture, mechanical damage, and environmental factors. This coating makes the sensor durable and suitable for various applications where exposure to harsh conditions might occur.
NTC (Negative Temperature Coefficient): Indicates that the resistance of the thermistor decreases as the temperature increases. NTC thermistors are commonly used for precise temperature measurements because of their predictable response to temperature changes.
50K: Refers to the resistance of the thermistor at 25°C, which is 50,000 ohms (50KΩ). This value is higher than standard 10K thermistors, meaning the sensor is particularly suited for applications where higher resistance at room temperature is desired.
3950: This is the Beta (β) value, a constant that characterizes the relationship between the thermistor's resistance and temperature. The 3950 value typically defines the temperature range between 25°C and 85°C, ensuring the sensor provides accurate readings across this span.
