Honeywell 128-253XTW-Q01 NTC Thermistor Probe Overview
The Honeywell 128-253XTW-Q01 NTC thermistor probe is a precision temperature sensing component in the Honeywell 128 Series. Public distributor product data identifies it as a 25 kΩ NTC thermistor probe with ±1% resistance tolerance, an operating range of -60°C to 300°C, and a 1.25 inch (31.80 mm) lead wire length. Those specifications make it a strong fit for accurate thermal sensing in engineered systems.
As a Honeywell 128-253XTW-Q01 temperature sensor, it combines the practical benefits of a probe assembly with the predictable electrical behavior of a precision NTC thermistor. That balance matters in applications where the sensor must not only read temperature correctly, but also integrate cleanly into a controlled mechanical design.

Why the Honeywell 128-253XTW-Q01 Is Important
The Honeywell 128-253XTW-Q01 probe thermistor is useful for designers who need a more tightly controlled nominal resistance value. The ±1% tolerance helps support better consistency in designs where calibration, resistance tracking, or circuit accuracy are key requirements. In many sensor-driven systems, tighter component tolerance can simplify compensation and improve confidence in the final reading.
Its wide operating range is another major advantage. A sensor that can work from -60°C to 300°C is relevant to more than ordinary room-temperature monitoring. It can support demanding industrial, test, and specialty thermal applications where the environment may shift sharply across operating conditions.
Typical Uses
The Honeywell 128-253XTW-Q01 NTC thermistor probe may be considered for industrial equipment, thermal management assemblies, laboratory instrumentation, custom control hardware, and engineered sensing systems that require a 25 kΩ probe with strong tolerance characteristics.
