Honeywell 111-202CAK-901 Temp Sensing Thermistor Explained
An Introduction to the Honeywell 111-202CAK-901 Temperature Sensing Thermistor
The Honeywell 111-202CAK-901 temp sensing thermistor is an NTC thermistor in Honeywell’s 111 Series, a family recognized for miniature glass bead construction and broad temperature capability. This Honeywell 111-202CAK-901 temperature sensing thermistor is designed for applications that benefit from compact dimensions, through-hole mounting, and dependable resistance change across a wide thermal range. It is especially relevant in assemblies where the designer needs a small sensor that can be placed close to the temperature source.
At 25°C, the Honeywell 111-202CAK-901 temp sensing thermistor has a nominal resistance of 2,000 Ohm. Available technical references also identify the part as a bead-style NTC thermistor with through-hole mounting, bulk packaging, and an operating range from -60°C to 300°C. The listed resistance tolerance is ±25%, which is an important specification for designers building compensation or temperature-monitoring circuits around defined nominal resistance behavior.
Main Features of the Honeywell 111-202CAK-901 Temp Sensing Component
The appeal of the Honeywell 111-202CAK-901 temperature sensing thermistor comes from the same traits that define the 111 Series overall: a compact glass bead form factor, fast thermal response, and suitability for low heat capacity applications. In real-world use, these properties help the sensor react to temperature changes quickly without requiring the larger body or heavier thermal mass associated with packaged probes.
Because it is a Honeywell 111-202CAK-901 thermistor rather than a complete housing-based assembly, it is well suited for designs that need flexibility in placement. Compact instrumentation, laboratory systems, thermal compensation circuits, and small embedded sensing layouts are all examples of environments where this type of NTC component may be considered.
Why Engineers Search for Honeywell 111-202CAK-901 Temp Sensing Thermistor Data
Engineers and technical procurement teams looking up the 111-202CAK-901 temperature sensor often want confirmation of resistance value, package style, operating range, and series family behavior. Those details matter because sensor selection is rarely based on part number alone. The Honeywell 111-202CAK-901 temp sensing thermistor stands out as a compact 2 kOhm option within a miniature high-temperature-capable family.
Its small bead construction also makes it easier to integrate into assemblies where response speed and tight placement are priorities. For more information about Honeywell, you can review additional product context here.
