Honeywell 120-104KAJ-Q01 Temperature Sensor Overview
The Honeywell 120-104KAJ-Q01 temperature sensor is an NTC thermistor intended for applications that require high nominal resistance, compact packaging, and durable thermal sensing performance. Engineers typically look at this model when they need a Honeywell 120-104KAJ-Q01 temperature sensor that can fit into a broader industrial or instrumentation design without sacrificing ruggedness. As part of Honeywell’s thermistor portfolio, the part is associated with glass-probe construction and a wide operating range that supports more demanding environments.
Key Technical Details of the Honeywell 120-104KAJ-Q01
The Honeywell 120-104KAJ-Q01 is commonly listed as a 100k Ohm NTC thermistor with ±20% resistance tolerance. Distributor technical listings also identify it as a glass cylindrical probe with free-hanging mounting, a wide operating temperature range of -60°C to 300°C, and a thermistor constant noted as 3442K in one current distributor attribute listing. Mouser additionally describes the model with Dumet lead construction and a 1.5 mm probe dimension in its product description.
Why a 100k NTC Thermistor Matters
In many electronic and industrial measurement systems, a 100k thermistor is selected because it provides a particular resistance profile suitable for sensing networks, compensation circuits, or monitoring architectures. The Honeywell 120-104KAJ-Q01 temperature sensor stands out because it pairs that electrical identity with a rugged physical package rather than a fragile or minimally protected sensing element.
That difference matters in real equipment. Temperature sensors are rarely chosen by resistance value alone. Designers also care about packaging integrity, mounting approach, durability, and how the part behaves under repeated thermal exposure. This is where Honeywell’s glass-probe thermistor format becomes especially relevant.
Typical Application Perspective
The Honeywell 120-104KAJ-Q01 temperature sensor can be considered for industrial controls, instrumentation, research systems, and embedded equipment where compact thermal sensing is required across a wide operating range. It is particularly useful when a design calls for a higher-resistance NTC thermistor in a durable package that can tolerate challenging installation conditions.

FAQ
What is the resistance value of the Honeywell 120-104KAJ-Q01?
The Honeywell 120-104KAJ-Q01 is commonly listed as a 100k Ohm NTC thermistor. That nominal value makes it relevant for temperature measurement circuits designed around higher thermistor resistance profiles.
What kind of package does the Honeywell 120-104KAJ-Q01 temperature sensor use?
This model is described as a cylindrical glass probe. That packaging style is important because it supports durability, compact installation, and a more rugged sensing structure than many simpler thermistor forms.
How wide is the operating temperature range of the Honeywell 120-104KAJ-Q01?
Current distributor data lists the operating temperature range as -60°C to 300°C. This broad range is one of the reasons the sensor is relevant for more technically demanding thermal environments.
Why would an engineer choose the Honeywell 120-104KAJ-Q01 temperature sensor?
An engineer may choose it when a project requires a 100k NTC thermistor with compact size, durable glass-probe construction, and a wide thermal operating window. It is a practical option when both electrical characteristics and mechanical packaging matter.
Is the Honeywell 120-104KAJ-Q01 suitable for industrial temperature sensing?
Yes, it is a strong candidate for industrial temperature sensing discussions because of its high resistance value, rugged physical format, and wide operating range. Selection should always be matched to the exact circuit and environmental requirements, but the model is clearly positioned as a serious technical sensing component rather than a casual general-purpose part.
