Honeywell 112-103FAJ-B01 Temp Sensing Details
The Honeywell 112-103FAJ-B01 Temp Sensing thermistor is part of the Honeywell 112 Series, a well-known family of discrete glass-bead temperature sensing components. This model is typically discussed in design environments where compact dimensions, thermal stability, and dependable resistance behavior are more important than a large packaged housing. For engineers working on thermal monitoring, control loops, and compensation circuits, the Honeywell 112-103FAJ-B01 temperature sensor thermistor is a familiar configuration.
Product Positioning in the 112 Series
Honeywell’s 112 Series is associated with hermetically sealed glass construction and use in general-purpose temperature measurement and control applications. The Honeywell 112-103FAJ-B01 Temp Sensing model is specifically identified as a large glass bead version with adjacent leads. That structure is useful in projects where a discrete sensor must fit into a tightly controlled thermal path without requiring a more complex packaged assembly.

Where It Fits Best
The Honeywell 112-103FAJ-B01 Temp Sensing thermistor suits design teams that need analog temperature feedback in control electronics, industrial instrumentation, and equipment where space and thermal responsiveness both matter. Because it is a discrete bead device, it can often be positioned close to the thermal event being measured. That can improve measurement relevance compared with placing a larger sensor farther away from the heat source.
Another reason this part family remains relevant is design simplicity. A Honeywell 112-103FAJ-B01 temperature sensing thermistor can be integrated into resistor networks, bridge circuits, or conditioning stages without adding unnecessary packaging overhead. For many engineers, that translates into efficient PCB integration and a cleaner thermal measurement strategy.
Why Engineers Still Search for This Part
Search interest around terms such as Honeywell thermistor, NTC thermistor 10k, temperature sensing thermistor, and glass bead thermistor remains strong because these parts continue to support maintenance, redesign, and replacement projects. The Honeywell 112-103FAJ-B01 Temp Sensing model is especially relevant when a project calls for a known Honeywell format with established electrical behavior.
