Honeywell 112-102EAJ-B01 Temperature Sensor Guide
The Honeywell 112-102EAJ-B01 temp sensing thermistor is part of the 112 Series, a Honeywell temperature sensing platform built around glass bead NTC thermistors for general-purpose and elevated-temperature applications. This model is commonly evaluated in systems where compact thermal feedback is required and where the designer wants a sensor format known for stable performance across a wide temperature span. The Honeywell 112-102EAJ-B01 temp sensing thermistor is especially relevant for users looking for a 1 kOhm thermistor solution within a proven industrial sensing family.
Technical Profile of the Honeywell 112-102EAJ-B01 Temp Sensing Thermistor
Published distributor listings describe the Honeywell 112-102EAJ-B01 temp sensing thermistor as an NTC thermistor with 1 kOhm nominal resistance and 20 percent tolerance. It is generally referenced as a large bead 112 Series part, and related 112 Series documentation describes these thermistors as hermetically sealed in glass for general-purpose temperature measurement and control. The broader series is also associated with high-temperature capability, typically reaching up to 300 °C, which is one reason these parts remain useful in industrial electronics and thermal monitoring environments.
Where This Honeywell Temp Sensing Thermistor Fits Best
Not every temperature sensor application needs a complex digital module. In many cases, a well-chosen NTC thermistor offers a more efficient and direct path to thermal measurement or compensation. The Honeywell 112-102EAJ-B01 temp sensing thermistor is relevant in designs where sensor size, analog responsiveness, and proven material stability are more important than interface complexity. That includes control circuits, thermal management assemblies, and equipment requiring dependable temperature-dependent resistance behavior.
The 112 Series also makes comparison easier for engineers who need to align resistance values and tolerance classes across related parts.
