Honeywell 112-202EAJ-B01 Temp Sensing Details
The Honeywell 112-202EAJ-B01 Temp Sensing thermistor is a discrete NTC sensor designed for engineers who need compact and dependable thermal measurement. In temperature-sensitive systems, the ability to monitor localized heat accurately can affect control logic, safety margins, and long-term performance. The Honeywell 112-202EAJ-B01 temperature sensing thermistor is especially relevant in applications where a small glass-bead structure is preferred over larger packaged sensors.
Position in the Honeywell 112 Series
This model is part of the Honeywell 112 Series, a line of glass-bead thermistors used for measurement and control. The Honeywell 112-202EAJ-B01 Temp Sensing variant is identified as a large glass bead with adjacent leads. That matters because sensor geometry influences thermal coupling, placement options, and response behavior in real assemblies.
