Honeywell 112-501BAJ-B01 Temp Sensing Thermistor
The Honeywell 112-501BAJ-B01 temp sensing thermistor is a discrete NTC component built for dependable temperature measurement and control in compact electronic systems. As a Honeywell 112-501BAJ-B01 temperature sensor, it is part of the 112 Series, known for glass bead construction, long-term resistance stability, and strong performance in both general-purpose and technically demanding thermal applications.
Core Characteristics of the Honeywell 112-501BAJ-B01 Temp Sensing Model
This sensor uses a hermetically sealed large glass bead design with adjacent leads. That design matters because it helps isolate the active sensing element from moisture and contamination while supporting repeatable behavior over long operating periods. The Honeywell 112-501BAJ-B01 temp sensing part is associated with a nominal resistance of 500 Ohm at 25°C and a 25/85 beta value of 2772, making it a relevant option when engineers need a lower-resistance NTC thermistor for temperature tracking or compensation.
Like other NTC thermistors, it reduces resistance as temperature rises. That makes it useful in thermal regulation circuits, compensation networks, instrumentation, and embedded sensing designs that depend on predictable thermal response. Because the package is compact and discrete, it can be positioned close to the thermal source, which often improves measurement relevance in tightly packed assemblies.
Application Perspective
The Honeywell 112-501BAJ-B01 temp sensing thermistor is often evaluated for industrial control electronics, custom sensing assemblies, thermal compensation on circuit boards, and monitoring systems where sensor placement and physical size are critical. Its glass-sealed structure also supports use in environments where long-term drift must be controlled more carefully than with lower-grade sensing elements.
Another advantage is versatility. Engineers working across research equipment, process control modules, and specialized electronic assemblies often prefer discrete thermistors because they allow more freedom in circuit tuning and mechanical integration. The Honeywell 112-501BAJ-B01 temperature sensing element fits that approach well by combining compact dimensions with reliable thermal behavior.
