Honeywell 112-403JAH-H01 Temp Sensing Details
The Honeywell 112-403JAH-H01 temp sensing thermistor is designed for engineers and technical buyers who need a stable NTC sensing element for thermal measurement and control. As a Honeywell 112-403JAH-H01 temperature sensor, it combines a compact glass bead structure with the reliability expected from the 112 Series. This makes it relevant for projects that require durable thermal performance without moving to a larger probe-style format.
Technical Character of the Honeywell 112-403JAH-H01 Temp Sensing Part
This model is part of Honeywell’s well-established glass bead thermistor range. The sensor is hermetically sealed, which helps maintain performance in environments where humidity, contamination, or repeated thermal cycling can challenge ordinary sensing elements. In engineering terms, that means the Honeywell 112-403JAH-H01 temp sensing component supports stable resistance behavior and dependable repeatability in long-service applications.
The part is associated with a nominal resistance of 40 kOhm at 25°C and the standard NTC principle, where resistance drops as temperature rises. That response curve makes it useful in analog sensing circuits, compensation networks, thermal balancing designs, and monitoring systems that need predictable response behavior. In many practical applications, a component like this is selected not only for its measurement capability, but also for its resistance stability over time.
Where This Honeywell Temperature Sensor Fits Best
The Honeywell 112-403JAH-H01 temp sensing thermistor is a practical choice for instrumentation, industrial electronics, control modules, HVAC-related electronics, and advanced custom assemblies. It can also suit environments where compact board-level thermal sensing is needed but environmental protection remains a design priority. Because the sensor is physically small, it can be placed close to heat-sensitive zones, supporting more representative temperature readings inside dense systems.
In design workflows, the value of a discrete thermistor often comes from flexibility. Engineers can tune the surrounding circuit, housing, or mounting approach based on application needs. That gives the Honeywell 112-403JAH-H01 temperature sensing component an advantage in specialized builds where standard probe geometries may not be ideal.
FAQ
What kind of output does the Honeywell 112-403JAH-H01 provide?
It is a passive NTC thermistor, so it does not generate an amplified signal. Instead, it changes resistance in response to temperature, and that resistance is measured by the host circuit.
Why do engineers choose a 40 kOhm thermistor?
A 40 kOhm thermistor can be useful in designs where signal conditioning, divider networks, and temperature sensitivity need to be balanced carefully for the target electronics.
Is the Honeywell 112-403JAH-H01 suitable for harsh environments?
Its hermetically sealed glass bead construction helps support use in more demanding environments than many unsealed alternatives, especially where moisture resistance and stability matter.
What applications benefit most from this part?
Measurement systems, industrial controls, compact electronics, and thermal compensation networks are all common scenarios where this kind of Honeywell temp sensing element can be valuable.
