Honeywell 112-102EAD-H01 Temperature Sensor Overview
The Honeywell 112-102EAD-H01 temp sensing thermistor is part of the Honeywell 112 Series, a product family recognized for compact NTC thermistor designs intended for dependable temperature measurement and control. This model is especially relevant in applications where a small sensor body, free-hanging installation, and broad operating temperature capability are needed. The Honeywell 112-102EAD-H01 temp sensing thermistor is often discussed in the context of industrial temperature monitoring, electronic control systems, thermal compensation, and general-purpose sensing tasks where response stability matters.
Technical Characteristics of the Honeywell 112-102EAD-H01 Temp Sensing Thermistor
Published product listings describe the Honeywell 112-102EAD-H01 temp sensing thermistor as an NTC bead thermistor in the 112 Series with 1 kOhm resistance, free-hanging mounting, and an operating temperature range from approximately -60 °C to 300 °C. Distributor data also lists a resistance tolerance of 2 percent and identifies the device as a large bead thermistor. Broader Honeywell 112 Series descriptions emphasize hermetically sealed glass construction and suitability for low-cost, general-purpose temperature measurement and control applications, with strong thermal stability at elevated temperatures.
Why This Honeywell Temperature Sensor Remains Relevant
NTC thermistors remain widely used because they provide a practical balance of sensitivity, size, and integration simplicity. In the case of the Honeywell 112-102EAD-H01 temp sensing thermistor, the wide operating range and glass bead style make it attractive for users looking at durable temperature sensor solutions rather than disposable low-performance sensing elements. This type of sensor can be particularly valuable in control assemblies where compact packaging and consistent thermal behavior are both priorities.
It also benefits from the clarity of the Honeywell 112 Series platform, which helps engineers compare resistance values, tolerance options, and lead formats without moving outside the same sensor family. For more about Honeywell, the 112 Series is a strong reference point for understanding glass bead thermistor design in industrial sensing.
FAQ
What type of sensor is the Honeywell 112-102EAD-H01?
It is an NTC bead thermistor in the Honeywell 112 Series. NTC means the resistance decreases as temperature rises, which is why these sensors are widely used for temperature measurement and compensation.
What is the nominal resistance of the Honeywell 112-102EAD-H01 temp sensing thermistor?
Published listings identify it as a 1 kOhm thermistor. That nominal resistance is a key specification when matching the sensor to a measurement circuit.
Why is glass bead construction important?
Glass bead construction can support stability, durability, and high-temperature suitability. It helps protect the sensing element in environments where smaller unsealed alternatives may not perform as reliably.
What should engineers verify before choosing this thermistor?
They should confirm resistance value, tolerance, lead arrangement, and how the free-hanging mounting approach fits the application. In temperature sensing, integration method often influences real-world accuracy as much as the sensor itself.
