Honeywell 135-104LAG-J01 Temperature Sensor Overview
The Honeywell 135-104LAG-J01 temperature sensor is a 100K NTC thermistor developed for applications that require broad thermal coverage and dependable mechanical construction. As part of the Honeywell 135 Series, it is associated with glass-encapsulated axial packaging and a specification profile that suits many industrial and professional sensing tasks. For engineers researching a Honeywell 100k thermistor, this part is a useful reference in both new design and replacement planning.
Understanding the Honeywell 135-104LAG-J01
The Honeywell 135-104LAG-J01 NTC thermistor uses a 100 kOhm nominal resistance at 25°C and offers a known beta characteristic that helps define its temperature response curve. That matters in engineering because the real value of a thermistor is not just its resistance at room temperature, but how predictably that resistance changes as the environment heats up or cools down. In practical terms, this makes the part suitable for monitoring, control, and compensation roles across a range of systems.
Design Benefits and Use Case Relevance
The Honeywell 135-104LAG-J01 temperature sensor is especially relevant where a rugged, easy-to-integrate thermistor is needed. The axial lead structure supports familiar installation practices, while the glass-encapsulated design contributes to durability. Designers may evaluate this part in heating controls, industrial monitoring systems, appliance electronics, laboratory instruments, and environmental sensing assemblies.
Why the 100K Honeywell Thermistor Category Matters
Search demand for 100k NTC thermistor, Honeywell thermistor sensor, industrial temperature sensor, and high temperature thermistor remains strong because many applications still rely on proven analog sensing components. The Honeywell 135-104LAG-J01 temperature sensor remains relevant in that context because it serves real operational needs without unnecessary complexity.
Evaluation Perspective
When professionals compare thermistors, they often look at resistance value, tolerance, beta behavior, package style, and operating range before anything else. The Honeywell 135-104LAG-J01 100K NTC thermistor provides a combination of those core selection factors in a recognizable Honeywell format, which is why it frequently appears in research, sourcing, and maintenance workflows.
