Molex NTC Probe Thermistors

Molex NTC Probe Thermistors are designed to provide accurate temperature readings in difficult-to-reach locations. These thermistors feature a flexible design with free end wires that can be soldered directly on the PCB and assembled in a terminal block. These end wires can also be crimped to a terminal and used with connectors to provide multiple design options. The NTC probe thermistors have a glass sleeve that ensures protection against abrasion and mechanical damage. The ring terminal mounting tag enables secure surface mounting and heat detection. These thermistors are available in a variety of beta values, lengths, and temperature ranges for a multitude of diverse applications. Typical applications include vending machines, LED lighting, metal 3D printers, printing machines, medical devices, fire detectors, and heating systems.
