They are mainly composed of the following parts: NTC thermistor, injection molded parts, high temperature film, wires, and connectors. Temperature sensors used in office automation, such as printers and copiers, must be resistant to high temperatures and have a fast response speed. Therefore, thermistors are basically glass-encapsulated (axial or radial); injection molded parts must be opened and used through the mold. Injection molded parts and steel sheets are integrally formed; high-temperature films need to withstand temperatures of 200°C or above, so Teflon films and polyimide films are usually used; as for wires, we usually choose high-temperature-resistant wires, such as PE wires And Teflon wire, both wires must be single wires, not parallel wires; and the connectors are usually imported brands, such as JST, AMP, etc.
The office automation NTC temperature sensor is applied to the roller of the fixing device of the printer or copier. It uses a high-temperature single-ended glass-sealed thermistor. The injection molded part and the steel sheet are formed integrally through the mold. The high-temperature film is selected, and the wires are connected and connected. Device. It has the characteristics of high precision, high sensitivity and high temperature resistance.
