Thin-Film Temperature Sensor, High Temperature Type, MJMA
Among all types of our temperature sensors, the thin film temperature sensor provides the fastest response speed, smallest size, lightest weight and thinnest thickness.
In March 2012, Minjie Electronics set up a research project of MJMA thin-film temperature sensors and in April 2015, this type of high temperature sensor was put into mass production and quickly won high praise from many customers.
The successful research of MJMA temperature sensor fills in the gap of thin-film NTC temperature sensor in China and quickly swept the market for its fast response, small size, thin thickness, high reliability, compact structure, concise appearance and bending resistance.
The innovation of the high-temperature thin-film temperature sensor is mainly demonstrated in these following aspects
- This NTC temperature sensor abandons traditional electric cable and implements flexible flat cable to increase the bending resistant capacity of products and make sure it can be used in narrow space. Plus, the length of temperature sensing product can be designed upon request.
- Produced with uniform flexible flat cables, the thin-film sensor overcomes traditional problems like complex structure and low uniformity. The MJMA thin-film temperature sensor provides a wide temperature range (-40 to 260℃), high voltage resistance, small volume, light weight and thin thickness (0.2mm). It's widely used in cellphones, home appliances and aviation.
- High-degree automatic production of MJMA high temperature sensor is realized thanks to its brilliant design and excellent properties. Therefore, it will inevitably replace traditional temperature sensors. Moreover, because the manufacture process is simplified, the reliability, uniformity, precision and sensitivity are further guaranteed.

- The insulation-film covered sensor has a fast response speed, high voltage resistance and accurate temperature measurement.
- With a small size, light weight, compact structure and bending resistance, the thin-film sensor is easy to be automatically installed.
- Abandoning the traditional temperature measuring method of contact sensing, this thin-film type sensor indirectly gets the temperature, with high precision. In addition, by using the thin-film sensor, there is no need to drill a hole on the bottom of appliance for mounting sensor, it makes the clean-up work easy and keep an intact appliance bottom.
- According to the types of thin films, the temperature sensors can be divided into high temperature sensor and low temperature sensor.
- According to the properties of thin film, the temperature sensor can be classified into acid resistant sensor and alkali resistant sensor, able to resolve the fast temperature measuring problem under extreme environments.
Using the thin-film temperature sensor, the appliance bottom is flat and smooth, easy to clean and water scale free.
For commonly-used sensors, the appliance bottom is drilled with holes to install sensor. The hole surrounding part is difficult is clean and easy to hide water scale.
