Specialized Sensors play an important role in our daily life. They act as a bridge between the physical world and digital world. Among them, BE-A301 is one of the most important sensors. This article will discuss its application field and working principle.

BE-A301 is a specialized tactile capacitive sensor. It can detect the surface shape, texture, and pressure, thus gaining a nice performance in harsh environments. It applies to a variety of products to detect the size, shape and pressure of object, such as machinery control sensors, high-end medical disposables and so on.

The working principle of BE-A301 is based on the capacitance change of the human body induced by electric field changes. It utilizes sensing mats to detect signal changes. The sensing mats contain multiple electrode fingers. Every finger is independent, so there are multiple independent sensing point. These sensing points can sense the physical pressing location, pressure value, and the speed of hand slipping.

The way it works can be described with three parts. Firstly, the electrode fingers will collect electrical signal form user’s body when they contact with user’s body. Secondly, the collected signal will be processed by Circuit. Thirdly, the processed signal will be output the corresponding data. The data output will inform the user about the size, shape and pressure of the object.

BE-A301 applying capacitive technology can measure the surface shape, size, pressure and texture accurately and proactively. This will make sure the accuracy and response of control system. And this sensor can react conveniently even in high moisture environments, which is widely used in automatic control, sensing, healthcare and other industries.

In conclusion, this article introduced BE-A301’s application field and working principle. This sensor has excellent performance in harsh environments and wide applications including automatic control, sensing, healthcare and so on. It will play an increasingly important role in our daily life.
