Magnetic sensors are devices used to detect and measure magnetic fields. They are often used in security, control, and data acquisition applications. The D40B-3E5C is a type of magnetic sensor specifically designed for position, proximity, speed, and other related sensing applications.

The D40B-3E5C’s primary function is to detect the presence of a magnetic field within a specific range of frequency. It is composed of two identical sensing elements, each containing an inductive wire loop and parasitic capacitance. The two sensing elements share a single terminal and are connected internally in a very specific way. This particular design of the D40B-3E5C allows for a much greater range of signal detection.

The D40B-3E5C is typically used in applications such as door and window sensors, motion sensors, and position sensors. In the context of door and window sensors, the D40B-3E5C functions as a door or window entry sensor, detecting the presence or absence of a magnetic field when the door or window is opened or closed. In motion sensor applications, the D40B-3E5C detects the presence of a magnetic field when a person passes through a particular area. And in position sensing, the D40B-3E5C is used to monitor the movement or orientation of a particular object.

In terms of working principle, the D40B-3E5C operates on the principle of magnetoresistance. When exposed to a magnetic field, the two sensing elements of the device will measure a resistance within the signal loop. This resistance is proportional to the strength of the magnetic field. When the resistance becomes unbalanced, the D40B-3E5C will detect a change in the strength of the magnetic field. This change is then read by the output circuit and can be used to detect the presence, absence, or orientation of an object.

The D40B-3E5C is a highly accurate and reliable device, making it ideal for applications where precise measurement and control are required. It is also highly durable, with a long service life and a low tolerance of error. Furthermore, the D40B-3E5C is relatively low-cost, making it suitable for a variety of commercial and industrial applications.

In summary, the D40B-3E5C is a type of magnetic sensor specifically designed for position, proximity, speed, and other related sensing applications. It is commonly used in door and window sensors, motion sensors, and position sensors. The working principle of the D40B-3E5C is based on magnetoresistance, wherein the two sensing elements measure a resistance that is proportional to the strength of the magnetic field. The device is highly accurate and reliable, with a long service life and a low tolerance of error. Furthermore, it is relatively low-cost, making it suitable for a variety of commercial and industrial applications.
