59250-1-S-02-B Datasheet/PDFThe 59250-1-S-02-B belongs to the family of magnetic sensors – position, proximity, speed (modules) which are designed to sense the presence of a metallic target that is close to the sensing device. In the context of magnetic field sensing, the module comprises the sensing device, a magnetic core and a magnetic target. The sensing device senses the position of the magnetic core and in turn provides the relative position of the magnetic target with respect to the sensing device. This is done by sensing the changes in flux intensity between the two parts.
Applications
The 59250-1-S-02-B is intended to be used in wide range of applications which require highly accurate measurements of position, proximity and speed. Some common applications are automation, robotics, security systems, navigation systems, automotive engine monitoring and process control systems. Its main benefits are accuracy and reliability.
Working Principle
The sensing device of the 59250-1-S-02-B is based on the principle of Hall effect. It works on the principle that when a current carrying conductor is placed in a magnetic field, the magnetic flux passing through the conductor gets distorted and hence produces a measurable output voltage which can be measured. This measuring component is called as the Hall Effect sensor. The Hall effect sensor of the 59250-1-S-02-B is made up of an aluminum substrate on which the sensing device is mounted. The sensing device is connected to the target via a wire.
The magnetic core of the device is housed in a cylindrical body which is made up of a ferromagnetic material such as iron or steel. The magnetic core produces a magnetic field around it which is proportional to its current and hence can be accurately calibrated. The relative position of the magnetic core and the target is thus determined by measuring the variation in the magnetic flux between the two.
The change in the flux intensity of the core and target results in an output voltage which is proportional to the change in flux intensity. The output voltage is then fed to an analog to digital converter which in turn provides a digital signal corresponding to the sensed position of the target. This digital signal is then used to control the operation of the target.
The 59250-1-S-02-B is an ideal device for applications where accuracy and reliability are required. It offers high accuracy and a wide dynamic range of measurement which makes it a very reliable magnetic sensing device.
Conclusion
The 59250-1-S-02-B is a magnetic sensor module designed for applications which require precision and reliability. It uses the Hall effect principle to sense the presence of metallic targets close to the sensing device and provides an output voltage proportional to the magnetic flux variation between the sensing device and the target. This device is ideal for applications in automation, robotics, security systems, navigation systems, automotive engine monitoring and process control systems.
