Magnetic Sensors - Switches (Solid State)

Magnetic sensors, also called magnetic reed switches, are electronic components that detect changes in magnetic fields. Magnetic sensors are widely used in many applications, such as automotive, aerospace, and medical applications. The S-5742NBL1B-Y3N2U magnetic sensor is a commonly used precision magnetic switch used in applications requiring very small size, fast response time, and reliable performance.

Application Field

The S-5742NBL1B-Y3N2U magnetic switch can be applied in various environments, such as automotive, test and measurement, aerospace, and medical applications, where reliable precision measurements are required. It is designed to detect small and weak magnetic fields, making it suitable for applications that require quick and precise measurement of magnetic fields. For example, in automotive applications, it can be used to detect door or window opening and closing; in aerospace applications, it can be used to detect movement of an aircraft’s wings; in medical applications, it can be used to detect the presence or absence of a magnetic field in a patient’s body.

Working Principle

The S-5742NBL1B-Y3N2U magnetic sensor consists of a two-part package, the armature and magnet. The armature contains two soft iron plates which act as sensing elements, and a permanent magnet. The two sensing elements are mounted in opposite directions, and are connected to a voltage supply line. When the magnetic field strength in the vicinity of the magnet exceeds a certain threshold, a voltage difference is created between the two sensing elements. This voltage difference triggers a switch, which then activates the electrical or electronic device connected to the sensor. When the magnetic field in the vicinity of the sensor is weak or nonexistent, the voltage across the two sensing elements will be equal, and the switch will remain open, thus preventing the device from being activated.The S-5742NBL1B-Y3N2U magnetic sensor can detect both DC and AC magnetic fields, making it suitable for many different applications. In addition, it is able to operate reliably and accurately in temperatures ranging from -20℃ to +85℃, offering excellent performance under extreme temperature conditions.

Conclusion

The S-5742NBL1B-Y3N2U magnetic switch is a precision magnetic switch designed to detect changes in magnetic fields in many applications, including automotive, aerospace, and medical applications. It is capable of detecting both DC and AC magnetic fields, and operates reliably and accurately in extreme temperatures. It is robust, reliable, and precise, making it an ideal choice for applications that require quick and reliable measurements of magnetic fields.
