AH337-PL-B Magnetic Sensors - Switches (Solid State)

Magnetic Sensors - Switches (Solid State) are used in a variety of applications where either a magnetic field or a change in the magnetic field is detected. The AH337-PL-B is one such device that provides both a switch and a proximity sensor in a single package.

Applications

The AH337-PL-B is typically used in applications where a switch is opened or closed by sensing either a magnetic field, or if the strength of a magnetic field is above or below a particular value. This type of sensor would be ideal for applications that require accurate and reliable position sensing, such as a door opening and closing system. The AH337-PL-B is also well-suited for safety and security applications, such as an alarm system or a fence line detector in a security system. Additionally, the AH337-PL-B can be used in robotic applications, such as a robotic arm that is activated by presence of a magnetic field.

Working Principle

The AH337-PL-B is a switch and a proximity sensor in one, offering both a Real Time Sensor (RTS) and a magnetic field detection sensor in one package. This dual capability allows the AH337-PL-B to be used for both magnetic field detection and switch operation. The Real Time Sensor (RTS) is powered by a 12V DC power supply and provides an output signal that is proportional to the strength of the magnetic field applied to it. When the magnetic field strength reaches a certain threshold, the RTS will trigger an output change, either opening or closing the switch. The RTS is also temperature compensated, allowing the AH337-PL-B to provide accurate operation when conditions vary. The magnetic field detection sensing is also powered by a 12V DC power supply and detects changes in the strength or direction of the magnetic field. When a sufficient change is detected in either the strength or direction of the magnetic field, the AH337-PL-B will trigger a change in the output, again either opening or closing the switch. This allows the AH337-PL-B to detect not only the presence of a magnetic field, but also changes in the magnetic field. The AH337-PL-B is a versatile device that can be used in a variety of applications. With its ability to detect both the presence and changes in magnetic fields, the AH337-PL-B is ideal for applications involving both switch operation and magnetic field sensing. Additionally, the RTS temperature compensation feature allows for reliable operation over a broad range of temperatures.

Conclusion

The AH337-PL-B is a highly versatile device that can be used in a wide variety of applications. With its ability to detect both the presence and changes in the magnetic field, the AH337-PL-B is ideal for both switch operation and magnetic field sensing. Furthermore, the RTS temperature compensation feature makes the AH337-PL-B suitable for operation over a broad temperature range.
