Magnetic Sensors - Switches (Solid State)

Solid state magnetic switches, commonly referred to as AH373-WL-7, offer a number of advantages over traditional electromechanical switches, chiefly in their superior accuracy and precision, as well as their ability to operate in severe conditions.AH373-WL-7 switches are designed to detect the presence of a magnetic field. These switches are equipped with a magnetically sensitive element that generates an electrical output when exposed to an external magnetic field. The switch responds to the application of a specific magnetic field strength and responds in a reliable manner, even after it has been subjected to shock, vibration, and extreme temperatures.The working principle of the AH373-WL-7 switch is fairly simple. As the switch is exposed to a specific level of magnetic field, the magnetically sensitive component inside the switch is disturbed. This disturbance results in a change in the electrical resistance of the materials inside the switch, which can be easily detected through readout. The magnetic field can be related to the output of the switch in a variety of ways, such as detecting a particular field strength, detecting transition between two fields, or detecting a change in the orientation of the magnetic field.The AH373-WL-7 switch can be used in a variety of applications such as door alarms, security systems, light switches, HVAC controls, and other magnetic field detection applications. By using the switch in combination with a microcontroller, more advanced features can be added to the system, such as adjusting the switch’s sensitivity, detecting multiple field strengths, or automatically calibrating the switch based on a preset field strength.One major advantage of this type of switch is that it can be used in areas with extreme and harsh environmental conditions. The switch is also explosion-proof and waterproof, making it ideal for applications in hazardous environments such as marine, mining, and industrial settings.Overall, AH373-WL-7 switches are highly reliable and versatile, making them a great choice for applications where accuracy and precision are of utmost importance. They can be used in a wide range of applications where the detection of magnetic fields is required, and their robustness makes them a great choice for applications in extremely harsh environments.
