Magnetic sensors, also known as switches, are used to detect changes in a magnetic field. Examples of these sensors include Hall-effect sensors and magnetoresistive sensors. The AH1809-P-A is a Solid State magnetic sensor that can detect a wide variety of magnetic fields. This article will explain the application field and working principle of the AH1809-P-A.

The AH1809-P-A is a solid state, single-element Hall-effect switch designed for magnetically-operated control systems. It has a built-in Schmitt trigger for superior performance and more reliable switching. The switch is powered by a 3.3 VDC voltage, and it is capable of detecting magnetic fields ranging from -50 to +50 gauss. The switch also features a low-power consumption of 3mA and a low quiescent current of 1 to 2µA.

The AH1809-P-A is commonly used for magnetic proximity sensing applications. These types of applications require a device that can detect the presence of a magnet and trigger an action. This could be a switch to open and close a circuit, or it could be a signal to activate a device or system.

The AH1809-P-A is also used in the automotive industry to monitor and maintain an accurate operating temperature inside of a vehicle’s engine compartment. The switch will detect a magnetic field generated by a thermocouple that is placed in the engine bay. When the temperature fluctuates beyond a certain range, the switch will trigger a signal, which in turn activates a cooling system.

The working principle of the AH1809-P-A is based on a Hall effect. The Hall effect is a physical phenomenon that can be observed when a voltage is applied across a current-carrying conductor in the presence of a magnetic field. In the case of the AH1809-P-A, when a magnetic field is detected, the voltage across the conductor changes and triggers the switch.

The AH1809-P-A has a wide range of applications in industries such as automotive, security, military, and consumer electronics. The switch is also extremely flexible, allowing for multiple configurations and settings. With its superior performance and low power consumption, the AH1809-P-A is a reliable and cost-effective solution for magnetic proximity sensing applications.

In summary, the AH1809-P-A is a reliable and cost-effective solid state magnetic sensor with a wide range of applications. The sensor is commonly used for magnetic proximity sensing applications, and it is based on the Hall effect phenomenon. The sensor is highly flexible and consumes very little power, making it an ideal choice for a variety of applications.
