Magnetic sensors and switches are a type of sensing or controlling devices that measure and/or activate a response to magnetic fields. The AH1808-P-B is an example of such a sensing switch, which is designed to detect the presence of a magnetic field and initiate a switching action. This article will explain the application field and working principle of the AH1808-P-B.

Application Field

The AH1808-P-B magnetic sensor switch can be used in a variety of application fields that require a detection or response to a magnetic field. For example, the switch can be used in security systems where the presence of a magnetic field would indicate an alert or alarm. The switch can also be used in motor control systems to detect the presence of a magnetic field and activate a motor or other device. Finally, the switch can be used in sensing systems where the presence or absence of a magnetic field can be used to determine the position of an object or activate a response.

Working Principle

The AH1808-P-B magnetic sensor switch works on the principle of magnetic field measurement. The switch consists of a sensor assembly and a switching element. The sensor assembly consists of a sensing core which is sensitive to the presence of a magnetic field. When a magnetic field is detected, the core creates an electrical signal which is sent to the switching element. The signal instructs the switching element to open or close, activating or deactivating the switch.

The switching element is typically an electromechanical relay or a solid-state switch that is connected to the sensing core. When a magnetic field is detected, the sensor assembly sends a signal to the switching element, which will then close or open depending on the signal. This will either activate or deactivate the switch, depending on its design.

The AH1808-P-B magnetic sensor switch is designed to be sensitive to low magnetic fields, for example those produced by magnets located at distances of up to 10 cm from the switch. The sensitivity of the switch can be adjusted using an on-board potentiometer, allowing it to be tuned to different levels of magnetic fields. Additionally, the switch has protection features to prevent damage from reversed voltage, overvoltage, or overcurrent.

Conclusion

The AH1808-P-B is a magnetic sensor switch designed to detect the presence or absence of a magnetic field and initiate a switching action. The switch can be used in a variety of application fields, including security systems, motor control systems, and sensing systems. The switch is sensitive to low magnetic fields and can be tuned to different levels using a potentiometer. With its protection features, the AH1808-P-B is a reliable and accurate switch for magnetic field detection.
