Magnetic Sensors
A magnetic sensor, also known as a magnetometer or magnetic field sensor, is a device that is used to measure and detect magnetic fields. It can be used in a variety of applications, including navigation, robotics, and industrial automation.
There are several types of magnetic sensors available, each with its own unique properties and applications. Some common examples include Hall effect sensors, reed switches, and proximity sensors.
1. Hall effect sensor: This type of magnetic sensor is based on the Hall effect, which is the creation of a voltage difference across a conductor when it is subjected to a magnetic field perpendicular to the direction of current flow. Hall effect sensors are commonly used to measure magnetic fields in electronic devices.
2. Reed switch: A reed switch is a small, magnetically operated electrical switch. It consists of two thin metal blades that are hermetically sealed in a glass envelope. When a magnet is brought near the switch, the blades are drawn together, closing the circuit.
3. Proximity sensor: Proximity sensors use the concept of magnetic field disturbance to detect the presence of an object. They can be used to detect the presence or absence of metal objects in a wide range of applications.
Magnetic sensors can be classified into two main types: magnetoresistive sensors and flux gate or coil sensors.
1. Magnetoresistive sensors: These sensors measure changes in electrical resistance as a function of the applied or ambient magnetic field. They are commonly used in automotive applications, such as rotation speed sensing and position sensing.
2. Flux gate or coil sensors: These sensors measure differences in the magnetic field at the ends of a vertical rod and then plot this information on a grid. They are often used in geophysical applications, such as measuring the Earth’s magnetic field.

A magnetic sensor, also known as a magnetometer or magnetic field sensor, is a device that is used to measure and detect magnetic fields. It can be used in a variety of applications, including navigation, robotics, and industrial automation.
Some examples of magnetic sensors include reed switches, Hall effect sensors, and proximity sensors. These sensors are used to measure and detect magnetic fields in various applications.
The two main types of magnetic field sensors are magnetoresistive sensors and flux gate or coil sensors. Magnetoresistive sensors measure changes in electrical resistance as a function of the applied or ambient magnetic field, while flux gate or coil sensors measure differences in the magnetic field at the ends of a vertical rod and then plot this information on a grid.
Electromagnetic sensors are non-destructive evaluation technologies that are widely used in health monitoring and damage detection for infrastructures. These sensors use electromagnetic energy to detect and measure various properties of materials without physical contact.
An inductive proximity sensor is a sensing device that detects metal targets using electromagnetic energy and without contact. The sensing range of an inductive proximity sensor changes based on the type of metal being detected.
Current sensors are devices used to measure the flow of current in an electric circuit. They can also be referred to as current transducers or current sense transformers.
Inductive sensors are used to detect only metal objects. Capacitive sensors are used to detect both metallic and non-metallic objects.
Magnetic proximity sensors are non-contact proximity devices that are used to detect magnetic objects, such as permanent magnets. They sense the presence of a magnetic object, commonly referred to as the target.
There are various types of sensors, including temperature sensors, pressure sensors, proximity sensors, motion sensors, humidity sensors, and many more. Each type of sensor is designed to measure a specific physical property or detect a specific phenomenon.
