Magnetic Sensors - Switches (Solid State)

Magnetic Sensors - Switches (Solid State) are used to detect changes in magnetic fields, or a magnetic reaction to an external stimulus. The AH173-WL-7-B is a type of Magnetic Sensor - Switch (Solid State), with a wide range of uses and working principles.

This Magnetic Sensor - Switch (Solid State) operates on Hall Effect principles. Hall Effect is a physical phenomenon whereby a voltage difference is created across a conductor when a magnetic field is applied perpendicular to the current carried out by the conductor. This voltage, which is known as the Hall voltage, is fairly linear, and therefore can be used to detect changes in the magnetic field – such as when a magnet is brought close to the conductor, or when an external electric field is applied. In this way, the Magnetic Sensor - Switch (Solid State) is able to convert physical motion, such as coming into contact with a magnet, into electrical signals.

The AH173-WL-7-B also utilizes Reed Switches, which are made of two ferromagnetic reeds, or conductive paths, placed inside a steel tube and connected to electrical terminals. When a magnetic field is applied to the reeds, they move close together and create a contact, allowing an electrical current to flow. When the magnetic field is removed, the reeds separate and the contact is broken, preventing the current.

The AH173-WL-7-B is a small, solid-state switch, which combines both Hall Effect and Reed Switch technologies. This makes it an ideal choice for applications requiring reliable and accurate detection of changes in magnetic fields. The switch contains several parts, including a magnet, a Hall Effect sensor, and the two necessary reed switches. The inner magnet is used to create a strong magnetic field, and the Hall effect sensor monitors changes in that field to detect movement or change in direction or intensity. The Reed Switches, meanwhile, act as electrical contacts that are closed or opened depending on the presence of magnetic fields.

The AH173-WL-7-B has a wide range of potential applications, due to its versatility and small size. It can be used in security systems, robotics, and automatic doors and windows, among many other applications. Additionally, its high sensitivity and long-term reliability make it a particularly suitable choice for applications such as automatic door openers.

In summary, the AH173-WL-7-B is an advanced magnetic sensor-switch (solid state) which utilizes Hall Effect and Reed Switch principles. Its small size, high sensitivity, and long-term reliability make it an ideal choice for a wide variety of applications, including robotics, security systems, and automatic doors and windows.
