Magnetic sensors, commonly known as magnetic switches, are contactless monitoring devices that detect the presence of a magnetic field. The presence of magnetic fields not only interrupts conventional mechanical switches, but can also be used to monitor or measure position, speed, or pressure. Models like AH1803-WG-7 are solid-state switches, meaning they use optical or electronic components instead of mechanical contacts. This makes them more reliable and durable.

The AH1803-WG-7 is a digital Hall-effect sensor designed with an on-chip temperature compensation amplifier. Inside the device, a Hall-effect element detects any magnetic field changes on its surface and determines whether to output a high logic level or a low logic level. The circuit is optimized to reject any current or irrelevant external noise. And it has solid protection and would working reliably under a wide temperature range.

The AH1803-WG-7 works in two directions, meaning it can detect a positive or negative magnetic field. It offers both digital and analog output, which can be easily monitored on an oscilloscope. It also has a high current capacity of up to 25mA and a wide trigger voltage range of 0 to 5V.

The AH1803-WG-7 is used in a variety of applications including automotive, aerospace, and instrumentation systems. It can detect rotation, angular position, linear position, and speed by monitoring a permanent magnet or an electromagnet. Its accuracy is further improved by the on-chip temperature compensation, allowing the sensor to deliver reliable results. In addition, the AH1803-WG-7 is also used in anti-theft systems where it is triggered by a key or transmitter to detect the presence or absence of the corresponding magnetic field.

One of the advantages of the AH1803-WG-7 is that it is non-contact type. This means it can work even without any physical contact with the vehicle or equipment. It can also protect the system from shock and vibration by detecting changes in the magnetic field rather than physical contact.

In conclusion, the AH1803-WG-7 digital Hall-effect sensor is a solid-state switch which provides reliable and durable performance. It can be used in a variety of applications such as automotive and aerospace, and its non-contact nature means it is well-suited for use in harsh environments. It features improved accuracy and temperature compensation, as well as a high current capacity and wide trigger voltage range. The AH1803-WG-7 is an ideal choice for reliable and accurate magnetic sensing applications.
