Magnetic Sensors are devices that measure the strength and/or direction of a magnetic field. One type of magnetic sensor is a Solid State switch, such as the SS413A.

The SS413A senses magnetic fields using a Hall-effect semiconductor. It is designed to be sensitive to changes in the magnetic field, rather than absolute field strength. When the magnetic field is changed close to the device, the Hall-effect switch changes state. This allows the SS413A to be used to detect the presence or absence of a magnetic field.

The SS413A is typically used in automotive and industrial applications where reliable, non-contact switches are required. In automotive applications, the SS413A can be used to sense the position of a wheel, or the presence of a ferrous metal target. It is also used in industrial applications to detect the position of shafts or rotating parts.

In operation, the SS413A has three output states: OFF, ON and HI-Z (high impedance). The OFF state is when the magnetic field is absent, the ON state is when the magnetic field is present, and the HI-Z state is when the device is being interrogated. The HI-Z state is useful for checking the status of the switch, or for refreshing the output state after a long time.

The SS413A also offers a variety of operating characteristics. It can be powered from 3.3V to 5V, has a switching frequency range between 10kHz and 400kHz, and can handle up to 1A of continuous current. It has an operating temperature range of -40°C to +125°C, and can be used in a wide variety of applications.

The SS413A is an ideal solution for applications requiring reliable, non-contact switches. It is simple to use, provides reliable performance in harsh environments, and can be used in a variety of automotive and industrial applications.
