Magnetic Sensors - Switches (Solid State) encompass a wide variety of components that rely on the principles of magnetism to complete a circuit and detect changes in the surroundings. The US2881EUA-AAA-000-SP is one such device, specifically designed to sense changes in magnetic fields. Its working principle is two-fold; it reacts to both the absolute field strength, and changes in field direction. This makes it ideal for tasks such as the detection of small, narrow-width objects.

In common with other types of magnetic sensor-switches, the US2881EUA-AAA-000-SP is highly sensitive to magnetic flux range and switching characteristics, making it one of the most reliable of its kind. When a change in field strength is detected, it will affect the components of the device and cause a reaction. This can be used to turn on a device or cause a signal change. It relies on the switching effects of a magnetic field, depending on the strength of the external field.

The actual components of the sensor are two very small coils which detect the magnetic field, and convert it into electrical signals. The first coil is called the excitation coil, and it is used to send an electrical current into the field, creating a pulse that is picked up by the second coil. This ‘pick up’ coil is connected directly to the output of the device. It is responsible for increasing or decreasing the signal output of an electronic circuit, usually a form of digital logic.

One very useful application for the US2881EUA-AAA-000-SP is in automotive systems, where it can be used to detect small, narrow-width objects on the road and activate an appropriate response. The sensor is sensitive enough to accurately detect objects even when the field is relatively weak. This makes it ideal for detecting objects that can’t be seen with other sensors. The device can also be used to detect changes in magnetic fields in industrial manufacturing processes.

In summary, the US2881EUA-AAA-000-SP is a magnetic sensor-switch that makes use of two small coils to detect changes in magnetic fields. It is sensitive to a wide range of flux and switching characteristics, and is ideal for detecting small, narrow-width objects. It is most suited to applications such as those found in automotive systems, or in industrial manufacturing processes, where its accuracy and sensitivity to weak fields are beneficial.
