Working principle

The operation of the ATL684LSNTN-T is based on the principle of anisotropic magnetoresistance (AMR) technology. In brief, the sensor is composed of an AMR element that changes resistance when subjected to a magnetic field. When the field strength is below a certain threshold, the device behaves as an open circuit and output remains in the off state. The device is then said to be in its "un-activated" state. When this threshold is exceeded, the resistance of the element drops and the device is said to be in its "activated" state. The output voltage of the device then drops to the "on" state.

The ATL684LSNTN-T is designed to detect the presence of magnetic fields and respond accordingly. This is accomplished by a combination of an AMR element and a control circuit that changes the state of the sensor. The control circuit consists of a resistive-capacitive network (RC network) which is used to sense the presence of the magnetic field. When the threshold level is exceeded, the RC network activates the sensing circuit by providing a voltage to the AMR element. This change in voltage increases the conductivity of the element, allowing more current to flow and changing the output state of the sensor.

The ATL684LSNTN-T is considered to be a very reliable magnetic sensing switch due to its rugged construction and high-sensitivity. Unlike other magnetic sensing switches, the ATL684LSNTN-T only operates on very low-level magnetic fields and is not affected by a wide range of external disturbances, such as vibration, temperature fluctuations and magnetic noise. This allows the sensor to offer accurate performance and long-term stability without the requirement of frequent recalibration.

In addition, the ATL684LSNTN-T features an extremely fast response time of 0.5 ms. This makes it suitable for applications that require a high level of precision in a very short amount of time, such as motor control and speed measuring. Lastly, the device is available in several different form factors, making it suitable for integration into a wide variety of applications.

In summary, the ATL684LSNTN-T is an advanced magnetic sensor with solid-state switch designed for use in applications that require accurate, reliable and fast detection of magnetic fields. The rugged construction and highly sensitive AMR element enable the device to maintain a high level of accuracy and stability even in challenging environments. With its fast response time and several available form factors, the ATL684LSNTN-T is an ideal choice for motor control, speed measuring and other similar applications.
