The ATS642LSHTN-I1-T is a Magnetic Sensor - Switch (Solid State). It recognizes a change in a magnetic field, is sensitive to the flux density, has a fast response time and can also let the users know when a clear direction is provided. It is also highly reliable and not prone to mechanical failure or degradation even when exposed to harsh environments.

The ATS642LSHTN-I1-T application field is an ideal choice for applications like automotive, industrial, medical, security, and others where magnetic switches are required. It can function as an audio signal, as an alarm, or as an indicator light to provide awareness to the user. The switch can be used to detect the presence of a target and be used to activate an action based on the detections.

The working principle of the ATS642LSHTN-I1-T is based on the Hall effect. This operating principle was discovered by physicist Edwin Hall in 1879, and it measures the current density of a material. When the magnetized material is placed within the sensing region of the device, a Hall voltage is created and the switching signal is provided. This signal relays the presence or absence of a magnetic field. It is designed to be sensitive to the magnetic field and provide a clear signal when the field is present.

The ATS642LSHTN-I1-T has a hysteretic behavior which imposes a requirement that the magnet must sufficiently move away from the switch before it is activated again. This is beneficial in applications where an indication needs to be given when the target has moved away from the device, providing greater accuracy than other technologies.

The switch has a state change when the magnetic field increases beyond a pre-defined threshold. It will then turn OFF when the field reduces below the release threshold. This state change is designed to remain consistent even in the presence of noise or extreme fluctuations in the environmental conditions.

The ATS642LSHTN-I1-T features an internal pull up resistor to assure a low-active state. It also features an open collector output which needs external pull-up resistor and it is capable of operating from a wide range of temperatures (-40°C to +125°C).

The ATS642LSHTN-I1-T features these characteristics to ensure a robust and reliable performance in a wide range of applications. With its quick response time and sensitivity to the flux density, it has become a popular solution for many different applications.
