Introduction

The ATS673LSETN-LT-T is a magnetic sensor switch that is part of the family of solid state magnetic sensors. Being a solid state sensor means that the switch is electronic based rather than mechanistic. Magnetic sensors are used in many different applications such as vehicles, robotics, automation, consumer electronics and medical devices and are becoming increasingly important in these fields due to their ability to detect and measure a change in magnetic field. One major benefit of the ATS673LSETN-LT-T is that it can be used to determine the position of an object or person and take action based on the information.

ATS673LSETN-LT-T Application Field

The ATS673LSETN-LT-T is a popular choice for magnetic sensing in things like vehicles, boilers, security systems, robotics, automated doors and windows, and many more. For instance, its use in vehicles can aid in providing enhanced security, detecting movement, and allowing for detection over a wide range of distances. Its use in security systems can alert when a door or window is opened. As well as, it can be used in robotics for the automatic and accurate detection of items and peoples.

ATS673LSETN-LT-T Working Principle

The ATS673LSETN-LT-T magnetic sensor switch relies on a Hall Effect principle to detect changes in a magnetic field. Its operation works by using magnetic field lines to intersect with the sensor’s active area. This causes a voltage proportional to the strength of the magnetic field to be applied to the output of the switch. When the magnetic field strength is strong enough, it triggers the switch to activate.The sensor comprises of four major components, a disc, a magnet, a housing and a PCB. The sensor works best when the magnet is brought close to the disc. The magnetic field lines then intersect the Hall-Effect sensing element which is an integrated circuit (IC) placed on the PCB. When the magnetic field is strong enough, it is passed through the ceramic ferrite plates and then onto the Hall IC. This causes a change in the magnetic flux which is then translated to an electronics signal that powers the switch given the same output rate.

Conclusion

The ATS673LSETN-LT-T is a solid state magnetic sensor switch that is integrated with ceramic ferrite plates, a Hall Effect circuit, and a magnet. The switch is most commonly used in vehicle, robotics, and security systems, but can also be used in more advanced applications such as medical devices. Its operation is based on the Hall Effect principle of detecting changes in a magnetic field. When the magnetic field is strong enough, it triggers the switch to activate, allowing for the accurate detection of items and people in a wide range of applications.
