Magnetic sensors, oftentimes referred to as switches, are devices used to detect the presence of a magnetic field or to measure its strength. Solid state magnetic sensors switch (SSMS) use a solid-state Hall effect element to detect the presence of a magnetic field and to change the resistance of the device accordingly. The A3260ELHLT is a Hall effect device that incorporates a self-correcting digital output for open-loop current sensing and position sensing applications. This article explains the application field and working principle of the A3260ELHLT.

Applications

The A3260ELHLT is designed for use in automotive and industrial applications that require proximity and position sensing of a nearby magnetic field. This includes applications such as sensing the position of a throttle in automotive systems, sensing the position of a camshaft in industrial machinery, and monitoring the speed of a motor or gearbox in various applications. It is also suitable for applications requiring a precise measurement of small changes in a magnetic field.

In automotive applications, the A3260ELHLT can be used for applications such as detecting a vehicle’s gear position, its throttle position, or engine rpm. It can also be used for axle speed monitoring in trucks and trailers, as well as for temperature and pressure sensing, among other applications.

In industrial applications, the A3260ELHLT can be used for camshaft monitoring or the detection of small changes in a magnetic field. It is also suitable for applications such as level detection and overcurrent protection, as well as for non-contact speed sensing. It is available in a range of operating temperatures and with a wide input voltage range.

Working Principle

The A3260ELHLT utilizes the Hall effect to sense the presence of a magnetic field and to switch its output accordingly. The Hall effect is a phenomenon in which a voltage is generated in a conductor that lies perpendicular to a magnetic field. When the A3260ELHLT is exposed to a magnetic field, the Hall element creates a voltage which is proportional to the strength of the magnetic field. The voltage generated is then compared to internal reference voltages to determine the output logic level.

The A3260ELHLT also utilizes self-correcting digital output technology that allows it to maintain precise accuracy over temperature fluctuations and time. This technology utilizes reference tables which are used to self-reprogram the internal reference voltages according to environmental conditions, thus maintaining precise performance over long periods of time.

The A3260ELHLT is also designed for use in open-loop current sensing applications. The Hall element generates a voltage proportional to the amount of current passing through it. This voltage is then compared to internal reference voltages to determine the output logic level, thus providing accurate current monitoring.

The A3260ELHLT is an integrated circuit (IC) with an output voltage of 1.65V max at 15mA operating current, making it suitable for a variety of applications such as automobile, industrial and consumer electronics. It is available in SOT23 or TSOT23 packages and comes with an over temperature protect and a temperature sensor.

In summary, the A3260ELHLT is a Hall effect device designed for automotive and industrial applications that require proximity and position sensing of nearby magnetic fields. It is suitable for applications requiring a precise measurement of small changes in a magnetic field and features self-correcting digital output technology which allows it to maintain optimal accuracy over time and environmental conditions. It is available in SOT23 or TSOT23 packages and offers a 1.65V max output voltage at 15mA operating current.
