A1211ELHLT-T Magnetic Sensors - Switches (Solid State) is a magnetic switch developed by Allegro Microsystems. It is designed to sense the presence of a magnetic field, and to switch on/off according to predetermined conditions. It is commonly used in consumer applications such as automotive and industrial switchgear, as well as in security applications such as burglar alarms.

The A1211ELHLT-T is an open-circuit Hall-effect switch with superior sensitivity, high operation temperature ranges from -25°C up to 125°C, and low power requirement. It utilizes the Hall-effect principle to sense the presence of a magnetic field, and to switch on/off at predetermined conditions. When it is exposed to a magnetic field higher than 3mT, it will switch on. When the strength of the magnetic field is lower than 2.5mT, it will switch off.

The A1211ELHLT-T is able to sense the presence of a ferrous metal in its sensing range which allows it to be used for non-contact switching. This makes it an ideal solution for automated processes in industrial and consumer applications, allowing for reduced wear and tear on mechanical switches. It is also highly reliable and robust, providing a long service life in even the harshest environments.

The A1211ELHLT-T is suitable for applications where reliable, low-cost magnetic switches are required. It is available in a range of different packages, making it suitable for most mounting requirements. It also incorporates a bipolar field compensation which makes it suitable for use in both high and low magnetic fields. This makes it an ideal solution for applications in extreme environments.

The A1211ELHLT-T can be used in a variety of applications, such as automotive switchgear, intruder alarms, and industrial switchgear. In automotive applications, it can be used for door/bonnet open detection. In industrial applications, it can be used for valve position sensing, flow sensing, and pressure sensing. In security applications, it can be used for window/door open detection and motion detection. It is also ideal for detecting the absence/presence of magnetic objects in automatic assembly lines.

In conclusion, the A1211ELHLT-T magnetic sensor-switch (solid state) is a highly reliable, low cost solution for sensing the presence of a magnetic field. It is suitable for a wide range of applications in the automotive, industrial and security industries. Its open-circuit Hall-effect design makes it ideal for non-contact switching, while its bipolar field compensation ensures it is suitable for use across a range of magnetic fields. With its long service life and robust construction, the A1211ELHLT-T is an ideal solution for automated processes in a variety of applications.
