The A1103ELHLT-T is a magnetic sensor from the family of Magnetic Sensors - Switches (Solid State). The device boasts a number of advantages including high-accuracy sensing, a minimum lag time between the sensing of a target and the outputting of an alarm signal, and a no-contact design with elongated magnetic sensing range capacities. This document provides an overview of the working principles and applications of the A1103ELHLT-T.

Overview

The A1103ELHLT-T contains a Hall effect device, current drive circuitry, a signal processing circuit, and a load circuit. The Hall element is constructed with a built-in magneto-resistor element. When a magnet is positioned near this element, the generated magnetic field is detected and sensed by the Hall element, resulting in an output voltage. The current drive circuit supplies a direct current voltage to the Hall element. The magnitude of this supply voltage is used to adjust the sensitivity of the Hall element. The signal processing circuit amplifies and shapes the output signal, which is then fed to the load circuit.

Working Principle

The A1103ELHLT-T is a solid-state switch operated on a magnetic field. When a target magnet is present and a current is applied, the magnetic field between the switch and the target magnet will cause an output from the Hall Effect device. This output is then amplified and sensed in the signal processing circuit, which then supplies an alarm signal to the load circuit. The no-contact design and variable magnetic sensing range capabilities of the A1103ELHLT-T allow it to accurately sense a target magnet regardless of the distance or the angle of its position.

Applications

The A1103ELHLT-T is used in a wide variety of applications. It makes an ideal choice for security systems or applications requiring a secondary level of detection, such as for non-contact mechanical switches, multi-level sensing of metallic objects, and connectionless switching. Other applications include magnetometry, communications, flow meters, and automotive applications. Additionally, the extended sensing range and non-contact design of the A1103ELHLT-T make it ideal for use in extremely rugged applications, such as those encountered in the mining and construction industries.

Conclusion

The A1103ELHLT-T is a high-accuracy sensor from the family of Magnetic Sensors - Switches (Solid State). It is used in a wide variety of applications, including security systems, magnetometry, flow meters, communications, and automotive applications. The device boasts a number of advantages including a minimum lag time between the sensing of a target and the outputting of an alarm signal, and a no-contact design with elongated magnetic sensing range capabilities.
