A1123ELHLT-T Magnetic Sensor – Solid State Switch
A1123ELHLT-T is a magnetic sensor – solid state switch (SSS) which uses a Hall effect device as the active element. It has a wide range of applications in numerous electronic systems, such as in industrial and commercial products for positioning, switching and triggering functions. This versatile switch has a high sensitivity and low power consumption, making it ideal for low voltage applications.
A1123ELHLT-T is composed of an integrated circuit (IC)based device package with two Hall effect elements. One Hall effect element consists of a magnet and a Hall effect transistor, while the other is a follower circuit. The two parts are connected in series, so that when a magnetic field passes through the Hall effect transistor, a voltage shift occurs. This voltage shift is measured by the follower circuit in order to determine the degree of magnetization.
The working principle of the A1123ELHLT-T magnetic sensor – solid state switch is based on the principles of Hall effect. When a magnetic flux is passed through the active element, which comprises the two connected Hall effect elements, the voltage output enhances. The same output is detected by the follower circuit, which further enhances the output. The combined signal is then processed for further usage.
A1123ELHLT-T provides a wide range of application in industrial, commercial and personal electronics. Its high sensitivity and low power consumption makes it an ideal choice for low voltage applications. It is capable of measuring the magnetic field intensity and the position of a magnet. This makes it suitably suitable for use in tachometers, temperature and humidity sensors, fan speed controls, and automobile ignition systems. It is also used in automated machines, robotics and position measurement systems. Furthermore, it is a widely used in refrigerator temperature detection, flow-meters, security systems, and alarms.
A1123ELHLT-T can be more accurately used for positioning. It is an ideal device for precise position control, such as for controlling actuators or valves in gas or liquid flow machines. The magnetic field can be used to precisely control the position of a motor or cylinder. It can also be used in the medical field for precise, automated positioning systems.
The A1123ELHLT-T is a versatile and reliable magnetic sensor – solid state switch which provide a wide range of applications. Its high sensitivity and low power consumption makes it ideal for low voltage applications. It can be used for precise position control in industrial, commercial and medical systems for switching, triggering and position measuring functions.
