Magnetic Sensors - Linear, Compass (ICs)

A1356LKB-T is a high-performance linear Hall-effect sensor IC. Its advanced linear Hall-effect technology provides accurate, temperature-stable sensing. The A1356LKB-T integrates a high-performance Hall-effect sensor, analog and digital condensers, a voltage regulator, and two open-collector outputs into a small package that houses a dual-element latching signal-conditioning circuit. The device is optimized for accurate operation over a wide temperature range of -40°C to +125°C.

Application Field

The A1356LKB-T is designed for contactless motion sensing and positioning applications. It can be used to detect the motion of rotating machines, linear actuators, and linear motion positioners. The A1356LKB-T is also designed to detect the motion of ferromagnetic elements with a high degree of accuracy, and it is suitable for applications requiring precise high-resolution sensing.

The A1356LKB-T is also used in many industrial and automotive applications such as motor speed and efficiency monitoring, and gear wheel position and velocity detection. In addition, the A1356LKB-T can be used for detecting the position of a door or window, for controlling the speed of a motor, or for controlling the position of a robotic arm.

Working Principle

The A1356LKB-T is based on Hall-effect technology. The device contains a magnetically sensitive element, which detects changes in the magnetic field around it. When a magnetic field is applied, the electron flow in the element is disturbed, producing an electrical signal. The device has an analog output that is proportional to the level of the magnetic field.

The A1356LKB-T uses a dual-element latching circuit to provide accurate signal conditioning. The latching circuit consists of two switching elements: a Hall-effect sensor and a switched power supply. The Hall-effect sensor provides a signal proportional to the applied magnetic field and the switched power supply is used to provide a stable analog voltage reference.

The device also contains two open-collector outputs which can be used to drive external loads such as LEDs or relays. The outputs are latched, meaning they remain in a “latched” state until the magnetic field is changed. This feature enables the device to be used for motion sensing applications.

The A1356LKB-T is an ideal solution for motion sensing applications that require low power consumption and accurate results. It is capable of detecting a wide range of magnetic fields with a high degree of sensitivity, and its dual-element latching circuit ensures accurate signal processing.
