Magnetic Sensors - Position, Proximity, Speed (Modules)

The 59140-4-S-04-A is a miniature sensor module in the linear position and speed sensor family from Adafruit Industries. This magnetic sensor module is specifically designed to accurately measure linear position and speed of a moving magnetic target. It does this by sensing subtle changes in flux density of the magnetic field emitted by the target.

The 59140-4-S-04-A magnetic sensor module uses Hall effect technology to accurately measure relative displacement and speed of a moving ferrous target. This tool is made of a pair of Hall effect-based linear sensors, each with its own on-board amplifier and analog-to-digital conversion capabilities, allowing it to independently report the displacement and speed of a target to a digital system.

Application Field

The 59140-4-S-04-A magnetic sensor module is ideal for applications such as measuring linear position and speed in automation and robotics, industrial control panels, and consumer applications. This module is perfect for equipment with limited space and requires a reliable position measurement system with sophisticated detection capabilities. It also provides a simple and robust way to measure the speed of a moving object by detecting changes in the emitted magnetic field.

The 59140-4-S-04-A module can be implemented in applications with a wide variety of mechanical properties, such as actuators, motors, and cylinders. This module is designed to measure position and speed even under conditions of high vibration, shock, and extreme temperatures.

Working Principle

The 59140-4-S-04-A magnetic sensor module is a pair of Hall-effect-based linear sensors. Each Hall sensor contains an intrinsic semiconductor which, in the presence of a magnetic field, serves to generate an output voltage related to the strength and direction of that field. This sensor works by sensing the strength and direction of a magnetized object. As the object moves, the relative position between the sensors and the magnetic source will change, causing the output signal to fluctuate accordingly.

The 59140-4-S-04-A also contains a pair of on-board amplifiers and an analog-to-digital converter, which provide a very accurate measure of displacement and speed of a moving target. The specialized circuitry of the module enables it to measure both displacement and speed in a simultaneous fashion. This versatility of the module allows it to be used in applications that require both accuracy and speed.

The 59140-4-S-04-A magnetic sensor module is a high-performance tool that offers precise and reliable linear position and speed measurement. Its miniaturized size and low power consumption make it ideal for a variety of applications where space and power consumption are important considerations.
