Magnetic sensors are position, proximity and speed modules that measure the effect of magnetic fields. The most common types are Hall effect sensors, magneto-resistive sensors, and magneto-inductive sensors. Different types of these modules have different advantages, depending on the application. The 59140-4-T-04-A is a Hall effect sensor and has the following application field and working principle.

Application

The 59140-4-T-04-A is applied when reliable, accurate and consistent measurements of distance, speed and magnetic field presence are necessary. Some of its applications include wheel speed and angle measurement in automotive and industrial systems, current detection in motor drive systems, presence of small shiftable objects like levers, switches, and sensors in automation systems.

Working Principle

This device works off the principle of a Hall effect. The Hall effect refers to the production of a voltage difference across an electrical conductor when a magnetic field is applied perpendicular to it. This type of sensor is non-contact and operates with high precision and repeatability. It is made up of an integrated circuit with an output amplifier and Hall effect plates. When the magnetic field passed by an object comes near the Hall effect plates, the Hall field in turn creates a voltage in proportion to the strength of the magnetic field. This amplified voltage signal is then used as an indication of the presence of the magnetic field.

In Summary

The 59140-4-T-04-A position, proximity and speed module primarily uses the Hall effect principle to measure the distance, speed and magnetic field presence with high accuracy. The main applications of this magnetic sensor are in automotive and industrial systems, current detection in motor drive systems and presence detection of small shiftable objects such as switches and levers. It is a non-contact and reliable device that can measure magnetic fields accurately and consistently.
