Magnetic sensors are quickly becoming one of the most important tools for a variety of applications. The 59021-1-T-02-E sensor has a unique feature in that it combines two types of magnetic sensing technologies. On one hand, the sensor detects the absolute field strength in a given linear direction. It then uses this information to measure angular position and / or detect the presence of a ferromagnetic material. This makes the sensor ideal for applications such as angular encoders, speedometers, motion detection and other similar tasks that are usually quite difficult to accomplish with other methods of sensing.

The 59021-1-T-02-E consists of two core components, the Hall effect sensor and the magnetoresistive (MR) element. The Hall effect sensor works by measuring the change in the magnetic field as the hall probe nears a magnet or magnetized material. This is then detected by the analog circuit, resulting in a corresponding voltage that can be directly measured. The MR element works on the same principle, but instead of measuring a change in voltage it is simply measuring the resistance that is generated across the narrow gap between the sensor and the magnetized material.

The detection range of the 59021-1-T-02-E is quite wide, which makes the sensor extremely flexible and able to serve different types of applications. It can be used to measure the absolute linear position of a magnetized object from 0 to 1.5mm, as well as operating at speeds up to 1000rpm. The accuracy of the sensor is based on the environment and applications which can range from 0.2 to 0.5mm when measuring absolute linear position, and 0.1rpm when measuring speed.

The 59021-1-T-02-E can also be used for proximity sensing and motion detection. By adding an external magnet, the sensor can detect the proximity and motion of that magnet. In this case the sensitivity and accuracy uses the internal Analog gain parameters of the device, and can be adjusted depending on the applications requirements. The sensing range varies from 0 to 10mm depending on the strength of the external magnet. As with any magnetic system there are certain sources of interference that need to be taken into account, such as stray magnetic fields or large pieces of metal.

The 59021-1-T-02-E is a very versatile and cost effective position sensor. With its combination of Hall effect and magnetoresistive technologies it is able to serve a diverse set of applications. As a result it is quickly becoming one of the most popular position sensors on the market. With its wide operating range and accuracy, it is sure to be a dependable option for a variety of tasks.
