Magnetic sensors, also known as Hall-effect sensors, are solid-state devices that exploit the unique properties of certain materials to detect the presence of a magnetic field in a device’s vicinity. Of all the magnetic sensors available, those from Honeywell, such as the MRUS52F, are designed for the most demanding applications, offering precison performance and dependability. In this article, we’ll look at the MRUS52F’s application field and working principle.

MRUS52F Application Field

The MRUS52F is a three-lead solid-state, Hall-effect switch with an operating temperature range of -40 ºF to +180 ºF (-40 ºC to +82 ºC). It is designed to switch in response to the presence of a magnetic field and is used in a variety of applications, including the detection of objects in automation systems, machine tool edge detection, and fuel level sensing in marine vessels.

The MRUS52F can detect magnetic fields with a wide range of levels—from 20 gausses (2 mT) in its standard version all the way up to 100 gausses (10 mT) with the high-level version. This makes it well-suited for automotive and industrial applications. It is also available with optional dual output versions for improved sensing capabilities.

MRUS52F Working Principle

The MRUS52F switches in response to the presence of magnetic fields within its detection range. The MRUS52F is composed of three main parts: the coil, Hall-effect element, and a controller. The coil is integrated into the device and is used to generate a magnetic field, which interacts with the Hall-effect element to generate an electrical signal.

The Hall-effect element is a semiconductor element made from a material with high electron mobility, such as gallium arsenide. When the generated magnetic field passes through it, it generates a voltage, which is then passed on to a controller. The controller uses this voltage to determine if a switch should be activated or not.

The MRUS52F has a hysteresis of 5 mT, which means that it must receive a signal with an intensity of 5 mT higher or lower than the one it was previously exposed to in order to change its switching state. This provides the MRUS52F with excellent signal stability and noise immunity.

Conclusion

The MRUS52F satisfies the demands of the most demanding applications, offering precision and dependability. It is capable of detecting magnetic fields with a wide range of levels, from 20 gausses (2 mT) to100 gausses (10 mT), making it well-suited for automotive and industrial applications. With its hysteresis of 5 mT, the MRUS52F offers excellent signal stability and noise immunity.
