The 55140-3M-03-E (hereafter referred to as the ‘Sensor’) is a type of magnetic sensor from the range of modules designed for position, proximity, and speed. In this article, we’ll be exploring the applications and working principle of this particular model.

The Sensor is used in the detection and measurement of changes in the location of a target object, such as in robotics and manufacturing. With a rated operating temperature of - 40 degrees Celsius to 85 degrees Celsius, the Sensor is highly versatile and suitable for both indoor and outdoor applications.

The Sensor has a detection range of up to 3 meters and is capable of detecting objects from a wide range of distances, allowing for precise positioning in all kinds of situations. Its ability to accurately discern the location of an object makes it ideal for use in robotic applications, such as in navigation, robotic arms, and automatic palletizing.

The Sensor can also be used to measure speed (rpm). This is done by evaluating the variation in magnetic field values as thetarget object passes the Sensor. This allows for accurate tracking of the object’s speed and direction. Therefore, it can be used in automotive, industrial, and other mechanical applications, where speed information is needed for accuracy and/or safety.

The Sensor has a high-sensitivity variable magnetic reluctance element with three integrated Hall ICs, enabling it to detect variations in magnetic fields with impressive accuracy. The integrated analog voltage regulator provides the necessary external voltage supply for the Sensor, eliminating the need for an external power module.

The Sensor works by sensing the magnetic field of a target object and generating a voltage output that varies with the position of the object. This voltage signal can then be fed into an amplifier and conditioned by an analog-to-digital converter to provide precise readings of the object’s position.

The Sensor also incorporates a unique integrated circuit that maintains the accuracy of the reading by automatically compensating for temperature changes. This allows the Sensor to consistently detect even the smallest variations in the target object’s position, making it suitable for highly precise and reliable applications.

To sum up, the 55140-3M-03-E Sensor is a powerful and versatile module that can be used for a wide range of applications, from robotics to automotive. Its high sensitivity, robust design, and temperature stability make it an ideal choice for precise and reliable positioning and speed measurement.
