59070-4-U-04-A Application Field and Working Principle

59070-4-U-04-A magnetic sensors belongs to a type of magnetic sensors - Position, Proximity, Speed (Modules) - which are widely used in a mixed range of industrial applications.

These magnetic sensors is an indispensable part of a variety of devices in the modern world. It can be used in robotic arm repetition positions, coil end turns, adhesive dispensers and other feedback applications. It is compact, reliable, and easy to install.

This type of sensor has two main components, a sensor and a magnet, and is composed of three parts. The sensor is a sensing element and is generally made of ferrite materials. A permanent magnet can be placed near the sensing element. Finally, there is a signal output such as an analog output voltage or a current output.

The working principle of the sensor is very simple. When the distance between the magnet and the magnetic sensing element changes, the change of the external magnetic field and the corresponding generated magnetic flux change the resistance value of the magnetic sensing element, which is reflected in the output voltage or current.

The 59070-4-U-04-A magnetic sensor is designed to detect the position of magnetic objects, such as doors, windows, toolholders, switches and machine parts. The advantages lies in its accuracy, durability and immunity to interference.

For example, when the distance between magnet and sensor changes, the analog voltage output changes with the changes. Such changes are ideal for providing feedback to a controller to enable precise positioning of a robotic arm or an actuator.

The 59070-4-U-04-A magnetic sensors are also known for their noise immunity and reliability. By adding a certain shielding device to the circuit, it can eliminate the interference of various external magnetic fields to the feedback signal and ensure the accuracy of the signal.

The sensor can also be used for speed measurement. By attaching a rotating magnet onto a rotary device, the output is provided with a pulse train, the frequency of which is proportional to the speed of the rotary device. This eliminates the need for complicated speed sensors, such as encoders.

In conclusion, the 59070-4-U-04-A magnetic sensors is versatile and can be used for a wide range of applications. Such as precision feedback on robotic arms and actuators, measurement of shaft speed and changes in magnetic field density.
