The D40R-LPU-21-05 from Pepperl+Fuchs is a magnetic sensor module and is typically used to detect the angular position of a permanent magnet. This type of magnetic sensor module is typically found in industrial applications where extreme accuracy over a wide temperature range is required. It detects changes in the magnet field due to either movement of the magnet or changes in its environment and then translates this information into an electrical signal.

The supply voltage range of the D40R-LPU-21-05 is 6V to 24V, with high input impedance protecting the differential collective input signals from voltage surge effects. Its overall operation is symmetrical and balanced, and provides protection against the field interfering from outside, enabling accurate and reliable readings.

The output of the D40R-LPU-21-05 is monitored and controlled by an integrated processor. This processor is responsible for digitizing the signals from the sensor, then carrying out any logical calculations, and thus it is the CPU of the module. The processor is made up of a controller module, a signal amplifier, a shaper and a data processing unit. The signal amplifier provides an amplified signal from the magnet field to the shaper module. The shaper filters out the common mode noise, rectifies and shapes the signal, and passes it to the data processor. The data processor carries out any logical calculations required and then sends it the output to the controller.

The controller is responsible for providing all the operating parameters for the module, and controlling the voltage supplied to the magnet. The controller can be programmed to provide different operating parameters, allowing the module to be used for various applications. The voltage supplies provided are adjustable, allowing the module to zero itself in different locations, so it can detect the angle of the magnet from a range of positions. When the angle is within the sensitivity range of the module, the signal is amplified, shaped and sent to the controller, and then output as either a discrete logic signal or analog signal.

In summary, the D40R-LPU-21-05 is a magnetic sensor module which is used to detect the angle of a permanent magnet. It features high input impedance, a symmetrical and balanced operation, and the ability to be programmed for various applications. With the adjustable voltage supply, the module can zero itself in different angles, providing accurate readings within its sensitivity range. The output of the module is a discrete logic signal or analog signal from the controller.
