PI90LV031AW is an interface-level incremental encoder, adjacent counter difference transceiver that is used for level sensing and counting applications. It is an ideal solution for applications such as automatic assembly and inspection, process validation, and data logging. The PI90LV031AW includes a dual-channel transmitter, a differential receiver and a low-power microcontroller. The dual-channel transmitter provides two channels of feedback data to the receiver, which then determines the relative position of the encoder wheel. The microcontroller is responsible for interpreting and outputting the differential signals to a compatible external circuit.

The PI90LV031AW is available in two varieties, the DT-A and DT-B. The DT-A variant is an incremental encoder with four data lines, while the DT-B is a differential transceiver with eight data lines. Each encoder wheel has eight segmented sections that are used to detect motion. The incremental encoder offers resolution up to 250 counts per revolution (CPR). The differential transceiver provides up to 2000 CPR.

The PI90LV031AW driver and receiver pair allow for level sensing applications with resolution up to 2000 CPR and fast response times. The high performance design makes it suitable for a variety of level-sensing applications such as liquid tanks, gas meters, and motorized conveyors. The integral Hall-effect transmitter and receiver pair sense the exact location of the encoder wheel by providing feedback of the wheel\'s position to the microcontroller. The microcontroller then converts the feedback into an analog signal that can be interpreted by an external circuit.

The PI90LV031AW application field consists of various industrial, security, and consumer applications. It can be used for controlling automated machinery, such as conveyor belts, sorting systems, and robotic arms. The PI90LV031AW can also be used in a variety of security applications, such as access control systems and camera systems. In addition, it can be used for product validation in food processing applications and for light effect applications, such as RGB illumination.

The working principle of the PI90LV031AW is based on the Hall effect, which is a type of contactless sensing technology. A low-power pulsing magnetic field is generated around the encoder wheel and this field penetrates the hall-effect sensor. Each segment of the encoder wheel contains a magnet and when the wheel rotates, the magnets induce varying magnetic fields in the hall-effect sensor. The strength of the induced magnetic field is detected by the hall-effect sensor which then sends a series of pulses to the microcontroller. The microcontroller then interprets these pulses to determine the relative position of the wheel.

The PI90LV031AW is a highly versatile interface-level incremental encoder, adjacent counter difference transceiver that is suitable for a wide range of level sensing and counting applications. It is designed for fast response times, high resolution, and low power consumption. With its easy to use interface and high performance design, the PI90LV031AW is the ideal choice for any application requiring level sensing or counting capabilities.
