1. The proximity sensor cannot recognize the size of the interval from the detected target.

2. The switch is installed within the scale of the detection interval, sometimes there is no signal in the practical inspection (sometimes it can be detected, sometimes it cannot be detected).

3. The practical detection interval is different from the standard detection interval indicated by the sensor. (Can be less or greater than the detection interval).

4. The indicator has a signal prompt, but no signal output; or the signal indicator is always on, and there is no signal change; Maybe the signal is always shining, and so on.

5. There is no action response or signal response after powering on.

6. Interpret multiple sensors together, etc., and connect the response signals of different sensors and connect multiple sensors together.

Measure the resistance between pins 3 and 4 of the sensor side, with a target value of 26.6kΩ - 29.4kΩ, if it is not within the scale, replace the sensor. An encoder is a reactive sensor commonly used in control components that converts physical quantities into electrical signals. It is used in motion control, servo motor, electric spindle and other components to complete the control of motion characteristics. The application market is very wide: such as machine tools, logistics, textiles, printing and packaging, robots, etc. Due to the intensive use of machinery, it is simply a product category in its own right. What are the instruments and tools for diagnosing ABS problems? What are the effects of each? The switch is installed within the scale of the detection interval, and the signal is intermittent (sometimes detectable, sometimes undetectable) in practice. The frequency of false alarms of the nitrogen and oxygen sensor of the J6 export vehicle is very high, and (4) it does not consume urea. After the NOx concentration is measured, the NOx concentration sensor continuously sends the measurement results to the ECU through the AT101 packet in the CAN bus, and if the ECU does not receive the AT101 packet, the fault will be reported. Defects in the functionality of the chip CPU of the electronic control device (EBCM). Automatic control of data flow direction: After hardware processing of data flow direction problems, the data transmission direction is automatically determined and manipulated. RS-485 Hub Function RS485 Hub is a high-performance optical resistance reinforced RS485 bus interface distributor.
