Carbon film encoder failure causes and repair methods
Encoder this kind of electronic components, when we have been using fault may appear problem, because again precision instruments also there will be a failure.
Carbon film encoder will appear the following faults: rotation noise big, pin internal circuit, the phenomenon such as wear resistance, burn, switch damage occurred.
The following to analyze the reasons of these failures and treatment methods.
Carbon film encoder rotation noise big reason and treatment methods of carbon membrane encoder in big rotating noise resistance is the main cause to the wear and tear, make little contact with poor contact between the resistor body, big and small resistance value, resulting in a 'cascades, cascades' voice.
At this time, can use a multimeter according to the method for testing, then you will find Pointers have jump phenomena.
To have this kind of encoder failure of carbon membrane, can use first troubleshooting cleaning method, also is dip in with tweezers clip on the presence of water alcohol cotton ball, with a cotton ball close to the shaft, make alcohol resistance along the axis of injection, and the rotation of the rotor, until the noise disappear.
Carbon film encoder pin internal break reason and processing method when carbon film encoder pin internal circuit, there will be a carbon film encoder doesn't work, that is when the rotating shaft current or voltage without any change in the circuit.
For the volume of carbon membrane encoder, silent failure may occur, or the phenomenon of volume closed tightly, when using a multimeter test between two fixed pin or fixed pin with sliding contact resistance between the pins, its resistance to infinity, or close to infinity, the internal circuit can determine the pin.
Carbon film resistor body caused by flow will also serious burn out.
For open circuit or resistor inside the pin body burn out and open the carbon film encoder, generally inconvenient repair, and adopt the method of replacement.
Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various types of encoder, rotary encoder, straight and smooth encoder, rocker encoder, switch, encoders, such as motor encoder, encoder specifications complete, can perfect to replace encoder brand at home and abroad.
Years old encoder manufacturers can provide customers with a axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom.
Looking for looking for electronic encoder manufacturers.
