How to detect the encoder?

Detect encoder quality first customers upon receipt of the goods did one thing! Then detect the encoder, we begin from the following three aspects. Main requirements of the encoder is: (1) resistance meets the requirements. (2) the center sliding side with good contact between the resistor body, a smooth rotation. With encoder switch, the switch part of the action should be accurate and reliable and flexible. So the stand or fall of performance must be checked before using encoder. Some methods of measuring encoder says below: 1, the resistance measurement: first of all, according to the size of the encoder resistance being measured, the multimeter suitable chosen resistance gear, measuring the resistance, resistance value between the AC on both ends of the piece, compared with nominal value, the both are consistent. Twisted sliding contact at the same time, its value should be fixed. If the value is infinite, the encoder is damaged. 2, and then measuring the center side contact with the resistance, the resistance value between BC at both ends. Method is multimeter ohm files in the appropriate range, measuring process, slowly rotating shaft, observe the multimeter reading, normal, reading smoothly in one direction of change, if appear the phenomenon such as beating, falling or impassability, activity contacts have poor contact failure. 3, when the center side slip into the head end or ends, ideally center end and overlap of the resistance value is 0, in actual measurement, there will be some residual value ( Generally depends on the nominal, generally less than 5 Ω) , is a normal phenomenon. Shanghai electronic 26 years, specializing in the production of encoder encoder models complete, we produce kinds of encoders have rotary encoder, straight and smooth encoder, rocker encoder, the motor encoder, switch, encoders, with complete size, can also be customized according to customer requirements, to find find electronic encoder manufacturers.
