How to detect the encoder quality stand or fall?

Encoder is a kind of common electronic components, but you know how to judge the encoder quality stand or fall? This article to introduce the detection method how good the encoder, everyone can have a try. 1. Rotation performance testing encoder and switch reliability check in check the encoder, the first axis of rotation handle, check whether the shaft rotation is flexible, smooth. If you hear the encoder internal contact resistance and friction sound, then there is something wrong with the quality of encoder. Check the encoder with switch method: when twisted or push-pull shaft encoder, should be able to hear when switch on and off a click is clear. Also can use a multimeter low block check switch on-off situation between the two welding pieces, to judge the stand or fall of the encoder. 2. Nominal resistance detecting encoder nominal resistance a encoder, measurement method as shown in the figure below: first of all to put a multimeter ohm block, and then according to the size of the nominal resistance being measured to choose the appropriate range. The multimeter two pens and pick up the encoder on both ends of A, C, measured at the ends of the A and C is the total resistance for encoder, it should comply with the prescribed scope of the nominal value. Such as multimeter pointer does not move, or resistance differs a lot, suggests that the encoder has been damaged, can't continue to use. 3. Encoder test encoder contact contact condition detection, measurement method as shown in the figure below. Will put ohm block multimeter, and choose the right measurement range, and then A multimeter only pens and pick up the B end of the encoder, pens and connect the other sides of both ends of A, C, volatility encoder shaft at the same time, at this time all play table should be slowly as the deflection of Pointers: when shaft screw to extreme position, encoder value shall be the nominal value or the minimum contact resistance. When reverse rotation handle, the multimeter pointer shall reverse slowly deflection to the maximum or minimum resistance, if turn the handle in turns, multimeter pointer have to beat or suddenly into infinity, suggests that the encoder has a poor contact, can no longer continue to use. 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.
