Common failure of rotary encoder！

Rotary encoder four most common failure


Rotary encoder for rapid development of increasingly electronic components market, small rotary encoders, high performance, a variety of features, making more and more companies choose alternative rotary encoder using rotary potentiometer, rotary encoders in the use of the process failure is normal, so in practice, common fault, what does?

1, the axis of rotation will be deformed, this is due to the general fixed nut or locking potentiometer over tighten the lock nut, here to give advice in the nut, spindle nut surface higher than about lmm the above.

2, the rotation is not flexible, often due to the inner shaft into the dust or oil caused thousands of dead, which generally take drops in the shaft at the small amount of gasoline, and gasoline drip edge while rotating the shaft.

3, poor contact, divided into two cases, the first reed insufficient elasticity, the second is poor contact between the carbon layer and leads to the foot. In both cases, the repair can be taken, the first case will be the nail root and porn appropriate press down the second case is the use of pliers to clamp the foot leads.

4 kinds of fault usually unambiguous warning, then the need to replace the battery, if the reference point position memory loss, must perform reference point return operation.

These are the rotary encoder in use common fault, failure is normal, we failed to find a timely resolution symptomatic.
