Re: Cheap encoders
I recieved mine last week. Yes, they are sleve bearings, but I had no problem hooking them up and getting counts up to about 300 rpm. I would not want to use them at high rpm like controlling the velocity of a ball shoot like in aim high. My thought is that they would be fine at the rpm that they would see if the AM tough box is in the KOP and they ship with the encoder 1/4" shaft extension. The key point is the mounting and coupling. Stress on the shaft would eventual cause failure. The other thing is if they maintain a crisp square wave at higher RPM. I would at this time not write them off.
