Taiss/AB 2 Phase Incremental Rotary Encoder 600P/R DC 5-24v Wide Voltage Power Supply 6mm Shaft （ 1 Years Warranty）600P/R

I'm using this in computer peripheral application, and it works as specified. I'm powering it with 8V using a boost converter from the 5V supplied by the USB bus, and it works fine on this supply. I haven't measured how much it draws.

Very well priced and functional for a hobby grade encoder. Easily mated with a ESP32 for a motor drive project. Using this encoder required two pull-up resistors as the ESP32 IO's did pull up was not sufficient to give a clean signal.

Pretty decent encoders. If you want to use 5V directly they have provisions on the PCB. The regulator has a solder bridge between the input and output. Simply connect the bridge with a ball of solder or with a 0805 0 ohm resistor. Like wise on the back of the PCB there are two 0805 locations for pullup resistors. I used 10K and the output works great when connected to a DRO.

Product works fine but the specified 5v input is not correct. Product will not work at this voltage. I was able to make it work with a 12v supply.

I usually don't write product reviews, but this encoder works and it works well. I used it with the hardware quadrature decoder on the Arduino Due and even at 1000 RPM, it does not skip a pulse. I bought the 600p/r version and was under the impression that it was total quadrature rising/falling edges, but it turned out to just be the rising/falling edges of a single phase. This means that the resolution is actually 2400 total rising and falling edges pulses per revolution.
