Product description
Supply voltage: 5V (3.3V is also available)
Wiring: Red-5V Black-GND
Output Signal: 5Vp-p two quadrature signal output
Two signal lines, yellow and blue (due to different production batches, sometimes the signal line may be green, does not affect the use), yellow and blue are two TTL levels (can be directly connected to the microcontroller) signals (Note: The positive and negative reversal is based on whether the two levels distinguish between forward and reverse.
Important note: There is no output for long time blocking or no blocking. As phase detection, only the rising edge and falling edge of the beam will have waveform output, so it will only be possible to rotate the code wheel or switch back and forth with opaque objects. Wave output, at high speed, similar to sine or sawtooth. The multimeter test has always been around 0.1V, which is invalid. Please use the oscilloscope or the acquisition port of the MCU.

Package Includes:
1 x Photoelectric Speed Sensor Module
