Optical Encoder Speed Sensor Module - For Freescale Smart Car Models C/d/e, Photoelectric Speed Measurement

Optoelectronic encoder/speed sensor encoder Freescale intelligent car CBDE car model Baby description: Photoelectric speed measuring sensor Baby pictures Codec technical parameters: Number of lines: 100 lines Outer diameter: 22mm Inner hole diameter: 3.5mm Thickness: 0.3mm Material: Alloy Steel Production process: laser cutting processing Installation method: Use the installation column sent by the seller to fix it. Technical parameters for speed measurement pipe fitting: Tube manufacturer: original HP, US Supply voltage: 5V (3.3V is also available) Wiring method:5V         GND Output signal: 5Vp-p two-phase signal output (see the figure below). Two signal lines, one yellow and one blue (since the production batches are different, sometimes the signal lines may be green and do not affect use), yellow and blue are 2 TTL levels respectively (you can directly connect to microcontrollers) signals (Note: The positive and reverse rotation is determined by these two levels to distinguish whether it is forward or reverse rotation) (Suppose A B is the signal line) A has a pulse first, which proves to be a positive turn B has pulse first, it proves to be an inversion Important Note:Block for a long timeorNot blockingThere is no output. As phase detection, there will be waveform output only on the rising and falling edges of the counters. Therefore, when rotating the code disk or switching back and forth with an opaque object, there will be square wave output. In high-speed state, it is similar to sine wave or sawtooth wave. See the video demonstration below for details. The multimeter test has always been around 0.1V, which is invalid Please use the testOscilloscopeorThe acquisition port of microcontroller& 12290;
